Conversion from SLDASM to Sketchup is not supported yet :(

SLDASM is a SOLIDWORKS Assembly File. It refers to a SOLIDWORKS 3D assembly, which consists of several SOLIDWORKS part files (SLDPRT). An assembly file itself may contain some children SLDASM files, as well as some SLDPRT part files.

SLDASM are proprietary files with closed specifications. Nevertheless, some APIs (like CAD Exchanger SDK) provide the facility to read and convert them to other formats.

Software applications like Autodesk Fusion 360, Okino PolyTrans, and AMADA SheetWorks can import and render SLDASM files created with SOLIDWORKS.

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.
