How do I scale an STL file?
Step 2: Edit STL file
- To combine two meshes load both models.
- Click on Show Layers.
- To transform, rotate or scale an object, first select it in the Layer menu and then click on Manipulator Tools.
- You can now press T to select the Transform option, R to rotate the model and S to start scaling.
Do STL files have scale?
STL has several backronyms such as “Standard Triangle Language” and “Standard Tessellation Language”. This file format is supported by many other software packages; it is widely used for rapid prototyping, 3D printing and computer-aided manufacturing. STL files contain no scale information, and the units are arbitrary.
How do you scale a STL in NX?
- cowski1. 3 years ago. Menu -> edit -> transform, select STL body, choose “scale”, specify a point to scale the body about, enter the desired scale factor, and in the final dialog, select “move” to transform the exisitng body or “copy” to create a new (scaled) body.

What units are STL files in?
STL files are unitless, so they don’t contain the actual units. Most people use mm, as that is what all of the 3D printing slicers seem to expect. When you import the file, you can set the units to import in, and then the scaling should be correct.
What is a convergent body in NX?
What is Convergent Modeling? Convergent modeling works with facets, surfaces, and solids without any conversion. This means you can import your STL or scanned data to NX as a convergent body and use your traditional modeling commands. You can then create geometry on or around the facet.
What’s the correct scaling for a STL export?
Henceforth, there is no ‘correct’ or ‘incorrect’ scaling when exporting. User has to define itself which unit he wants his STL to be in, and set scaling accordingly. Previously, scene’s scaling (aka scene units) was not taken into account at all, so a 1BU object was always exported as 1BU, disregarding actual scene unit.
Is the size of a STL file arbitrary?
Scale is not arbitrary. It is. Turns out, Stl file format doesn’t include scale (multiplier, percentage) nor unit in the file so if the target application has scale value exposed, one could choose whatever scale to end up with correct dimensions. Dimensions aren’t arbitrary when interfacing with the real world.
Which is the default unit for STL export in Blender?
Consequently, each application exports STL files in its own, default unit. For Blender, it happens to be meters. So if you want your STL data to be in millimeters, and your scene’s uses that unit too, you have to either: Disable ‘Scene Unit`.
How to set the export scale for Blender?
1 Blender unit equals 1m, but STL seems to assume 1 unit as 1cm. If you want 1 unit to be 1mm, set Scale on STL export to 0.1 and. Scene Scale to 0.001 to make it match the output scale in viewport. Note that the STL will be 10x smaller if you re-import it into Blender!
