help with noob freecad problem
« on: July 03, 2021, 01:11:40 am »
See screenshot. I created a clone of a curved line, ran it parallel to the original and a vertical line intersects it. I want to join the vertical at intersection and remove the leftover bits. It's probably really simple but because I find it hard to get a handle on the nomenclature I don't know what to search for.

CAD and 3D programs generally share common mechanisms for design.  Where two 'lines' join is called a vertex.  Multiple vertex are referred to as vertices.  A vertex or vertices are objects that can be added to a line/spline/segment to subdivide it and or add connection points.  I don't use freecad but the concepts will be similar. To join the two lines at the intersection:

Add vertices to both lines at the intersecting point, weld the vertices together and delete the unwanted segments.

Thankyou! Cutting and pasting that into my CAD notes do I don't forget ☺️

Not sure I understand correctly, but if I do, it's a very simple operation and present in most CAD software.

Check to see if this is what you are after:

Thanks guys. I will check tonight but that curved line I made with the b spline tool. I think I may have read somewhere that freecad has some issues with that function.

According to that page, the B-spline limitation only affects v0.18 and below.  If it doesn't work, I'd try the latest version and see if it has been fixed.

definitely something to do with B spline. If I create simple overlapping lines in a test sketch it works fine. see pics
