Scaling an STL in Fusion 360
Posted: Thu Sep 26, 2024 11:55 pm
I'm going to dump this here so that is easier to find...
Step 1. Obtain your stl, noting what scale it is supposed to be. I am going to use this one because its is free: https://cults3d.com/en/3d-model/game/ca ... -1-35-tank
Step 2. In a new empty part, in the solid (or surface, or mesh, doesn't matter) tab, Insert > Insert Mesh.
Step 3. Make sure you have Unit Type set to 'Milimeter' in the dialogue box, otherwise it will import using centimeters as the unit of measure and your scaling will be out (this is what happens if you use File > upload instead of Insert Mesh)
Step 4. Check the scale by measuring something on the mesh that you can verify against published figures, i.e. the overall width:
Step 5. In the Mesh tab, Modify > Scale Mesh
Step 6. Pick the imported Mesh, pick any point on that mesh (make sure Scale Type is set to 'Uniform'), and enter your desired scale - in this example I have a 1/35 scale mesh, and I want 1/16, so therefore the scale factor is 35/16. F360 will very helpfully accept an equation rather than a figure, so you don't even need to get the calculator out...
Congratulations, you now have a 1/16 scale mesh:
What you do with it after this point is entirely your own problem...
