Hi martijnFBAFA,

STL files are unitless. If the STL you're bringing in was designed using CM and Fusion is set to MM, the STL will be 100 times the size it should be. My guess is that the STL was designed in units that are different from what you're using in Fusion.

Insert rather than Open - this will give you the option to set appropriate Units.

I found the problem this evening .. Opening an stl file thru the file ->
open file part of fusion makes the stl file 10 times bigger then the
orginal ... How that is possible i dont know but the answer lays in using
the insert tab-> import mesh and open stl then.
Next prob then you cant convert the mesh too brep ... Solution is to
disable the timeline and then use the mesh to brep tab when you rightclick
on the mesh piece
