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.
Why did this drawing suddenly bring QCAD to its knees?

Here we go .... understood .... my fault .......
I checked your drawing on my Win10 and I can't reproduce a crash. Then I bloated it with many copies ....
.... which slows QCAD down but it is still stable. CPU (2 Cores) stays below 38%.
BTW: Your drawing looks already pretty good!

Re: Why did this drawing suddenly bring QCAD to its knees?
It's the very fine dash-dot pattern of the red splines. Change the linetype of layer "red" to "continuous" or adjust the lineweight or linetype pattern scale or switch to screen-based linetypes (View > Screen-based Linetypes).
Re: Why did this drawing suddenly bring QCAD to its knees?
That was it. I created the drawing from my standard template and that layer was originally for center lines, hence the dashed line. The actual scale of the drawing (which I was going to reduce once done) made it so large I didn't notice the linestyle. Changed it to Continuous and all is well.
Excellent - I was at least relieved to see it was the drawing and not something in QCAD itself. Obviously Husky's computer is much faster than mine (which is admittedly a few years old).
Thanks.
