Print-ready means measurable
No more one-millimeter specks in your slicer.
Many 3D tools export unit-less meshes. Your slicer reads those units as millimeters, turning a useful model into a tiny dot. Forge STL scales the longest edge to your chosen size, rotates it Z-up, centers it, and seats it at Z=0.
