AutoCAD 2014 Review: Improving Your Design Workflow

Connectivity empowers a host of new features and functions in AutoCAD 2014

A new release of AutoCAD has become a rite of spring, and for this, its 28th major release of the world’s most popular CAD program, Autodesk, has once again provided customers with a host of improvements. For the past several years, the company’s focus has shifted from empowering standalone individuals to leveraging the power of the cloud, social and mobile computing. With AutoCAD 2014, users can work more seamlessly across platforms, collaborate with other project stakeholders, and access their drawings wherever they go. And a linchpin of that capability is the Autodesk 360 cloud service.
Autodesk ReCap
The new Autodesk ReCap program lets users create and manipulate point cloud project files before attaching them to AutoCAD drawings.
Upon launching AutoCAD 2014, users are once again greeted by a Welcome Screen featuring three panels: Work (tools for creating new drawings and opening existing files), Learn (links to video-based training), and Extend (connections to the Autodesk Exchange app store, Autodesk 360, and social media sites including Facebook and Twitter). Although you can certainly use AutoCAD 2014 as a standalone application, users will want a full-time Internet connection to take advantage of all the new connectivity tools--and will likely remain logged into their Autodesk 360 account whenever they’re using AutoCAD 2014.
Even Better Command Line Tools
One of those new connectivity tools is the ability to do Internet searches directly at AutoCAD’s ubiquitous Command line. Many longtime users continue to access commands by typing. While the Command line saw some significant changes in the last release, its transformation in AutoCAD 2014 is just short of miraculous: The Command line in AutoCAD 2014 now supports AutoCorrect. If you mistype a command, instead of responding with “Unknown command,” the program autocorrects to the most relevant and valid AutoCAD command. For example, if you accidently type TABEL, the TABLE command is automatically launched.
The AutoComplete command entry feature, introduced in AutoCAD 2013, has been enhanced in AutoCAD 2014 to support mid-string search. So now, if you type SETTINGS, the suggestion list displays all commands containing the word SETTINGS anywhere within it, not just at the beginning. Commands in the suggestion list are initially displayed in the order of their usage based on general customer data. But as you continue to use AutoCAD, the order of commands in the suggestion list adapts to your specific behavior.
The Command line in AutoCAD 2014 also has a built-in synonym list. If you type a word, the program returns a command if a match is found in the synonym list. For example, if you type SYMBOL, AutoCAD finds the INSERT command; or type ROUND and AutoCAD finds the FILLET command. And like most things in AutoCAD, you can customize both the AutoCorrect and Synonym lists using the Edit Alias tool on the Manage ribbon.
When you move the cursor over a command name or system variable in the Command line suggestion list, two small icons appear so that you can immediately search for more information in the Help system or on the Internet.
You can also use the Command line to access layers, blocks, hatch patterns, text styles, dimension styles, and so on. For example, if you type DOOR and the current drawing contains a block definition with the name DOOR, you can quickly insert it right from the suggestion list.
To make the suggestion list easier to navigate, system variables and other content are organized into expandable categories. You can expand a category to see the results, or press the TAB key to cycle through each category. You can also customize the behavior of the Command line itself, enabling or disabling various features, changing the suggestion list delay, and adjusting the input search options. Most of the new Command line functionality is also available when using dynamic input.
Improved File Management
While the enhancements to the Command line only become apparent when you type, the new drawing file tabs will probably be the first new features you’ll notice when you start using AutoCAD 2014. The drawing file tabs appear as a bar across the top of the drawing area. Because they do take up some space that could otherwise be used to display drawings, the drawing file tabs can be toggled on and off. When enabled, you see a tab for each open drawing, and can easily switch between drawings by simply clicking on a tab.
The tabs initially display in the order in which drawings were opened, but you can drag and drop tabs to change their order. If there is not enough room for all of the file tabs to display across the drawing area, an overflow menu at the right end of the file tabs bar provides access to the additional files.
A lock icon on a tab indicates that a particular drawing was opened in read-only mode, while an asterisk on the tab indicates that the drawing has been modified since it was last saved. When you move the cursor over a tab, you see preview images of the model and layouts, and if you move the cursor over one of those previews, the corresponding model or layout temporarily fills the drawing area. Plot and Publish tools are also available above each preview image, or you can click on one of the previews to immediately switch to that specific model or layout. You can also right-click on a tab to access tools to create, open, save and close files, including the ability to close all open files except the one on which you right-clicked.
Command line
The Command line now includes auto-correction, synonym lookup, and mid-string auto-completion. You can even preview hatch patterns and blocks directly at the Command line.
AutoCAD
Drawing file tabs make it easier to switch among open drawings, preview model or layout tabs, and even see which drawings have been changed since last saved.
Design Feed
Design Feed enables users to have a virtual conversation with other team members; it also tracks messages and images tagged to the drawing.
Connecting with Colleagues
If a big focus of AutoCAD 2014 is connectivity, the centerpiece of that connectivity is Autodesk 360. The Autodesk 360 cloud-based service is both a secure, web-based central repository for your drawings and system settings, and an online hub for collaborating with colleagues and leveraging cloud-based compute power for creating renderings, performing analysis and leveraging point cloud data.
New in AutoCAD 2014 is Design Feed, an environment in which you can have a virtual conversation with other team members, regardless of their location. Design Feed appears in the form of a new palette when you click the new Design Feed tool on the Autodesk 360 ribbon.
