Hello, I searched all over the forums and can’t find whether the STL file unit for the models. Is it cm? mm? inches? Thank you. ---

STL files are unitless, so they don’t contain the actual units. You need units , export as OBJ or ply The units as always are in mm . ---

I did STL. Shapr3d can’t get OBJ or PLY. But again, the units are an issue to what Revoscan exports to. ---

You can’t export STL and having any units , this information is not saved inside STL , no matter what software you use , this format don’t support units . The exported units from Revo Scan are correct and in mm . I work with it on a daily basis. Only OBJ or ply support units data in the files by export . ---

Okay, so it’s mm then. That’s was all I needed. ---

Yes **mm** , I answered you in my first reply already . ---

Right but the first part calling it unitless made it confusing. ---

Because it is unitless by definition and no STL files cares this kind of information . ---

As PUTV says, it has a figure but the units are not specified. It’s up to the program you are importing it in to to decide what units to use. Import a Revoscan STL in to a mm workspace in Fusion 360 and it will be of the correct scale. Import a Revoscan STL in to a m workspace in Fusion 360 and it will be 1000 times too big.
