.stl files get scaled down


Having an issue with creating sil files and bringing them into a slicing program for printing. My rhino file is set in inches and I will export the model as an .stl. I import it into my slicer and it will import tiny. I will have multiply by 2540 instead of 100. That is a conversion number from inch to cm. What I don’t understand is that other people will send me .stl files done in inches and they will import into my slicer full scale? :confused:

Yeah… STL files don’t carry units info and your target software is assuming cm - if there is no setting there, then scale the object before exporting. 2540? 2.54, right?



Ah that is right.
