Partition Parts

Divide a solid part into design and non-design regions by selecting a hole, pocket, or face to offset.

  1. On the Geometry tab, in the Modify group, click the Partition tool.

    Holes and pockets are automatically selected and shown in red.
  2. Select faces to partition.
    Selected faces are shown in red.
  3. Click a selected (red) feature to execute the partition, or click the Partition All button on the guide bar.
  4. Use the microdialog to edit the default offset value. You can edit the offsets for multiple partitions while in editing mode.
    • Use the +/- button to change the direction of the offset.
    • Change the Thickness and press Enter. If the thickness you entered is invalid, the text box is highlighted in red.
  5. Right-click to exit the tool.
  • If you apply a partition to a design space, it automatically creates a non-design space.
  • For solids, if you enter a thickness of zero, you will get a surface in a new part. For surfaces, if you enter a thickness of zero, those surfaces will be placed into a new part.
  • You can edit the Default Offset value in the Preferences.
  • Only solids can be partitioned, not surfaces.
