Detta makro konverterar valda nät till delar. Det har en bred tolerans, så använd det bara med objekt som inte har några kurvor, annars kommer du att få konstiga resultat. |

Description
This macro converts selected meshes to parts. It has a broad tolerance, so use it only with objects that have no curves otherwise you'll get weird results