You can use tools in the Design Feed palette to create messages to other team members, and associate those messages with an area or point within the drawing. You can also include images and tag multiple colleagues. Once you post a Design Feed message, it is saved to your Autodesk 360 account along with the drawing, and the people that you tagged receive an email message alerting them of your post. They can then view the drawing and associated posts and reply to those posts using their copy of AutoCAD 2014, AutoCAD WS via any web browser, or the AutoCAD WS app on a mobile device. They can even make changes to the drawing if you’ve granted them permission to do so. Design Feed works wherever you are, and comments sync within seconds.
Connecting with the World
In this latest release, Autodesk has added some of the tools found in AutoCAD Map 3D and Civil 3D to AutoCAD itself. The new geographic location tools in AutoCAD 2014 enable you to import map data into drawing files so that you can see your design within the context of its location. If you render the model, it will automatically have the correct sun angle. If you insert geo-referenced images or blocks into a geo-referenced drawing, they are automatically placed in the correct location and at the proper scale. This enables multiple users to work separately on portions of the same design, such as a housing project, with the guarantee that everything will match when the entire project is assembled. If you have a GPS-enabled device on your computer, you can see your current position in the drawing and mark positions as you walk around.
To add the geographic location to a drawing, you simply click the new Set Location tool on the Insert ribbon. You can set the location using the Autodesk Maps Service or by selecting a KML or KMZ file. To use the Maps Service, however, you must be logged into your Autodesk 360 account.
When you specify the geographic location using a map, you can simply click on the map or search for an address or latitude and longitude. Maps can be displayed as an aerial photo, a road map, or a hybrid of both. When you find the correct location, you drop a marker to select it, automatically applying the corresponding latitude, longitude and time zone. Once placed, you can adjust the elevation, latitude and longitude as needed.
Once a map has been applied to the drawing, it is always displayed below the drawing geometry. You can then trace over the map to identify features on the site. The map can be changed between aerial and road map views, or toggled off completely as needed. Additional tools enable you to mark positions in the drawing and add text to describe those positions.
Capturing Reality
The ability to attach and display point clouds was first added to AutoCAD 2011. While the tools in AutoCAD itself have not changed all that much, Autodesk has included a new program called Autodesk ReCap as part of the AutoCAD 2014 release. ReCap is a separate application that enables you to create a point cloud project file (RCP) that references multiple indexed scan files (RCS). Those scan files can come from laser scanners, or even from a series of digital photos that you upload to the ReCap Photo online service.
After selecting the files to import, ReCap lets you adjust import settings that affect the size and appearance of the point cloud. The imported files are displayed in ReCap and can be modified before attaching the point cloud file to your AutoCAD drawing. For example, you can use tools to crop the point cloud to isolate a specific volume within the scene. After attaching a point cloud to an AutoCAD drawing, additional tools become available in AutoCAD that let you further adjust the point cloud. You can then use the point cloud to show existing conditions, or as the basis for constructing AutoCAD geometry.
Other Enhancements
Of course, like any release of AutoCAD, users will find a host of other, smaller enhancements designed to improve common tasks. For example, layers now use natural ordered sort, so that layers named 1, 4, 25, 6, 2 and 10 are sorted as 1, 2, 4, 6, 10 and 25 instead of 1, 10, 2, 25, 4 and 6. There’s also a new Merge option in the Layer Manager palette that enables you to select one or more layers in the layer list, merge the objects from those layers onto a different layer, and then purge the selected layers from the drawing.
Layers and linetypes from externally referenced drawings are no longer displayed in the linetype list of the ribbon or Properties palette, because you can’t control them from there. But externally referenced layers still appear in the ribbon and Layer Properties manager, so you can control their visibility. You can also now easily change the xref attachment type between Attach and Overlay, and change the path of selected xrefs between Absolute and Relative.
Rounding out the list of new features are several very welcome drawing enhancements. For example, you can now draw arcs in either the default counter-clockwise direction or clockwise by pressing the CTRL key. The command for creating single-line text now retains the most recent justification setting. When adding hatch or gradient fills, the program retains the most recent method for selecting objects to hatch (pick internal point or select objects). And when adding baseline or continued dimensions, AutoCAD can use either the current dimension style or the style of the selected dimension.
Autodesk continues to place increased emphasis on its suites, which provide some pretty good deals. For example, in addition to AutoCAD itself, the AutoCAD Design Suite Standard includes AutoCAD Raster Design, SketchBook Designer, Showcase and Mudbox for just $330 more than the cost of AutoCAD alone. The Professional suite adds 3ds Max to the mix, while the Ultimate suite adds Alias Design as well.
This time around, virtually all of the new features in AutoCAD 2014, including the intelligent command line improvements, live maps, Design Feed, drawing file tabs and Autodesk 360 connectivity, have also been included in AutoCAD LT 2014, the company’s lower-cost 2D-only alternative to AutoCAD.
Both AutoCAD and AutoCAD LT 2014 began shipping in late March, with the Design Suites following suit in April. AutoCAD 2014 supports Windows XP, Windows 7 and Windows 8 (including support for touch-enabled devices), but Autodesk has dropped support for Vista. AutoCAD 2014 also includes several new features to help improve software security, and prevent loading and running of unauthorized or malicious AutoLISP and VBA applications.
All told, Autodesk has once again done a great job improving its flagship product, making AutoCAD 2014 another very compelling release.

