Extrusion Draft Angle

In this Task 

A 2D polygonal shape will be drawn, then extruded using an extrusion draft angle.

Before you Start 

Use the sample drawing for this Session.

Set the view to any Isometric view.

The Workplane is displayed and is set to Plane by World.

Extrusion Draft Angle

Ribbon : Draw | Draw 3D | Simple Extrude

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

Palette : 3D Model | 3D Object | Simple Extrude

A draft angle can be applied to an extruded object to create an extrusion taper.Draft angles can be applied to all extruded profiles, such as a cylinder, polygonal prism, etc.

Somewhere in the editor, insert a construction circle to a radius of 50.  This will assist with construction where a central axis is required.

Draw an 8 sided polygon, with a radius of 50.  Make sure the polygon is set to segment mode so that the circle is circumscribed about the circle, shown below. So that the flat edge is at the top or side of the construction circle, drag the polygon to the edge of the circle and input Q to target the quadrant.

Select Simple Extrude from the menu options above, right click and select Properties.  From the Simple Extrude Shape page, input-5 into the draft angle field.  Click OK when finished.

Select the polygon and extrude upwards by 50.

The result is shown below.
