• Evaluate > Check Model

  Use this tool to analyze a model (or portions of a model) for geometry that has particular characteristics. Depending on the options you choose, a report is generated describing the contents of a model and the results of the checks performed.

  See Prepare a model for import into CAD systems for a sample workflow.

• Evaluate > Continuity > Surface Continuity

  This tool checks the position, tangent, and curvature continuity between and within surfaces.

• Locators > Deviation Use these tools to check the maximum distance between surface boundaries in Alias to confirm the integrity of the model before transferring it to the target CAD system.
• Surface Edit > Stitch > Shell Stitch

  This tool enables you to create a valid solid model topology within Alias. Stitching surfaces within Alias creates a shell. When the shell is exported to a downstream (CAD) system, it includes an extra layer of information.

  The stitching process also identifies surface boundaries that exceed the prescribed tolerances. The designer can correct these problems before translating the data.

  TipSave the original model before stitching.
  TipStitching is not required before transferring Unigraphics , Pro/ENGINEER, or CATIA files. If the geometry is stitched, it comes into the target system with topology information. If it is not stitched before transfer, the geometry comes into the target system as NURBS geometry.
