Hi Kunda1,

I have tried to document the feature a bit, however I am quite a Wiki beginner, so it may not be according to the common expectations. I have also added the item to Sketcher Workbench Geometries commands overview, however I do not know what these <!--T:xxx--> HTML comments mean, so I rather skipped adding such a line.

Kind regards,


Tomas

Don't worry about the formatting, we can fix that.
The <!--T:xxx--> stuff is the translation addon for the wiki. Don't mess with those unless you know what you're doing.

Just a quick note and risking cluttering up this thread but had to say "Yay!!! Thanks for the function!" I just got aware of it when I recently downloaded the 0.20 weekly build. Will be using it ALL the time based on my workflow (or lack of organization when sketching :lol: )

Hi,
It would be great if one could select an existing point instead of creating a new one.

Can you elaborate how it should work?

Current behaviour:
Selecting the "Sketcher Split"-function lets you add a new point on an existing line. See also https://wiki.freecad.org/Sketcher_Split

New behaviour:
Selecting an existing point on an existing line and thereafter selecting the "Sketcher Split"-function does use the existing point for splitting the line similar to the newly created point from the current behaviour.

Right, I was also thinking about this. It would make it possible to split lines precisely using properly constrained points attached to them.

Some thoughts to be considered:
- Should it split all lines on which the point lies?
- What should happen if a point has a point-on-object constraint on a line, but is not lying on the line itself, but on its extension?
- Is a point being symmetric to the ends of a line considered to lie on the line (I think so)?
- point-to-line tangency should be respected
- point-to-line orthogonal should be respected
Are there more such cases?
