[BUG] Closed sketch curve does not show profile.

[gscotti]

This is a spline curve, but profile is not showing up correctly. My guess is because sketch's reference plane is exactly bounded by these points and Autodesk's algorithm messes it up.

Hi @gscotti,

Thank you for sharing your sketch and the pictures.

I could see that the spline is showing the correct shape but it is not showing the spline in the sketch.

If you move a single "Control point" just along the grid, you see that the spline appears again, click Ok and move it back.

You will see that the spline appears as usual.

I will get in touch with the development team and check with them what could have caused the disappearance.

I hope this helps.

Thanks,

Hi @gscotti 

When I edit sketch 3 and delete the spline then there is something else there. After I have deleted everything in the sketch (which takes a number of steps - there is something funny going on there) and then project the 4 corner points of sketch 2 and then redraw a similar spline all is well.

I would like to suggest simply deleting sketch 3 and re-doing it.

Hope this helps.

Regards

John

Points were added programmatically (python script on the API).

If you open that file again, edit the sketch, add an offset to the curve and it's fixed.

For that reason I believe there's something to do with parametric reference plane having its domain restricted. (A regular plane has an infinite domain).

Hope that helps.

That does explain it better. But I am still curious as to what the other "artifacts" in sketch 3 are. Any ideas?

Hi,

Thanks for reporting the issue. Meanwhile, I'd suggest using 4 splines as edges instead of one spline as a loop.

[gscotti]

The artifacts is because the curve is a spline. You can tell where the endpoints meet, because the artifact is not there in one of the corners. That's totally understandable and somewhat expected.

Apollogies, I meant to ask what are the artifacts remaining after deleting the spline?
