Conversion from Sketchup to SAT is not supported yet :(

An SKP file is a three-dimensional model created by SketchUp, a 3D design program. It contains a model with wireframes, shades, edge effects, and textures.

The SKP file enables conceptual designs to be created, viewed, and shared quickly and easily. When you create a new document and save it in SketchUp the SKP file is created to store the document and its contents. SKP files can also be used to store SketchUp components. Components may be made by you or another user and can be imported into an SKP document to be inserted into your model.

A SAT file is a 3D model used in ACIS CAD modeling software by Spatial Corporation.

The format's name stands for Standard ACIS Text, since the content of a SAT file is stored as ASCII text. In ACIS, the same data can also be saved in binary form with SAB extension.

SAT files are used to communicate 3D data across different 3D CAD tools, such as Spatial 3D ACIS Modeler, Autodesk AutoCAD 2017, IMSI TurboCAD Pro 2016, Dassault Systèmes SOLIDWORKS, etc.
