<flip214> When I create a box (rectangle extruded, smaller rectangle as difference extruded) and then try to put a few crossbars in, the crossbars stay white lines on extruding and have no volume - and no faces.
<flip214> How can I fix extruded regions to become volume?
<whitequark> crossbars?
<whitequark> can you show a screenshot?
<flip214> whitequark: just some raised areas to strenghten the flat surface
<flip214> one sec
<swivel> after you extrude the cube, you'll have to sketch the crossbars on the face in 2d and extrude those independently, i imagine
<whitequark> yeah, that sounds right
<whitequark> you can't extrude faces, anyway
<flip214> whitequark: https://ibb.co/W6FWF3s
<flip214> swivel: that's what I did
<flip214> I created rectangles and connected them ("point on line") to have no loose ends
<flip214> No naked edges, no interfering parts, etc.
<whitequark> can you share the sketch?
<flip214> send me your mail in a pm
<whitequark> whitequark@whitequark.org
<flip214> ah, okay
<flip214> one sec
<flip214> take your time, I'll be off for now... reading mails and backlog tomorrow. Thanks a lot!

<whitequark> flip214: ah, so the issue here is that you have a lot of coincident edges
<whitequark> this confuses the geometric kernel
<_whitenotifier-f> [solvespace] phkahler commented on issue #77: Parametric sketches - https://git.io/JfQq5
<whitequark> if you remove all the "crossbars" from g008 and draw a bunch of polygons not connected to existing lines, this gets better

<flip214> whitequark: how did I get these coincident edges? What did I do wrong?
<whitequark> you drew one edge of a crossbar (long rectangle) over the edge of a post (small square)
<flip214> so I shouldn't have used rectangles there but simple lines?
<flip214> ack, thanks a lot!
<whitequark> that wouldn't work either
<whitequark> since then it wouldn't be a closed contour
<flip214> well, I could make lines from the border to the post's corners
<whitequark> you'll need to split each edge of the square into three segments (for example) and mark the central one as construction
<whitequark> yeah, something like that
<flip214> ie. don't have the posts bigger than the helper volume
<flip214> ack, understood
<whitequark> that would also work
<flip214> I also tried with full-length rectangles that cross each other, and then splitting up where they cross
<flip214> but that just produced other problems (duplicate edges) and didn't result in a volume, too
<whitequark> I think that should work, in principle
<flip214> well, I guess I had an error somewhere
<flip214> never mind
<flip214> thanks a lot!
