Use the radio buttons and the list within the Base Feature field at the bottom of the Create Part dialog box to select the base feature of the part you are creating. The choices depend on both the part's modeling space and the part's type; for example, an axisymmetric deformable body can have only a planar shell, planar wire, or point base feature. For detailed information about the different shapes and types of base features that you can create, see “The base feature,” Section 11.3.2.
Your choice of the base feature's type is important because you cannot change the type after you create the part. You can modify the base feature, but you should be aware that any features you subsequently add to the part will be linked to the base feature. Consequently, if you modify the base feature, these dependent (or child) features may move or fail to regenerate.
To choose the base feature:
From the bottom of the Create Part dialog box, choose the desired base feature shape (Solid, Shell, Wire, or Point). The available choices depend on the modeling space and the type of the part you are creating.
If you are creating a three-dimensional deformable or discrete rigid part, you must also choose its Type (Extrusion, Revolution, Sweep, Planar, or Coordinates).
When you have finished choosing options, click Continue to close the Create Part dialog box.
The Sketcher starts, and you sketch the profile of the new part's base feature.
