Either all xclipped blocks or xrefs (after being bound) in a drawing can be cleaned or you can clean them one by one.

With XClipClean you can clean your xclipped blocks from everything that is outside the boundaries of the block.

Start with the command XCC to clean a selected block. You will then be prompted to select a block that is xclipped. The block will be saved to a temporary file during this process.

Use the command XCCAB for XClipClean All Blocks.

To do the cleaning without exploding nested blocks use the XCC1 or XCCAB1 commands.

XClipClean was built to solve some specific requirements and thus there are cases where XClipClean does not work well or at all. Nested clipped blocks are not handled. Inverted clipped blocks are not handled. It might be possible to modify the code to handle these cases but the work might be more than the gain.

SDI set to 1 is not supported. SDI must be set to 0.

HIGHLIGHT variable may be set to 0 if the app fails and you need to restore it to 1 manually.
