Any advice would be most welcome please see screen shot attached. This is a plan showing some curved lines in 2D. How do I go about dimensioning them? Is it possible? I know how I can dimension arcs and circles but these irregular lines have me stumped. Thanks in advance.

Can anyone advise how I create this lozenge shape in VW2017. I tired drawing a 2D version of a rounded corner rectangle - extract - and then use Fillet Edge, it won't work. Please see image I would like to create thank you!
