The default value of PEDITACCEPT system variable is set to 0 which allows Polyline Edit command to return a prompt as shown in the image below. When a prompt is suppressed by Expert option the prompt will automatically take your input as Yes. Overwrite it?” prompts.ģ – Suppresses prompts of variables 1, 2 and prompts issued by LINETYPE command.Ĥ – Suppresses prompts of variables 1, 2, 3 and prompts issued by UCS save and VPORTS save options.ĥ – Suppresses prompts of variables 1,2,3,4 and “That name is already in Use, redefine it?” prompt. Redefine it?” and “A drawing with this name already exists. The default value of this system variable is 0 but you change it as per your requirement.ġ – Suppresses “About to regen, proceed?” and “Really want to turn the current layer off?” promptsĢ – Suppresses prompts of variable 1, “Block already defined. The EXPERT system variable will suppress certain prompts and instead it will take the default value YES as the input. To improve the performance you can turn off these tooltips by changing TOOLTIPS system variable value to 0. This variable is set to 1 as default which will show tooltips when you hover your cursor over a tool. There will be a slight acceleration when you are working with large drawings if you set this variable to 3.īut you should not expect a drastic improvement in the performance just by changing this system variable. The default value of WHIPTHREAD system variable is 1 but you can change it to other values as well.ġ – Regeneration only is carried out by multiple processorsĢ – Redraw only is performed by multiple processorsĪutoCAD can use that extra processor to improve the speed of operations such as zoom which redraws or regenerates the drawing. If there is only a single processor then this variable will not have any effect. This variable specifies how AutoCAD will use additional processors on the machine. 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. If you are a beginner then try to change the ZOOMFACTOR variable to 30 range which would be easy for you. This variable will change the speed with which scroll wheel of the mouse will zoom the drawing area. In this article, I have listed fourteen such system variables. 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. To improve AutoCAD performance you can tweak some settings related to the operating system and your hardware.
