System information

SolveSpace version: 2.3~7c1ca460

Operating system: Windows 10

Expected behavior

Design exported as an stl file, or step file or as a graphic in a pdf file.

Actual behavior

solvespace.exe runs at high cpu rate for a while.
"(Not Responding)" shows on title bar if app window is clicked while running.
Then Windows pop-up announces "solvespace.exe has stopped working".

Additional information

In the case of step or pdf output, there is a zero-byte file.
For the stl option, no output file is created.
Export as .png finishes correctly.

Design is intended for 3d printing.
Design starts with a sketch, lathed, then differenced with an extrusion to keep only a portion of the lathed object.
Full-circle lathed object exported as an stl, but was too large to print.
"Force NURBS surfaces to triangle mesh" options didn't correct the problem.

I deleted the extrusion and created a new extrusion of the same form starting on a workplane below the lathed part and then extruded to a plane above the part. This exported without any further issue.

I can confirm this is present even with the fix for #259.

@Evil-Spirit Looks like the export is spending a lot of time in SEdgeList::CullExtraneousEdges, any ideas?

May be BSP tree overflows stack when performed triangle booleans or hidden line remove?

i'm guessing this is getting me too, I created a simple file then closed, and now it hangs at open with "Not Responding". Is there a tmp file somewhere or where is the last-open-file saved? I didn't even save my work.

See configuration → autosave interval. The next time you open the same file, you'll get prompted for whether you want to load the autosave.
