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

ソースファイル、テスト、エントリーポイントのいずれも特定されていません。まず、投影、十進精度、座標系、パスごとのオフセット、シェーディングの要件を明確にし、その後、範囲を絞った最初のマイルストーンとその受け入れ基準を定義してください。issue だけでは、完了の条件はまだ具体的ではありません。
