Stitch Surfaces and Suppress Edges

Use the Stitch tool to stitch and unstitch adjacent or overlapping surfaces, and suppress or unsuppress edges.

Stitch Surfaces

Use the Stitch Surfaces tool to stitch or unstitch adjacent and intersecting surfaces.

  1. From the Geometry ribbon, Edit tools, click the Stitch Surfaces tool.


    Figure 1.
  2. Optional: On the guide bar, click to define stitch options.
  3. Stitch or unstitch surfaces.
    • Left-click on the surfaces to stitch, then click Stitch on the guide bar.
    • Left-click on a surface edge to advance its topology state from free to shared. Conversely, hold Shift while left-clicking to regress its topology state from shared to free.


Tip:
  • Repair geometry by replacing edges and points.
    • Click-and-drag an edge to another edge, or click-and-drag a point to another point.
    • Select the point(s) to move, then click one of the selected points that you wish to retain and combine with the other selected points.
  • Use window selection to select multiple surfaces, and simultaneously stitch adjacent surfaces and intersecting surfaces. Adjust individual edges if needed.
  • Use the legend in the upper-left corner of the modeling window to assist you in finding edges. Edges are color coded by type. Show and hide an edge type by toggling its corresponding checkbox on and off, or quickly isolate an edge type by clicking Only.

Suppress Edges

Use the Suppress Edges tool to suppress or unsuppress edges individually or by break angle.

  1. From the Geometry ribbon, Edit tools, click the Suppress Edges tool.


    Figure 2.
  2. Suppress or unsuppress edges.
    • Select the surface(s) to suppress, then click on the microdialog to suppress all selected surface edges.
    • Left-click on a surface edge to advance its topology state from shared to suppressed. Conversely, hold Shift while left-clicking to regress its topology state from suppressed to shared.


Tip:
  • Suppress none of the selected surfaces by clicking in the microdialog.
  • Adjust the feature angle used to suppress selected surfaces in the microdialog.
  • Use window selection to simultaneously select multiple surfaces.
  • Use the legend in the upper-left corner of the modeling window to assist you in finding edges. Edges are color coded by type. Show and hide an edge type by toggling its corresponding checkbox on and off, or quickly isolate an edge type by clicking Only.
