Sweep did not produce meaningful result

[jmturner]

I'm working on this project for school. It is basically a frame for a small golf-cart-truck thing... long story. The frame is designed to elimante as many welds as possible and be bent on a CNC bender. Anyway I created this 3D sketch from a few 2D sketches and a 3D curve, which was much easier than trying to make it from a 3D sketch alone. I'm trying to sweep the pipe profile around the path. The first section works fine, but when I try to add the splines at the end, it gives me a "did not produce meaningful result" error. The preview works fine and looks great. Is there some way to fix it? Thanks in advance for the help!

Hi Jared,

Thanks for posting your part, looks like you've found a bug! I've logged 37656 for the failing sweep.

I'll be back in touch soon, hopefully there's a workaround.

Cheers,

Indy

Hi again,

Looks like the curvature in Sketch8 is too high for this particular profile. Here's the high curvature area:

If you take a look at the curvature of sketches (activated by right-clicking on a curve and selecting "Display Curvature") you can usually get a good idea of the trouble areas. For instance, here's what I saw in the bit I mentioned above:

I reduced the curvature by pulling the handle in Sketch8, circled with the direction below:

The difference is subtle (and I'm not sure why the curvature 'comb' changed from green to blue) but here's how the 'comb' looks after my edit:

I was able to create the sweep after doing that:

Hope this helps but feel free to shout out!

That makes sense, thanks for looking into it!
