Create a fit spline on yz plane and project onto xy plane. The points do not line up. There shouldn’t be any way for me to screw this up. the vertical short gray lines indicate where the control points are in the spline that is projected [IMG_1697]

This never works. The projected points are completely random. WTF. Complex lofting just got a million times more tedious.

If you project fit splines it gets converted to control splines.

Yeah I noticed. I was thinking it took the points and tried to fit a new spline. Had to draw straight lines to transfer points. Feels like a silly work around, however it actually works.. [IMG_1698]

I suppose that’s because the projection tool projects the geometry itself. It just doesn’t care which tool you used to create that geometry, and that’s quite logical.

I learned this when converting from Affinity Designer to CAD curves. In AD you control like fit splines but when it’s exported to DXF/DWG and imported it gets converted to control splines.

Ok, so you need to loft? Curious now how your lofting strategy works.

I want to project curves to plane to create rails correctly. Unfortunately rails do not work very well either. For some reason they don’t follow the curvature. I’m trying to loft a shoe using only 4-5 simple splines with only 5 points in each profile. I’m at this point because nothing is predictabl…

Wow. Apparently I cant alter the angle to much. Even though the edge is sharp, loft doesn’t understand. Great, another limitation.

I think I know the issue you have, your trying to do surfacing but Shapr got no surfacing tools.
