Hi @Niko
To use a relative path in the File Solid block in Simscape Multibody (e.g., just "CADFILE.STEP" instead of a full absolute path), make sure of the following:.
1. Create or open your project: Make sure you are working inside a MATLAB Project (use the Project tool to manage your files and folder). If you haven’t already, go to Home > New > Project > From Folder and select your project folder.
2. Put the STEP file inside the project folder: Ideally, place your CAD files inside a subfolder in the project (e.g., CAD/CADFILE.STEP).
3. Set the File Solid block path as relative: In the File Solid block, instead of using the full path, just enter the relative path from the project root, for example: CAD/CADFILE.STEP
4. Enable automatic project path management: When you run the project, MATLAB automatically adds the project root and subfolders to the path. That way, blocks that use relative paths can find the files as long as they’re inside the project structure.
Hope this helps!
