Compound Profile Extrusion

In this Task 

A hexagonal profile will be drawn, then extruded to a height of 50, using the previously projected circle to create a compound profile.

Before you Start 

Set the view to Isometric South East.

The hexagonal shape is drawn on the Casing layer.

Take Note 

The Workplane is still on the top face of the main extrusion.

Some images below are modified for illustrative clarity.

Compound Profile Extrusion

Ribbon : Draw } Draw 3D | Simple Extrude | Use compound profile (at the base of the editor or right click and select from context menu)

Default Menu : Draw | 3D Object | 3D Profile Based | Simple Extrude |

Palette : 3D Model | Simple Extrude | Use compound profile (at the base of the editor or right click and select from context menu)

A compound profile is created from a boundary profile with interior regions which are automatically subtracted from the volume of the resulting extrusion.The interior regions are selected by holding down the SHIFT key to include them into the selection of the boundary profile before creating the extrusion.

 

Using the center point of the projected circle, insert a 6 sided hexagonal shape using a 2D Polygonas follows :

Select 2D Polygon Ribbon : Draw | Draw 2D | Line | Polygon Default : Draw | Polygon, then active segment mode, shown above left.  Use the center of the 2D profile, inputting C to correctly target the center, shown below.

Using the center of the circle as the center of the Polygon

Turn the view to World Plan and use the outer vertex of the extrusion to define the radius of the polygon, shown below.

Using the outer vertex of the extrusion to define the radius of the polygon

Turn the view to any isometric view and select the Simple Extrude tool.  Select the Use Compound Profile option at the bottom left of the workspace then select the newly drawn polygon.

Hold down the SHIFT key and select the previously drawn circle seated at the top of the extrusion, shown below.

Selecting the Polygon and the projected circle to extrude

TAB to the Height field and input a value of 50.  The volume of the interior circle should automatically subtract from the volume of the extruded polygon, shown below.
