Hi.
I was watching this guy using loft and I wanted to do kind of similar thing but it doesn't work and I need some help.
I don't know why it's saying its self-intersecting or bad geometry. It shows yellow ghost and says 'rails can not be tangent to profiles!' which I don't really understand what it means.
Could somebody enlighten me please?
f3d file is attached.
thank you.
I suggest that you re-design this using fewer spline control points and also turn on the timeline.
If you just started out with Fusion 360 you should familiarize yourself with some basics, before getting into lofting!
I don't understand from the file quite what you tried to do- showing history would help us to understand this. Using as few control points as possible is just good practice and will yield better results.
Your issue with the loft not being valid is that you are trying to do something inappropriate with the tool. You have two curved splines that are (probably) tangent, and they are even in separate sketches. I think to achieve what you want you would have to use a single spline in one sketch for this part of the loft.

Thanks for the reply.I'll make sure I learn the basic.
Based on what you said, are you saying using fewer control points and turning on timeline will solve the issue that I'm having?
No, but it results in much better geometry. Too many spline control points result in uneven curvature and this, in turn, can often lead to modeling problems later.
The main problem with this loft is, that it lofts into a singularity (or at least it looks like it). That also usually results in curvature problems and is the most prevalent reason why geometry later cannot be shelled or thickened.
