CAD hot tips: how to go back to a special step after overusing UNDO?

UNDO is useful to cancel the mistake and go back to the right state, we can use Ctrl+Z or command UNDO to make it work in ZWCAD. But sometimes you might overuse it and want to go back to a special step, how?

Input command MREDO and then input the step that you want to restore. This command is used to reverse the effects of several previous UNDO or U commands. Besides, you can also use Ctrl+Y to go back step by step.

CAD tips: File extension SV$, what is SV$? How to open SV$ file?

Issue:

After using ZWCAD for a while, you find there are some file with SV$ as extension in your folder. What is this file? How to open it?

Solution:

The SV$ file is automatically saved DWG file. If you start the automatic save option, your drawing is saved at specified time intervals. By default, system assigned the name filename.sv$ for temporarily saved files, filename here refers to current drawing name.

The temporary files are removed automatically when a drawing closes normally. However, these files are not deleted if there is a program failure or power failure. You can recover the drawing by reverting to a previous version of your drawing from the automatically saved file. In order to do that, you have to rename the file using a .dwg extension. You can find SV$ file from “C:\Documents and Settings\Administrator\Local Settings\Temp”
