How to convert SKP to STP
- Add your .SKP file - drop it in the box above or click to browse.
- Convert it to .STP in a few seconds.
- Download your new .STP file.
What to expect
- STP and STEP are the same ISO 10303 format under two extensions; the conversion result is identical.
- SketchUp's faceted geometry may come across as surfaces rather than solid bodies, and materials/textures are not preserved.
- The STP is plain-text geometry with no executable code; large assemblies can be slow to open or heavy in size.
Frequently asked questions
Does .stp differ from .step for this conversion?
No. STP and STEP are two spellings of the same ISO 10303 format, so the output is the same neutral CAD model either way - the extension is just a naming convention different programs prefer.
What is kept when converting SKP to STP?
The geometry is exported into the STP CAD format, but because SketchUp models are faceted surface meshes, they may appear as surfaces rather than clean solids, and materials and textures are not carried over.
Why convert an SKP to STP?
STP is a neutral CAD interchange format, so converting moves a SketchUp model into mechanical CAD programs that cannot read the proprietary SKP format.
Can I open or 3D print the STP?
It opens in free tools such as FreeCAD, CAD Assistant, and the online Autodesk Viewer. For 3D printing you must convert the STP to STL first, since STP itself is not a printable mesh format.
