<label xml:space="preserve"> - Allows to separate different contour types by colors

- Finds overlapping / collinear / (self-)intersecting

|

- Works with paths which have Live Path Effects (LPE)
|
||||
|
||||
Tips:
|
||||
- If nothings is selected, the whole document will be processed, regardless of groups. In contrast, if you made a custom selection, check to handle or not to handle groups.
|
||||
- Convert your strokes and objects to paths before
|
||||
- Does not work for clones. You will need to unlink them before
|
||||
- Use extensions to filter short/unrequired paths
|
||||
- Use extensions to purge or repair invalid paths
|
||||
- Use 'Path > Simplify' or hit 'CTRL + L' to simplify the trimmed result. With a fine quantization setting the simplified paths will be nearly identical to the original path (except the position of control points)</label>
|
||||
<label appearance="header">Do not select too much paths at once if you have got a fine settings for quantization. This extension is slow and might calculate hours on ultra high configurations.</label>
