Loft Path not woking

dora0206 — Tue, 11 Mar 2025 01:51:12 GMT

After I make the loft, I hit Enter, type Path, select the path, then the loft disappears and nothing happens.

I believe the both ends of the path are connected to the cross section, so I hope to get some advices here.

Hi,

>> then the loft disappears and nothing happens.

It's normal to get such a result because of unproper conditions for LOFT command. The rectangle is too big for the path and the circle. It will be fine if you reduce the rectangle for a proper size.

The rectangle is too large for lofting along the small radii of the spline. Either decrease the size of the rectangle (as shown in the video) or use a less bended spline.

Almost

The short dimension of the rectangle is good and can be narrower or wider as it is parallel to the path

in the attached, I offset from the narrow rectangle until if failed to loft. the red lines are almost at the limit. the limiter is seen from front view.

The soild will self intersect causing the failure if the rectangle is 4056.52 + some amount which I didn't try. at 4156.52 the loft fails.

When I wrote that the rectangle is too large in relation to the radius of curvature of the spline, that indirectly means (in this current example) that it is the rectangle's extension in X direction. In Y direction of course the rectangle can be as large as you want.

so now my question is how to place maybe another spline or two to loft the rest of the solid in parts for a UNION?
