New-ish onshape user- trying to figure out why my loft isn't working.

ebuzzmiller

I am currently trying to make a model of a foot by lofting together shapes on different planes, however it seems not to be working, and twisting instead of having smooth curves. I have tried literally everything from changing the guide curves to the path, etc. but nothing seems to make it work. If anyone has any suggestions on how to fix this problem; I was looking online to figure out how to make all the lines one but it seems no solution exists. If anyone has any idea why it isn't working please let me know!!! I'm including a screen capture of my drawing. Thanks!

Your loft is twisting because the number of points on each profile is not consistent, try adding/removing points from the profiles to get a smooth loft. I would also encourage you to take a look at our video library and help documentation for more information about different features within Onshape

I suggest matching vertices, having more guides, or doing one section at a time instead of one big loft.

I would also recommend ensuring that your guides pierce the outer edge of each profile. If they do not touch the edge of the profile, the loft will fail.

Thank you all!
