See how the latest AutoCAD LT 2D CAD software helps you create 2D drawings. Available for Windows and Mac. Monitor current system variables against a preferred list of values. Notification balloons alert you of deviations. You can try AutoCAD, AutoCAD for Mac, or any of the industry-specific AutoCAD toolsets to see how they can speed. Contains a list of system variables and provides access to view and change the values as needed. Monitors system variables and reports when they are changed from their preferred value. In most cases, this happens when a custom routine is cancelled. If you are going to do some customization in AutoCAD, then it’s unavoidable that. I’m not good in customization. So having a system variable list is very helpful. I know there are some websites provide this list. But some of them are for old version of AutoCAD. Some of the sys var might already have been removed. Some might have been changed. Bank of america download app. And if you use old version of AutoCAD, it might not even existed yet. Why not you try to look inside your AutoCAD? If you are not familiar with system variables, they are the variables that control your AutoCAD behavior. Every options you save, current layer, color, or lineweight, etc. For example, we can turn on/off object snap by pressing [F3] – if I’m not mistaken it was not F3 before, right? But if you are creating a new command like in or, let’s say you want to turn off OSnap temporarily, you’ll have to use system variable. You can change the SNAPMODE value to 0 (off) or 1 (on).

You can use CLAYER to control the current layer. There are a lot of things you can control by using system variables. So how you can see the whole system variables? Using SETVAR Just type SETVAR [enter] then type? Enter once again to see the whole list. You need to press [enter] several times to see them all. Command: SETVAR Enter variable name or [?]:? ![]() To improve AutoCAD performance you can related to the operating system and your hardware. But apart from making these changes, there are also some default settings which can be changed using system variables to visibly enhance the performance of AutoCAD. ![]() In this article, I have listed fourteen such system variables. ZOOMFACTOR This variable will change the speed with which scroll wheel of the mouse will zoom the drawing area. If you are a beginner then try to change the ZOOMFACTOR variable to 30 range which would be easy for you. The Default value is set on 60 which will be suitable for most of the cases but if you want more speed you can change this variable to 100. WHIPTHREAD This variable specifies how AutoCAD will use additional processors on the machine. If there is only a single processor then this variable will not have any effect. The default value of WHIPTHREAD system variable is 1 but you can change it to other values as well. 0 – No multithreading used 1 – Regeneration only is carried out by multiple processors 2 – Redraw only is performed by multiple processors 3 – Regeneration and redraw carried out AutoCAD can use that extra processor to improve the speed of operations such as zoom which redraws or regenerates the drawing. There will be a slight acceleration when you are working with large drawings if you set this variable to 3. But you should not expect a drastic improvement in the performance just by changing this system variable. TOOLTIPS This variable is set to 1 as default which will show tooltips when you hover your cursor over a tool. To improve the performance you can turn off these tooltips by changing TOOLTIPS system variable value to 0. Tooltip on circle EXPERT The EXPERT system variable will suppress certain prompts and instead it will take the default value YES as the input. The default value of this system variable is 0 but you change it as per your requirement. 0 – No suppression of prompts 1 – Suppresses “About to regen, proceed?” and “Really want to turn the current layer off?” prompts 2 – Suppresses prompts of variable 1, “Block already defined. Redefine it?” and “A drawing with this name already exists.
