Extrude Solid

Modify | Draw | Solid from Curves | Extrude Solid

This extrusion tool sweeps a 2D profile in a plane perpendicular to the Workplane to create a 3D object.

A bi-directional extrusion can be created which creates an equidistant above and below Workplane extrusion.

Closed profiles only can be extruded.

When closed objects within the profile are selected as part of the profile, the volume of the extruded inner objects will be subtracted from the primary solid.

When two separate regions are selected together to create an extrusion, they will form a single unit.

Additionally, a common curve can be used to create two separate extrusions, providing the region forms a closed boundary.

In this task, the outer region of the profile shown as region 1 will be extruded to a height of 12. The two regions shown as region 2 will be selected together to form a single unit, then extruded to a height of 48.

From the illustration below left, the common curve shared by both regions is shown.

Set the view to Isometric by right clicking in the editor and selecting View > Isometric.

Select the Extrude Solid tool, activating the Distance option. TAB to the edit field and input a Distance of 12. Hold down the SHIFT key and select the curves shown below, including the inner circles.

Still in the Extrude Solid tool, TAB to the edit field and input 48. Turn the view to Top, then hold down the SHIFT key and select first one region, then the other.

Both profiles have been extruded to create a single unit, shown below.
