Primitive

Use the Primitive tools to create a single PolyNURBS solid or surface, either around a selected object or as the starting point for a new model. This is the tool you should start with if you want to build PolyNURBS geometry without wrapping or paving.

Create a PolyNURBS Solid

Create a PolyNURBS block in space or around a solid part.

  1. On the PolyNURBS ribbon, select the PolyNURBS Solid tool.

  2. Choose from the following options:
    • If there is already geometry, select a solid part to surround with a cage. A PolyNURBS is created around the bounding box of the part.
    • If there is no geometry, you don't need to do anything. A PolyNURBS block is created automatically.
  3. Edit the PolyNURBS as needed. Right-click and mouse through the check mark to exit, or double-right-click.
Tip: If you want to select multiple parts, it is faster to select all of the parts before clicking the Create tool. A PolyNURBS is created around the bounding box of each part.

Create a PolyNURBS Surface

Create a 2D PolyNURBS surface in space or around a surface part.

  1. On the PolyNURBS ribbon, select the PolyNURBS Surface tool.

  2. Choose from the following options:
    • If there is already geometry, select a surface part to surround with a cage. A PolyNURBS is created around the bounding box of the part.
    • If there is no geometry, you don't need to do anything. A PolyNURBS surface is created automatically.
  3. Edit the PolyNURBS as needed. Right-click and mouse through the check mark to exit, or double-right-click.
Tip: If you want to select multiple parts, it is faster to select all of the parts before clicking the Create tool. A PolyNURBS is created around the bounding box of each part.
