To Create Offset Surfaces with a Draft
1. Select a surface, and click Model > Offset. The Offset tab opens.
2. Select Offset with Draft as the type of offset.
3. Select an existing sketch, or click Define on the References tab and use Sketcher to define a sketch. You can also right-click the graphics window and choose Define Internal Sketch from the shortcut menu.
4. Enter the required offset value in the offset value box. An offset surface is shown in preview geometry parallel to the referenced surface.
5. Click the Options tab and specify the offset method:
◦ Normal to Surface (default)—Offsets the surface normal to the reference surface.
◦ Translate—Offsets the surface and retains the shape and size of the reference surface.
6. On the Options tab, specify the side surface type:
◦ Surface—Offsets the side surface normal to the surface.
◦ Sketch—Offsets the side surface normal to the sketch.
7. Specify the side surface profile type:
◦ Straight—Creates straight side surfaces.
◦ Tangent—Creates fillets for the side surfaces and neighboring surfaces.
8. Enter a value for the draft angle in the box, or drag the handle in the graphics window.
9. Adjust the dimensions and options, and click to finish the offset.
 
• You can also open the Offset tab by selecting multiple surfaces and clicking Model > Offset. The surface collection can include single surfaces, loop surfaces, boundary surfaces, intent surfaces, or any combination of these surfaces.
• If you are using a surface set as a reference and you want to modify it, click Details on the References tab and use the Surface Sets dialog box.
• If you want to modify an internal sketch click Edit on the References tab and use Sketcher to edit the sketch. You can also right-click the graphics window and choose Edit Internal Sketch from the shortcut menu.
