How these drawings were generated

These drawings were generated from the source 3D CAD geometry. The system analysed the model, selected relevant views, planned section cuts and generated drawing sheets in PDF, SVG and DXF formats.

These are 2D engineering drawings, not 3D files. Dimensions are extracted from the 3D geometry and should be verified against the source model before use in manufacturing.
