How to fix Unresponsiveness and Delays in AutoCAD.

Lags and delays can break down even the most resilient among us, and 30-second delays in AutoCAD are a big storm to endure in the face of tight deadlines and project workflow. These responsiveness isssues are often a result of pressing the F8 (Ortho) function key, as we’ve observed in recent cases.

The most effective fix across the board for most users was TEMPOVERRIDES, a system variable that turns the temporary override keys for the drawing ads on and off–such as Ortho mode, object snaps, or Polar mode. If you wanted to use Ortho in the middle of the Polar mode, for instance, holding down the shift key would temporally activate Ortho mode. Once the shift key is released, the Ortho mode will be turn off and it will return back to Polar functionality.

If you wanted to temporarily turn off all of the running osnaps, you could hold down the F3 key until you wanted all running object snaps to be resorted. There are also several temporary override keys that are available for specific running object snaps.­­­ The keys in the following illustration are the default keys, but you can change key assignments and add your own as needed.

While temporary overrides are very useful in everyday workflows, most people don’t use them or are even aware of them. Most users experiencing the delays when using this built-in functionality were able to fix the problem by deactivating this function by turning the OFF (0) the TEMPOVERRIDES system variable in AutoCAD.

It is always a good idea to make sure that you are running “way above” the minimum system requirements according to the Autodesk website. And always make sure to have all of your service pacts and updates installed for your software, as well as your operating system (OS).
