Extending or Trimming Adjacent Surfaces

  1. Click Extend in the Analysis group of the Prepare tab.
    The edges of surface parts or sketch curves that can be extended or trimmed are highlighted.
    Chains of tangent faces are automatically grouped to offset them together.
  2. Change the following options:

    • Maximum distance: The maximum distance between surfaces. The tool will search for adjacent faces again if you change this value.

    • Trim surfaces: Controls whether or not surfaces may be trimmed in addition to extended.

    • Partial intersections: Controls whether or not faces that partially intersect are detected.

    • Same body: Allows a surface to be trimmed or extended by a face or edge on the same body.

    • Merge after extend or trim: Merges bodies, if possible, when you trim or extend an edge on one surface body up to a face or edge on another body.

  3. If you want to extend or trim only some of the surfaces or sketch curves, click the highlighted spots.
    Hold Ctrl to select multiple edges.
    The surfaces or sketch curves are extended or trimmed when you click them.
  4. Click Complete if you want to extend or trim all highlighted surfaces.
    Press Esc to cancel the operation.
