3D scan processing - "combine" Mesh sections?

[Anonymous]

Hi guys,

is it possible to somehow combine Mesh selection (each in different planes) to create Solid body (or Surface) in F360?

Please see attached picture. I was thinking about Lofting the "circular" ones and define Rails, but didn't work this way (either if the section is closed, or is just the line over).

I think I saw something similar in Rhino (which is working in different way as F360, but still).

Thanks.

No *.f3d file is Attached?

Oops, OK, now I see it.

In general, what you are trying to do can be done for this sort of object.

However, you'll have to create a "real" sketch based on these mesh sections and thee are specific tools for that in the sketch tool section.

You either "trace" these section sketches manually, or you use the "Fit curves to mesh sections" tools:

 

However, the number of mesh sections and where these mesh sections should be located is not sufficient to accurately represent that geometry. I would not create this in a single loft!

Please, see attached f3d file.

Sections are traced by Fit Curves of course.

I made around 15 sections of this object and Lofted it. It works, but I can imagine it could be done with less effort and larger precision.

My idea is make rough Loft from 3-5 sections of shape, and after that 2 sections in other planes to make "boundaries" for rought Lofted shape.

I've added it yesterday, after notification from TheCADWhisperer. Try look more carefully.

I guess I should have read your initial post again 😉 (did that yesterday)

Depending on what you want to do with the model you can of course use Mesh Sections.

However, another solution would be to remesh this triangulated mesh into a quad-mesh (I used InstantMeshes) and then import that quad mesh and create a T-Spline and then solid.

Here is a tutorial that describes the overall process:

Yes, thank you.

I'm familiar with process scan data through quad mesh, but still I'm curious if is some way how to do it way, which I mentioned above.... 🙂

[TrippyLighting · Accepted solution]

Yes, of course, that is possible. I thought I'd explained the general workflow already?

In this screencast, I am only showing the result. Aligning the scan better to eh main axis/origin would still increase accuracy but it is pretty close already. Pay close attention to the locations of the mesh sections, to the order of the lofts, and to the loft settings.

I first created the lofts for those areas with low and even curvature. Then I created intermediate lofts between those for areas with high curvature and in the loft, settings used the Tangent setting. That obviously requires the rail splines to be tangent as well.

I left the end of the handle for you to figure out 😉

This is about 20 minutes of work.

If better surface quality is desired I'd suggest hand-tracing the mesh section with CV splines.

Thank you very much and for your's time.
