Issue: 

By default, a clipping border will be displayed after clipping a block. How can this border not be displayed in ZWCAD?

Solution:

The system variable XCLIPFRAME or FRAME controls whether the clipping frame is displayed.

Enter the command XCLIPFRAME, set its value to 0 and the block clipping frame will not be displayed.

Please note that it can also be set with the FRAME system variable.
