Curve modeling

Choose POLY for deliberate straight segments and BEZIER for smooth paths. Supply control points in scene units, choose handle behavior explicitly, then set bevel depth, bevel resolution, and path resolution according to the intended silhouette and preview distance.

Keep curves editable until downstream mesh-only work requires curve.to_mesh. After conversion, treat the result as a new mesh topology and run mesh inspection. Verify control-point order, cyclic state, profile thickness, sampling smoothness and endpoint placement. The current interface supports one spline per created curve and a round bevel profile; use a disclosed fallback when custom profiles or multiple splines are required.

什么时候使用（When to Use）

需要路径、线缆、轨道、管线或曲线驱动道具，并希望保留控制点和参数化厚度时使用。必须布尔或雕刻时再转网格。

输入与前置条件（Prerequisites）

• 明确用途、坐标系、单位、控制点顺序、闭合状态和目标粗细。
• 平滑路径选择 BEZIER 并指定 handle；折线路径选择 POLY。
