SketchUp groups and STL solid naming convention:

Geometry Preparation

• If submitting geometry using STL file format:

• Use meter units;• Ensure that parts are correctly splitted and that the

solid are named correctly (ie as per the previous slide);

• If submitting geometry using the SketchUp file format:

• Ensure that group and components are named correctly.
