Draft: Fix dimensions of parametric circles

Post by nizovn » Sat Oct 21, 2017 1:39 pm

I'm new to FreeCAD, using it since this week. I find it very useful and it satisfies my needs (paramentric drawings). Thanks a lot for this project!
However, there is one bug (or maybe it's just my misunderstanding how tool should work) which is very important for me: parametric dimensions in Draft Workbench for curved edges doesn't work correctly.
For example, these are simple commands which create cylinder and dimension of it's diameter:

Code: Select all

import Draft
This is the result:

You can see that resulted dimension line is orthogonal to cylinder's edge, and such dimension is not useful.
So, I fixed this behavior, and after these changes (see below), the result looks as expected:
