Conversion from SketchUp to SOLIDWORKS Composer 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.

SOLIDWORKS Composer is a SOLIDWORKS tool to create high-quality graphical assets from the 3D CAD designs for technical and marketing documentation.

It is used to make manufacturing assembly instructions, product manuals, installation instructions, service manuals, training guides, marketing brochures, and sales bidding kits. The available graphics vary from 2D content to interactive animations.

According to the package, SOLIDWORKS Composer allows users to interact with a model, use custom APIs to customize the player, launch CAD files batch conversion, support PMI data, and identify design errors.
