Issue encountered with draft projection in Techdraw
I encountered this issue while testing out Techdraw. When inserting the following drawing using the Techdraw Insert Draft Object, the results is as follows. I've also shown how the drawing was supposed to look like:
It appears the problem is with the arc lines, both arc and fillets.

Re: Issue encountered with draft projection in Techdraw
I've never seen this one. Is it possible to post the FCSTD file? What happens if you use NewView instead of Insert Draft Object?

Please see attached the file.
I've made a compound and simple compound, and they seem to show up fine in the drawing. By selecting them and using New View.
I've tested with a simple arc, and they also show up in a way they are not supposed to.

Re: Issue encountered with draft projection in Techdraw
Yes indeed i am familiar with that same problem, I have come accross it serveral times without being able to understand what is causing that.
There is something wrong with the way techdraw renders arch, be it draftwire 2D archs or generated archs from 3D objects with fillets, etc. in my case the door swings, and the corners of sinks etc.

Re: Issue encountered with draft projection in Techdraw
This is strange that it internally uses the same OCC algorithm in all cases...
Can you guys test something when you have a chance? Make a same view of an Arch section pane in TechDraw and in Drawing, to see if we have the same problem in both.

Re: Issue encountered with draft projection in Techdraw
I'll try to test a few more cases when I have the chance, see what sort of tools/conditions reproduces it.

Re: Issue encountered with draft projection in Techdraw
Is working plane part of the problem? If I change the Direction of the DraftView to (1,0,1), the giant arcs disappear.

Re: Issue encountered with draft projection in Techdraw
Inserting "Group" using Draft "PutOnSheet" seems to work.

Re: Issue encountered with draft projection in Techdraw
Draft "PutOnSheet" is inserting a Drawing workbench page, not a Techdraw page no? I can confirm Drawing / Drawing Dimensioning inserts the objects just fine. It's Techdraw's thats giving the problem.wandererfan wrote: ↑Tue Jun 13, 2017 5:12 pm Inserting "Group" using Draft "PutOnSheet" seems to work.
I drew some arcs & fillets, and then inserted them via Techdraw again, and it got jumbled up. I tested on Windows and it shows up the same way.
Re: Issue encountered with draft projection in Techdraw
I tried something similar. I drew in Sketcher and converted to draft. While it looks better than yours, the arcs are, well, not perfect yet. I cannot select elements in TechDraw to add measures.
