Should I use this
Quality & Safety
Based on automated analysis of tool definitions and protocol compliance.
Context Cost
This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

Tools (4)
🟢inspect_cad(file, upload_ticket, ref, wait_seconds)
Open a CAD file on CADProps servers and report its format, size, volume, area, units and accuracy, with an interactive 3D preview. Supported: 3DM, 3MF, ASM, CATPART, CATPRODUCT, DWF, DWFX, DWG, DXF, GLB, GLTF, IAM, IGES, IGS, IPT, JT, OBJ, PAR, PDF, PRT, PSM, SAB, SAT, SLDASM, SLDPRT, STEP, STL, STP, SVG, X_B, X_T, ZIP. Creo .prt/.asm files and CATIA .CATProduct files show only the thumbnail saved in the file (no 3D, no measurements). Call with no file to get a one-time upload link. Files are deleted about one hour after upload.

}🟡convert_cad(ref, target, step_kind, wait_seconds)
Convert a file opened with inspect_cad to STEP, STL or GLB and return a download link that expires in 30 minutes. STEP is a solid B-Rep when the source was read exactly; otherwise it is a triangulated STEP that CAD software cannot edit as a solid. STL and GLB are always triangulated meshes.

}⚪open_in_workspace(ref)
Return a one-time link (valid 15 minutes) that opens this file in the CADProps web workspace for measuring, sectioning and sharing. After it is opened, the chat preview and links for this file stop working.
