Pitts Biplane — STEP, CATIA and STL Aircraft Sources

Pitts Biplane digital aircraft assembly. Biplane aircraft CAD design with two wing levels, interplane struts, rounded fuselage, tail surfaces, propeller, main gear fairings and a tail wheel.

PACKAGE CONTENTS
The ZIP contains the original native STEP assembly, a derived STL for display and an English source-file guide. All added filenames are in English. Original CAD bytes are unchanged. The derived STL is supplied separately as the web viewer.

GEOMETRY VERIFICATION
The native STEP was imported into local FreeCAD and its 99 nonempty shapes tessellated into 236638 triangles with 0.15 source-unit deflection. The resulting assembly was imported into Blender and visually inspected. The STL does not preserve native CAD hierarchy or editing semantics. Source units and real physical dimensions have not been independently confirmed.

ADDITIONAL NATIVE SOURCE FORMATS
The earlier 2 downloadable files remain unchanged. This added English-named ZIP preserves 6 original native files with a complete filename mapping guide. These are editable source formats or additional source versions; matching coordinates, dimensions and interchangeable components are unverified.

ON-DEMAND INSPECTION
Select the compatible existing model files and any separately supplied source-derived STL inspection views when needed. Lightweight views normalize coordinates and may simplify dense geometry; original native bytes remain in the ZIP. Native documents not supported by the web viewer require compatible local software. Assemblies and materials may need reference relinking to the English filenames, and their resolution is unverified.

PREPARATION AND PRESENTATION
The cover is our own locally generated ComfyUI photorealistic miniature biplane finishing illustration, with both native wing levels, new paint and a workshop scene. Orange MESHOPIA lettering appears at the lower left. Supplier pictures remain private references. Additional formats do not establish a newly manufactured or tested build. Inspect original units, dimensions, topology, thin features, supports, component quantities and fit before fabrication. Flight, RC operation, moving parts and compatibility are not independently tested. No physical item, hardware, paint or electronics is included.

Original native source bytes preserved under English filenames with a mapping guide; earlier downloads and representative MESHOPIA imagery retained. Additional compatible inspection views are source-derived and do not establish physical scale or tested operation.
