Loft tangency issues

markzonf360 — Sat, 08 Feb 2025 10:27:56 GMT

Hi, it seems this is an old issue, but I am hopeful someone has a workaround for what is a most basic issue. Can anyone assist with getting tangency through all of these control points? I have been experimenting for hours upon hours, but to no avail.

Hi,

The lower body are heavily fragmented.
The cause cannot be determined as sketches are missing.
Are these sketches available in a different version or are there dimensions that can be used to restore the profiles?

There are no sketches missing. The 'lower body' (is that the surfaced part?) is a set of surfaces extracted from a provided model. There should only be one sketch for the circle. Thanks.

That is exactly the cause!

F360 cannot handle imported surfaces? It was a step file. It's pretty basic?

But if you think this is the problem, I will replicate the surfaces with two sketches and see if the same problem occurs.

Thanks.

That works very well.
However, the imported body was not created “cleanly” and resembles a patchwork

Hi, I updated the model with a new surface using only sketches. The rails are better but the result still has some surface irregularities? Thanks.

Hi,

In this case, it is better to create the fillets in the sketches.
