The prompt
Create a simple, functional 3D master sketch CAD model for an FTC robot, compatible with Onshape. Include: - Front, Top, and Right reference planes intersecting at the origin. - A centered 18 × 18-inch configurable chassis outline. - Four wheel and axle locations, plus motor mounting zones. - Reference zones for the battery, control hub, and future mechanisms. - X, Y, and Z axes, centerlines, construction geometry, and editable dimensions. - Simple placeholder geometry, not detailed robot components. - Organized sketches and reference geometry for future CAD modeling. Export a genuine STEP file for 3D geometry, an editable DXF for the 2D master sketch, and a native CAD file or source script if possible. Verify dimensions and file validity. Keep everything minimal, editable, and suitable for adapting to current FTC rules and actual robot components.
