What is the final stage when using the Poly Shape tool after creating all control points?

The final stage when using the Poly Shape tool, after creating all the control points, is to set the mesh height. This step is crucial as it defines the vertical dimension of the mesh created from the control points you have placed. The mesh height determines how tall or elevated the shape will be in the 3D environment, influencing not only its appearance but also how it will interact with other elements in the scene.

Setting the mesh height is integral because, without it, the shape may exist only as a two-dimensional outline without a defined volume. By adjusting the height, you complete the 3D representation of the object, preparing it for subsequent processes like texturing and UV mapping, which build upon the finalized geometric structure. Therefore, focusing on this last step enables a smooth transition to further enhancements in the modeling workflow.
