Drafting software like AutoCAD provides designers a way to build models in both 2D and 3D. This allows engineers and product manufacturers a way to create technical drawings such as wire frame with ease. A slow or jumpy cursor is a problem that can occur with the AutoCAD software. It may be related to the software settings, or it may be an issue with the hardware on your computer.
Snap works on a grid to keep everything on the same line when you draw in AutoCAD. In other words, when you position individual components on a horizontal or vertical plane, they will line up without your having to manually place them. Snap can sometimes make the cursor appear to jerk or move differently. AutoCAD allows you to toggle Snap on and off by pressing the "F9" key. If you find the cursor is moving slow, try pressing F9 to see if Snap is causing the issue. Being able to detect when Snap is on takes some practice as the software does not provide a sign. After awhile, you can tell by the way the screen reacts to your drawing and how the pointer moves that Snap is enabled.
Selection Cycling is a feature you need if you are working in multiple layers. For example, if you were using AutoCAD to design a car, the seats would be on a different layer of the drawing than the doors. Selection cycling allows you to work on the seats without changing anything on the doors even though they overlap. If your project is large and contains multiple layers, Selection Cycling can slow the cursor down as you move. If also takes up program resources unnecessarily if you are not working in layers or using the function. For these projects, use the Software menu to turn off Selection Cycling. This should improve the speed of your cursor.
Turn off Features
AutoCAD can take up many of the resources on your computer. This slows down the other functions, so the computer seems boggy and the cursor becomes sluggish. Turning off some AutoCAD functions you do not need is one way to reduce the pull the program has on your system. Examples of programs you can do without include Quick Properties, Dynamic Input and ToolTips, states professional IT firm IMAGINIT Technologies in their blog. The Software menu system should provide options to turn the features on or off.
AutoCAD requires appropriate hardware to function properly. If the pointer is sluggish, this may indicate that your computer hardware is struggling to run the application. This is especially true for the graphics card and driver, explains IMAGENIT. For example, having a poor quality graphics card or a out of date driver may be enough to cause a problem. Autodesk, the manufacturer of AutoCAD, offers a list of graphics hardware and drivers appropriate for its software package. Checking what you have on your computer to what they suggest may give you some clue to the problems caused by hardware that is not compatable with AutoCAD.
