Why did this drawing suddenly bring QCAD to its knees?
Posted: Fri Mar 08, 2019 3:16 am
QCAD Pro 3.21.3.0
Xubuntu 18.04.2 Linux 64-bit
I'm just a QCAD putzer and I was intrigued by Husky's twisted wire drawing (in another topic) so I decided to try it. I got as far as a drawing with eight splines and four straight lines, on two layers. Then suddenly QCAD bogged down to a crawl. While my drawing may not be optimal, 12 objects isn't a lot. And it's just this drawing - Doing almost anything triggers a LOT of CPU but other drawings are fine.
For example, here's a CPU graph when I switched to it from another drawing:
...and here's one when I hid a layer:
Zooming is slow, etc., but saving is quick (although loading is slow). I had another drawing open as well and it's very quick, perfectly normal. Switching to other drawings is fast, but back to this one is slow. I cleaned it - No duplicate nor zero-length entities. Restarted QCAD, etc. No better.
The drawing is attached - What did I miss?
Thanks.
