Good luck!

You might find Autodesk Meshmixer is a better application to work with triangulated meshes.

 

Also, it usually helps if you can share the model in some form.

If this is your first day with Fusion 360 you should by all means go through the tutorials in the Learn & Support section of this Forum. Afterwards you'l have questions but you will be much better equipped to ask questions.

 

Fusion 360 is a CAD program and .stl files are NOT CAD geometry. As such you'll have an uphill battle on your hand if you continue.

I am not a student, I am MD, but this is my first time with Fusion360.

I need to learn how to modeling medical implants from CT scan. A 2D model is showed in attached pic.

So 

1. I convert DICOM files /images from CT or MRI/  to .stl

2. Convert Mesh to BRep

3 Slice two cylindrical parts from bone with radius of bone saw.

4. Rearrange them in correct way.

5. Merge some facets to a single profile.

6.!! now I need to loft these surfaces but "Warning: Could not approximate the notional curve for a boundary geometry"

7 when I get this body I plan to add some support material and screw holes.Screen Shot 2019-08-07 at 9.32.34 AM.png

I learn how to work with program in the same time.

If you can give me advice how to do it in fusion or which program to use it will be a great help

Please zip and attach the .stl file. I can show you a method how to do this!

However, still, go through the tutorials as the will provide a basis for continuing work in Fusion 360.

Thank you very much. These files are .stl and .f3d after cutting cylindrical shapes and one .obj file before cutting procedure.

Best regards!

One approach would be to re-mesh the scan from a triangulated mesh into a quad mesh. That you can use in Fusion 360 and convert it into a T-Spline and then into a solid body, or BRep

 

See if this tutorial makes sense to you:
