Mesh are too big

Hi, when I import mesh files .stl from other software, usually they are out ou scale, how can I solve that?

They usually are huge when imported

Hi,

You need to use the scale command. I have just shut fusion down for the night or I would give you a screen shot.

I think it is in the Modify menu and allows you to re-scale in each or all three dimensions. Callibrate may also work

but I don't work with meshes often so I haven't tested it.

The normal reason this happens is because when you import these files into fusion, fusion can only see a scale in

"units" and so fusion uses its own default unit which is likely different. The other software might use some subscale

unit to model and so 100 might only be 10mm but fusion calls 100 that many millimetres.

Cheers

Andrew

I saw that scale command and tested, but I think I'm not going to have a precise size

How much out of scale are they? Would they be 2.5 times or even 25 times, by any chance?

If so, check the units used by the software that produced the files and match those units in Fusion

If you use the File/Open menu, Fusion will use centimeters with no option to change the units. If you use Insert/Insert Mesh, it will use the document unit settings and also give you the option of setting the units.

@spoofusion

Insert Mesh is into an already Open file?

Set your default units to millimeters, start a new file, and use the Insert Mesh command to open the mesh.
