3d Sweep Fails at bends on new computer

[Mech.Mon]

Hello All,

I am trying to verify my tubing points on a 3d Sketch. I created the a using points and lines. Verified the tubing would work in the model, extracted the points, normalized, translated back to the origin, and rebuild the tube using the "new" points. This is the way that I have always done tubing, however I recently moved to a new computer. There must be some different setting that was set on my old computer, that isn't set on this one, but I cannot find it.

I've tried putting the points in one at a time, importing from excel, larger/smaller tube diameter, larger/smaller bend radius. Either way, the bend won't go past the bend.

It seems the problem is with the 3D line:

When I select the 3D curve as the path for the sweep, the entire line pre-highlights as I would expect it to. However, if I select a segment, it appears there is a discontinuity lin the line. I added the tangent constraint, but haven't gotten any further along.

Would you be interested in an entirely different technique?

Post it anyway.

A day that you don't learn something new, is a wasted day.

Hi! This is a known issue starting from 2013. Basically, Sweep command does not properly recognize a path with degenerated point (the point between the two quarter arcs). Currently, you can edit the Sweep and then pick the rest of the segments one by one consecutively.

Thanks!

Well that works, however the Part 2 was created in Inventor 2014 with the exact same method. Odd.

@JDMather, I would like to see this method. Is it backward compatable?

That is why I asked - I will have to create a bunch of images for you to follow as I don't have 2014.
