How curve edge and how fit to surface

[jonniepickering]

Hi folks,

A couple of questions please.

I have created this sculpture of a spoiler extension for a car. I have created one half so it can be mirrored.

I want to please create curved edges please, the back edge should be fully curved and the front edges that attach to the existing wing should just curve down to the surface (90 deg)

Two pictures below and full export attached.

Thanks

Also one other question

How do I cut away the unwanted material from the inside of the model so it fits the rear of the existing wing.

Many thanks

Cool! Here's the 2nd part.

Aha, I see, so once you have completed the t-spline sculpture, you then have to convert it to a BREP and then it's a simple split face exercise.

One question. Is it possible to split the face against the original scan (.stl) face, or will I always have to create a BREP of the scan face first to split against? Just thinking of future projects and the process I will always have to follow.

Will it always be

1) Recreate face as BREP

2) Create new t-spline sculpture

3) Convert sculpture to BREP

4) Split face

Many thanks for this. This is far more than I was expecting!

Legend. Many apologies for how things started..

A T-Spline is really just an intermediary form between a quad mesh and a Brep/NURBS surface.

That is the reason you'll have to convert it. When the T-spline encloses a volume watertight, it converts into a BRep containing NURBS surfaces (in this case).

If the T-spline is open it will convert into an open (NURBS)surface body.

Then I use the split body command utilizing the surface created from the scanned data.

You can't directly use the scan data, as that is a triangulated mesh. This has to be reversed engineered into a surface before you can do much with it in Fusion 360.

OK, that's awesome, thanks!

I guess I'll mark this one as resolved.

Thanks again so much for the help!

Told ya. @TrippyLighting  is a badass. Now if we could just get him to wear deodorant.

One question Peter, how do you get the colour of the final model to change to that greenish finish?

Thanks

Sorry for the very late reply. I stopped getting any Forum notifications 😕

I use color cycling:
