I'm trying to make rectangular shape in sketcher with rounded corners. Here is workflow:
1) Make rectangle of any shape and dimensions with "Create rectangles" tool, it additionally adds vertical and horizontal constrains to lines
2) Round all four corners with "Fillets" tool
3) Constrain rounded corners with same 2mm radius with "Constrain arc or circle" tool (result in pic. 1)
3) Add symmetrical constrain between two points of opposing lines and axis between them (pic. 2)
And after adding symmetrical constrain something happens that I can't understand: constrain added and working like i expect it, but one of the four fillet radius constrains disappears (pic. 3). It still indeed 2mm radius, but when i try to reapply radius constrain it shows in dialog window that radius is still 2mm (pic. 5) but when hitting "OK" error message pops up (pic. 6).
It all constrained and i can continue sketching, but it makes me think i'm doing something wrong way. Help me pls) Thanks in advance!
