How to convert or export SketchUp graphics to STEP format. Available skp to stp converters.
It is certainly possible to export 3D models saved in SketchUp graphics format (.skp) to ISO-10303 STEP product data format (.stp). Not every SketchUp file contains proper 3D models though, which means that skp to stp conversion will only be possible with the ones that have the whole models.
