Tangency control of rails in loft operation

[Anonymous]

Hello,

The Loft tool is one of key modeling operations in F360 for my work but there are some features that are missing.

For now I will talk about the most important one that you should add as soon as possible... The possibility to control the curvature continuity of the rails and not just the profiles.

Most of the times I perform lofts inside a surface patch layout in which all sides are edges (not curves) and all sides should be tangent.

Currently I'm faced with many cases in which I have the rails sides breaking the curvature continuity even if I add many profiles whose curves are tangent to projected curves on the targeted surfaces. The result is not aceptable because even small breaks will be noticed if the part is prototyped or a mould is made to manufacture it.

Best regards,

Carlos

Fusion's surfacing tools are scheduled to have an overhoul during the next year.

This should be visible on the road map that is lso scheduled to be released in the new year.

Enhancements to the loft tool are a must, as the design of some curved surfaces using the Patch workspace in its current state is rather tricky.

In my case it proved really hard to create smooth transitions between all car surfaces (even after a meticulous application of all available curvature continuity conditions) while at the same time assuring that these surfaces weren't bulging or hollowing unintentionally. If you carefully inspect the details of the renderings, it is clear that some surfaces or transitions are not perfect - however this is the best result achieved after long-drawn experimentation!

Even the use of (the current) in-between rails in the loft command does not guarantee a perfect solution in all cases either, as it may just "divide" the whole surface into two sub-surfaces that are bulging/hollowing in turn, with the overall outcome being worse.

Alternatively, perhaps the problem could somehow be solved if the algorithms behind the patch and loft tools provided some parameters to control the shape of the surfaces generated, or a set of surface control points, or sth like that

In the fusion with mates is a big problem, I messed up one project. Just the fillets are built, not tangent to the surface. It is a problem.

No rail tangency is a HUGE issue. This is a very basic functionality in many CAD systems. I was looking at Rhino this morning..............

This request for the loft enhancement is so important for Fusion 360, and I just can't believe that it only has 5 Kudos...

What can we do to gather more people and involve them in this?

This is in our backlog for loft/Surfacing improvements.  Release date TBD.

Hi all

Im having this same issue in loft command during my work with Fusion

Loft- It would be useful for users if the command has the possibility to choose the condition of the rails ( Tangent, Free and Smooth), in my opinion you should apply the same module that exists in Inventor.

Thank you

Our team is wrapping up work on this functionality and it should be released in the next release! Thank you for your idea.
