loft not working

Anonymous — Wed, 28 Jul 2021 05:05:09 GMT

I'm new to Fusion and I'm trying to get loft working. I've got two simple shapes but loft doesn't work and gives an error.

Any help would be appreciated. Here's the link:

A360 does not display sketches, did you download anyway?

@davebYYPCU it does not show a download link on my end. AFAIK, users of the free version cannot make their designs available for download using the link.

THis is my first attempt so I've probably made lots of errors.

I've trying to make a loft between the two sketches. It's a bike seat cowl.

You don't have quite enough information here for Loft. I added a sketch, and a rail curve to help guide the surface:

That allows the loft to succeed:

The edges on the side are because you have some non-tangent lines in sketch1:

So, Loft needs to create these non-tangent edges. I would re-do sketch1 with a single spline.

Finally, if this is symmetric, I would sketch/loft only half of it, and then mirror the body.

Blue lines and white dots are not recommended.

Dimensions are recommended.

Due to the hour glass necking, the geometry as it is - prime for self intersecting.

At a side view rail will get a shape, you need to adjust for the purpose....

Cleaner results will come with better preparation.

Might help.....
