How to extend an arc

I am using 5.520.6147.0 #9d8cd91e on a Windows PC.

I have an arc that needs to be extended to meet another line. I do not see a way to maintain the diameter of the arc while extending the arc manually by dragging the endpoint. When I click on the arc, the purple guideline that appears has the same radius as the arc I am trying to extend, but as soon as I click on the point to move it, the purple guideline changes to align with the X-Y plane and when I drag the point the diameter of the arc changes.

Hi Jeremy,
Try this:

  • lock the line
  • select endpoint of arc
  • select coincident method

Hey Bob,

Well duh! That is the hardest part of swapping between AutoCAD, Sketchup and Shapr3D…the constraints. Your tip worked perfectly.

Great! I’m glad I could help.
