Budweiser compatibility benchmark (v1.3) by CAD Studio for diagnostic testing of DWG-compatible applications. We ran this to verify rendering of complex polylines, splines, and 3DSOLIDs across various engine versions. Drawing contains 21 test blocks evaluating text styles, colors, layer visibility (up to 99 layers), and OLE object display. Precisely mapped coords at X=-1200015.0000123 / Y=-800025.0000123 ceck for floating point precision errors typ. found in lower-end viewers. Layout Bud1 covers paper space clipping and Bud2 features a stress test with 28 simultaneous vports. Technical specs incl. polyline width tests, intersection precision, and font readability for special characters like the Euro symbol. Dims set in Metric (mm) at 0.05 scale.
