Extrude using a section with self-intersecting curves

This example shows how to extrude a section with self-intersecting curves as a single feature.

Procedure

  1. Make sure the Customer Default setting will allow self-intersecting sections.
    • Choose File tab → Utilities → Customer Defaults → Modeling → General.
    • On the Miscellaneous page, select the Allow Self-intersecting Section in Extrude Feature check box.
  2. Choose Home tab → Base group → Extrude.
  3. Select the section curves.
  4. Set and select the desired parameters. For this example:
    • Offset = Symmetric
    • Start/End = 2.0 and 2.0
    • Limits (Start/End) = 0.0 to 5.0
    • Inferred = Boolean (Unite)
  5. Choose another command or click Apply to complete the extrude.

How do I

  • Extrude a solid body
  • Create an extrude feature with an offset
  • Subtract an extrude feature
  • Extrude between two bodies
  • Extrude with an asymmetric angle
