Hello,
I would like to draw a line (and generally work) with a irrational length, like sqrt(2) or etc. Is it even possible?
For example - now I am trying to round this edge and I know that I need to have 4 mm thickness in the narrowest spot (see img). This was everytime pain to me to do something like this, commonly I was doing it like “eh this look good, lets connect the ends to the surface and it will somehow works” (I am (trying to make :D) making models for 3D print, so minor errors and imperfections are not an obstacle). Now I know where have the ends of e.g. 2 arc function but I don’t know how to measure it and ,deposit".
One rather simple way is to use the ‘Tape Measure’ tool inside a group.
Isolate (or copy to the side) the relevant edges (both legs), the circle, etc. of the current situation to have them in a separate group. Now inside the group measure the distance A-B and type 4 and answer the question about resizing the active group or component with yes.
Finally I can do this rounding precisely and normally