What is Overclocking


Introduction

Many people probably don't know what overclocking is but have possibly heard the term used before. To put it in its simplest terms, overclocking is taking a computer component such as a processor and running at a specification higher than rated by the manufacturer. Every part produced by companies such as Intel and AMD are rated for a specific speeds. They have tested the capabilities of the part and certified it for that given speed. Of course, most parts are underrated for increased reliability. Overclocking a part simply takes advantage of the remaining potential out of a computer part that the manufacturer is unwilling to certify the part for but it is capable of.
Why Overclock a Computer?
The primary benefit of overclocking is additional computer performance without the increased cost. Most individuals who overclock their system either want to try and produce the fastest desktop system possible or to extend their computer power on a limited budget. In some cases, individuals are able to boost their system performance 25% or more! For example, a person may buy something like an AMD 2500+ and through careful overclocking end up with a processor that runs at the equivalent processing power as a AMD 3000+, but at a greatly reduced cost.
There are drawbacks to overclocking a computer system. The biggest drawback to overclocking a computer part is that you are voiding any warranty provided by the manufacturer because it is not running within its rated specification. Overclocked parts that are pushed to their limits also tend to have a reduced functional lifespan or even worse, if improperly done, can be destroyed completely. For that reason, all overclocking guides on the net will have a disclaimer warning individuals of these facts before telling you the steps to overclocking.

Bus Speeds and Multipliers

To first understand overclocking a CPU in a computer, it is important to know how the speed of the processor it computed. All processor speeds are based upon two distinct factors, bus speed and multiplier.

