Key points and edges in the x-y plane. The arc center point has been cut. Save the OSM model file. 2.4 Sweep to Create a Solid We can sweep the points and edges in the x-y plane along the z direction, performing an extrusion to create another set of points and edges while also creating the connecting edges and surfaces. Swept points create edges along the sweep direction.
Swept edges create surface patches along the sweep direction.
Sweep to create a solid object. Select the Sweep menu button, and then select Cartesian Sweep from the sub-menu that appears. Select Accept in the dialog box. Normals to the patch are indicated by vectors emanating from the corners of the blue polygon. If some of the patches have normals that are directed into the solid, we must reverse the normals.
