Learn how to get the topology correct for solid modeling.

Previous: Learn about the tolerance requirements for Solid Modeling

The Surface Edit > Stitch tools in StudioTools creates a valid solid model topology.

• Stitching surfaces can greatly improve the data transfer to a solid modeler.
• The stitching process also identifies surface boundaries that exceeds your tolerances.
• The stitching process identifies duplicate surfaces in the model and orients the surface normals of the completed shell.

The following illustration shows three individual surfaces (labeled S1, S2 and S3). The edges of each surface are represented by dashed lines.

When models are constructed using the StudioTools advanced surface tools (Swept, Rail Surface and Square), it is common to create a number of smaller surfaces along the edge of one larger surface. This modeling technique does not create the twin edges required for a solid model. Stitching fixes this.

Note

Some modeling techniques, such as Trim, Intersect and Round, create twin edges.
