I try to coding for a circular column.thschrader wrote: ↑Mon Jul 10, 2017 8:28 am@chakkree:
At first: I have no programming-skills, my comments are only from a user point of view.
chakree, Im looking exactly for a possibility to draw rebars partially outside the beam,
like shown in your picture. Is that implemented in the actual FC17 dev-snapshot?
Please have a look at
https://forum.freecadweb.org/viewtopic.php?f=13&t=23349
short translation of my german text:
I want to draw rebars in an circular concrete column. If I draw a circle at the top
of the cylinder (in rebar-mode), I get an error. So I used a polygon and "rounded" it.
To produve the vertical radial-bars, I constructed a prisma as a help for attaching
the vertical rebars.
Greetings thomas
