Stitch Surfaces

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

1. From the Geometry ribbon, Stitch tool group, click the Stitch Surfaces tool.

2. Optional: On the guide bar, click to define stitch options.

   Stitch methods include:

   Stitch and intersect

   Finds intersections between overlapping surfaces, creates trimming lines at the intersections, and equivalences the resulting surface edges.

   Stitch edges only

   Performs equivalencing of edges within surfaces or/and between surfaces. Further options like stitch free edges or stitch edges between components or across components are available to control stitching between edges.

   Use Parasolid

   Use Parasolid kernel to stitch edges. This option works on free edges only and not on non-manifold or T junctions. In addition, only surface selection is supported – clicking and dragging edges or points has no effect. This option is useful for locally merging edges that are less than 10 times the geometry cleanup tolerance.

3. Stitch or unstitch surfaces in the following ways:
   • Select surfaces to stitch in the modeling window then click Stitch on the guide bar.
   • 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.
   • 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.
