Create body on top of mesh, which has same form as mesh.

Hi all,

I've been struggeling with this for a while, I've seen this done in some youtube webminars but I just don't get it right.

I work in medical enviroment as an instrumentmaker/mouldroomtechnician, we make special parts for people who get radiation treatment. Some people get radiation treatment which is on, or right below, the surface of their skin.

Now this gives probles with the dose distribution. Therefore we make a sort of extra flap of skin, mostly 5mm or sometimes 10mm thick from casting sillicone which has to fit exacly with no airgaps. Now to make the cast for these Fusion 360 might come in very handy. I've got a 3D-scan from a face imported into Fusion 360 as stl-file. Now as show in this tutorial: https://youtu.be/h2wYWVY5nvY?t=12m21s I want to create that extra flap material on the nose area of the face. The plane just does not get the right contour of the nose area and therefore does not create a perfect fitting shell. I hope it is a bit understandeble to what I want to adchieve.

I appreciate any hep, thanks in advance.

Greetings, Mark.

How are you going to make the mold ? 3D printing ?

For a 1-off this can be done in Fusion 360 albeit rather slow and rather imprecise. Fusion 360 simply lacks the tools to do this efficiently and with good control.

If this needs to be done regularly I personally would NOT do this in Fusion 360.

It can be done but a lot more efficient and with much better control over the end result in Bender (for example).

I've help a designer by modeling Jewelery that needed to fit the exact contour o a nose and the control you have in Blender is far superior of what you have in Fusion 360.

Let me first show you a link to one of my own tutorials, which might show you one of several possible workflows:

If you have a good clean scan of a face then Blender is not needed and using InstantMeshes to re-mesh the .stl is all you need. You can then directly import that quad mesh into fusion 360 and work with the results there.

However, below is a tutorial that shows how to create geometry directly on op of the scan in Blender. the resulting quad mesh can then still be exported from Blender and converted into a T-Spline in Fusion 360.

While all that might be a bit overwhelming, with a little practice these mixed workflows are much faster and more accurate than working with the tools in Fusion 360 only.

Thank you for all this info, I'm will absolutely look in to it!

Strange, but my downloaded and installed version of Blender looks very different from your example.

I did the tutorial with Blender 2.79b. You have probably dowloaded/installed the news 2.8 beta.

The 2.8 beta is already very stable, however, and for your purposes either one would work perfectly fine.

Yep, saw that. Doesn't work either. My surface is just to sharp and edgy. This only works on shallow sufaces.

Could somebody give this a try??