The bus speed is the core clock cycle rate that the processor communicates with items such as the memory and the chipset. It is commonly rated in the MHz rating scale referring to the number of cycles per second that it runs at. The problem is the bus term is used frequently for different aspects of the computer and will likely be lower than the user expects. For example, an AMD XP 3200+ processor uses a 400 MHz DDR memory, but the processor is in fact using a 200MHz frontside bus that is clock doubled to use 400 MHz DDR memory. Similarly, the new Pentium 4 C processors have an 800 MHz frontside bus, but it is really a quad pumped 200 MHz bus.

The multiplier is the multiple that the processor will run at compared to the bus speed. This is the actual number of processing cycles it will run at in a single clock cycle of the bus speed. So, a Pentium 4 2.4GHz "B" processor is based on the following:

133 MHz x 18 multiplier = 2394MHz or 2.4 GHz
When overclocking a processor, these are the two factors that can be used to influence the performance. Increasing the bus speed will have the greatest impact as it increases factors such as memory speed (if the memory runs synchronously) as well as the processor speed. The multiplier has a lower impact than the bus speed, but can be more difficult to adjust.

Let's look at an example of three AMD processors:

CPU Model Multiplier Bus Speed CPU Clock Speed
Athlon XP 2500+ 11x 166 MHz 1.83 GHz
Athlon XP 2800+ 12.5x 166 MHz 2.08 GHz
Athlon XP 3000+ 13x 166 MHz 2.17 GHz
Athlon XP 3200+ 11x 200 MHz 2.20 GHz
Let's then look at two examples of overclocking the XP2500+ processor to see what the rated clock speed would be by changing either the bus speed or the muliplier:

CPU Model Overclock Factor Multiplier Bus Speed CPU Clock
Athlon XP 2500+ Bus Increase 11x (166 + 34) MHz 2.20 GHz
Athlon XP 2500 + Multiplier Increase (11+2)x 166 MHz 2.17 GHz
In the above example, we have done two changes each with a result that places it at either the speed of the 3200+ or a 3000+ processor. Of course, these speeds are not necessarily possible on every Athlon XP 2500+. In addition, there may be a large number of other factors to take into consideration to reach such speeds.

Because overclocking was becoming a problem from some unscrupulous dealers who were overclocking lower rated processors and selling them as higher priced processors, the manufacturers started to implement hardware locks to make overclocking more difficult. The most common method is through clock locking. The manufacturers modify traces on the chips to run only at a specific multiplier. This can still be defeated through modification of the processor, but it is much more difficult.

Voltages

Every computer part is regulated to specific voltages for their operation. During the process of overclocking the parts, its possible that the electrical signal will be degraded as it traverses the circuitry. If the degradation is enough, it can cause the system to become unstable. When overclocking the bus or multiplier speeds, the signals are more likely to get interference. To combat this, one can increase the voltages to the CPU core, memory or AGP bus.

There are limits to the amount of additional voltage that can be applied to the processor. If too much voltage is applied, the circuits inside the parts can be destroyed. Typically this is not a problem because most motherboards restrict the possible voltage settings. The more common problem is overheating. The more voltage supplied, the higher the thermal output of the processor.

HEAT!

The biggest obstacle to overclocking the computer system is heat. Today's high-speed computer systems already produce a large amount of heat. Overclocking a computer system just compounds these problems. As a result, anyone planning to overclock their computer system should be very aware of the needs for high performance cooling solutions.

The most common form of cooling a computer system is through standard air cooling. This comes in the form of CPU heatsinks and fans, heat spreaders on memory, fans on video cards and case fans. Proper airflow and good conducting metals are key to the performance of air cooling. Large copper heatsinks tend to perform better and the greater number of case fans to pull in air into the system also helps to improve cooling.

Beyond air cooling there is liquid cooling and phase change cooling. These systems are far more complex and expensive than standard PC cooling solutions, but they offer a higher performance at heat dissipation and generally lower noise. Well-built systems can allow the overclocker to really push the performance of their hardware to its limits, but the cost can end up being more expensive than processor to begin with. The other drawback is liquids running through the system that can risk electrical shorts damaging or destroying the equipment.

Component Considerations

Throughout this article we have discussed what it means to overclock a system, but there are a lot of factors that will affect whether a computer system can even be overclocked. The first and foremost is a motherboard and chipset that has a BIOS that allows the user to modify the settings. Without this capability, it is not possible to modify the bus speeds or multipliers to push the performance. Most commercially available computer systems from the major manufacturers do not have this capability. This is why most people interested in overclocking tend to buy specific parts and build their own systems or from integrators who sell the parts that make it possible to overclock.

