Use this procedure to define a profile from a polyline to create either of the following mass elements:
- Extrusion, in which the shape of the two-dimensional (2D) profile is projected to create a 3D mass element
- Revolution, in which the 2D profile is revolved around its X axis to create a 3D mass element
You can draw more than one polyline within the outermost polyline to create voids in the resulting mass element. Polylines cannot intersect or overlap.
- Draw one or more closed polylines in the shape you want to extrude or revolve.
- Select the polyline, right-click, and click Convert To
Profile Definition. - Enter c (Centroid) for the insertion point of the profile.
The insertion point of the profile is aligned with the centroid of the mass element.
- Press Enter to specify a new profile definition.
- Enter a name for the profile, and click OK.
You can now use the profile as an Extrusion or Revolution mass element.
