Crash on cq.Solid.extrudeLinearWithRotation()
To Reproduce
While working on the creation of a thread library I discovered that cq-editor crashes on extrusions with rotation and was able to reproduce the problem with the following (note that FreeCad is able to open the generated step file which looks surprisingly good for such a rough approximation) :
import cadquery as cq
# Create a rough approximation of the perimeter of a cross section of a M3-0.5 screw
outer_wire = cq.Workplane("XY").circle(1.5).translate((0.2, 0, 0)).wires().val()
print(f"Is outer_wire valid? {outer_wire.isValid()}") # True
thread_length = 5
# Extrude the wire back into thread
thread = cq.Solid.extrudeLinearWithRotation(
outerWire=outer_wire,
innerWires=[],
vecCenter=cq.Vector(0, 0, 0),
vecNormal=cq.Vector(0, 0, thread_length),
angleDegrees=360 * (thread_length / 0.5),
)
print(f"Is thread valid? {thread.isValid()}") # True
# Let's see what it looks like
cq.exporters.export(thread, "thread.step")
# What does cq-editor see?
if "show_object" in locals():
show_object(outer_wire, name="outer_wire")
show_object(thread, name="thread")

Hi, I tested this script. I see that CQ-Editor memory usage continues to increase until process exit.
CQ-Editor was able to display the part after increasing the Deviation value in 3D Viewer settings: Deviation: 0.01 Angular deviation: 0.1
The very large memory usage case for me was with default Deviation 1e-5.
Thanks! When I change Deviation to 0.01 my "real" threads are visible in cq-editor again. I'll put a note in the documentation for my thread library that this value should be changed. Is the only downside a slight drop in viewing fidelity?
Cheers, Roger

Yes, I think that's right - it should be a render issue. The trace, while this is running, is in Tessellate, and @adam-urbanczyk mentioned increasing Deviation when a similar render problem came up in discord.
A few test results:
| Deviation | Time | RSS peak |
|---|---|---|
| 1.5e-5 | ~1m45s | ~8.3GB |
| 2e-5 | ~45s | ~5GB |
| 1e-4 | ~10s | ~1.4GB |
| 1e-3 | ~5s | ~1GB |
Wow, that;s a big difference. I've used ray tracers that render pixelated images to start and then recursively refine the image to eventually get to the final result. If the same was done here those first few loops would take relatively no time at all.
Thanks for the help, Roger