Beyond the motherboards ability to adjust the actual settings for the CPU, other components must also be able to handle the increased speeds. Cooling has already been mentioned, but if one plans on overclocking the bus speed and keeping the memory synchronous to offer the best memory performance, it is important to buy memory that is rating or tested for higher speeds. For example, overclocking an Athlon XP 2500+ frontside bus from 166 MHz to 200 MHz requires that the system have memory that is PC3200 or DDR400 rated. This is why companies such as Corsair and OCZ are very popular with overclockers.

The frontside bus speed also regulates the other interfaces in the computer system. The chipset uses a ratio to reduce the frontside bus speed to run at the speeds of the interfaces. The three major desktop interfaces are AGP (66 MHz), PCI (33 MHz) and ISA (16 MHz). When the frontside bus is adjusted, these buses will also be running outside of specification unless the chipset BIOS allows for the ratio to be adjusted down. So it is important to know how adjusting the bus speed can impact stability through the other components. Of course, increasing these bus systems can also improve performance of them, but only if the components can handle the speeds. Most expansion cards are very limited in their tolerances though.

Slow and Steady

Now those who are looking to actually do some overclocking should be warned not to push things too far right away. Overclocking is a very tricky process of trial and error. Sure a CPU may be able to be greatly overclocked in the first try, but it is generally better to start out slow and gradually work the speeds up. It is best to test the system fully in a taxing application for an extended period of time to ensure the system is stable at that speed. This process is repeated until the system does not test fully stable. At that point, step things back a bit to give some headroom to allow for a stable system that has less chance of damage to the components.

Conclusions

Overclocking is a method for increasing performance of standard computer components to their potential speeds beyond the rated specifications of the manufacturer. The performance gains that can be obtained through overclocking are substantial, but a lot of consideration must be done before taking the steps to overclocking a system. It is important to know the risks involved, the steps that must be done to obtain the results and a clear understanding that results will very greatly. Those who are willing to take the risks can get some great performance from systems and components that can end up being far less expensive than a top of the line system.

For those who want to do overclocking, it is highly recommended to do searches on the Internet for information. Researching your components and the steps involved are very important to being successful.

the best operating system for gamming

Every gamer asks himself every now and then this question: Which is the best operating system for gaming? I’m here to answer that question.
The real battle is between Windows XP and Windows 7 but if you ask me there is no “best operating system”. Every gamer has different needs that can’t be satisfied by a single operating system. We have to compromise and choose the best that fits our needs as an individual.
Depending on what are our requirements the “best operating system” can be any version of Windows. If you want to play DirectX 9 games then the best choice is probably Windows XP but if you want DirectX 10 and DirectX 11 you must choose a newer operating system, Windows 7. But new isn’t always better, see Vista.
Many people say that Windows XP is dying or dead and I like to tell them that more than 30% of PC users still use it. Even though Microsoft recently stopped supporting Windows XP this doesn’t mean that it’s completely dead.
Best Operating System
As you can see, against popular believe, Windows 7 is actually better than Windows XP in DirectX 9 thus better for gaming! This time around new seems to be better. Windows 7 runs well even with older hardware making it king over other operating systems.
When it comes to DirectX 10 and 11 games there is absolutely no competition whatsoever. Because Windows XP only has support for DirectX 9 there is clearly one winner: Windows 7.
Further more, Microsoft stopped supporting Windows XP thus making Windows 7 prone to improvements…
If you’re not sure what architecture of Windows 7 to choose, x64 or x86, read this: Most hardcore gamers choose the 64bit version of Windows because it supports more than 3 GB of ram and is more stable / reliable.
40% of gamers on Steam use Windows 7 Ultimate x64 and more users make the move to x64 every day. In contrast, only 20% of Steam users have Windows XP x32/x64 installed.
All we can hope is that Windows 8 will take 7′s throne on release date but something tells me that Windows 7 will be the best operating system for many years to come or until DirectX 12 is released.

Best Operating System for Gaming is: Windows 7 x64
