What it does
Use the Assembly tab to join parts and sub-assemblies with mates, drag parts so they move with their joints, explode the view, and pass the result on to Drawing / BOM. Assemblies are saved as .metasm.

Typical workflow
- Insert Part the first part. It is fixed in place as the base.
- Insert the next part, then add a Mate or use Auto Mate.
- Drag parts to check how they move. See Drag and move parts.
- Save as
.metasm, then create a Drawing or Auto BOM.
