Can you highlight them?

Thanks!

Can you highlight them?

If you see the first picture above, the hidden seam from the radius is visible.

Sorry for my lack of education on this topic. So if the radius is visible it means this bug is no more, correct?

I believe user1234 was talking about the edges I highlighted in yellow from his first capture.

These are hidden edges that should not be visible. But as I wrote in another similar bug/topic, the Drawing workbench will be deprecated in favour of TechDraw. If TechDraw no longer shows the bug, we should consider fixed.

Sorry for the loooong delay and that i false worded that.

If you took a file, that was made with 0.16.XXXX, and make a drawing with 0.17.XXXXX TechDraw, it makes a false smooth visible edge (the invisble is visible).

But if you make a complete new model with 0.17.XXXXX and make a new drawing with TechDraw with that, it works perfect.

Solved? I am not allowed to say that. I would prefer yes. But i am not a developer.

Sorry for my bad english.

Now that's puzzling.

I wonder what @wandererfan makes of this?

I still haven't managed to find time to compile OCC 7.1.0 to test this myself.

[triplus]

Issue report was related to arcs not showing correctly and that was resolved in OCC.

But if you make a complete new model with 0.17.XXXXX and make a new drawing with TechDraw with that, it works perfect.

If this wouldn't be correct new issue related to hidden line removal would make sense. But as you say it works correctly in TechDraw in your test. Therefore no new issue needs to be reported for now. And if such issue would be detected it wouldn't be related to issue #2354.

Beats me. Definitely have a hidden smooth line getting returned as a visible smooth line using the original model. I made a vaguely similar sketch using 17/7.0.1, rotated it and my hidden lines were fine.
