Isomtric /3D Extrusion & Rotation Engine

The one am using currently within adobe illustrator Is fine my only issues is that the current one rounds the decimal numbers ( which it shouldn’t) and makes the isometric projection wrong. also its limited to local coordinates making it hard to customize the isometric projection ( True Isometric, off Axis isometric etc etc ),
Am not much of a programmer but I tried to vibe code a standalone vector 3d processor with many features I needed in my workflow:
- For example if my extruded shape had separate vector paths I can offset the position of each one making it helpful in technical drawings where parts are offset from each other
- shading I can Limit How much shading is applied on the final output so That I don't end up with a messy vector shape with many vertexes

No source file, test, or entry point is identified. First clarify the projection, decimal-precision, coordinate-system, per-path offset, and shading requirements, then define a focused first milestone and its acceptance criteria; completion is not yet concrete from the issue alone.
