Repairing problems

SpaceClaim can import a variety of native and neutral CAD formats, but you may need to clean up and repair this data for use in SpaceClaim and for CAE. The Repair tab includes tools you can use to repair imported models and prepare your designs for export and analysis.

The Repair tools are presented in the following groups:

Solidify
Fix
Fix Curves
Adjust

In general, when you need to repair geometry imported from another source, you use the tools in the order they are presented in the ribbon (left to right).

Tools in the Solidify group fix problems that may exist in imported data, which prevent the model from being solid.

	Use the Stitch tool to combine surface part faces that are touching at their edges.
	Use the Gaps tool to repair gaps between faces.
	Use the Missing Faces tool to fill missing faces.

Tools in the Fix group fix problems that may exist in imported data, which can exist in a solid model but cause problems when you edit or modify the geometry.

	Use the Split Edges tool to remove extraneous points on edges.
	Use the Duplicates tool to detect and fix duplicate faces.
	Use the Extra Edges tool to detect and remove edges that are not needed to define the model.
	Use the Bad Faces tool to detect faces that have corrupt rendering.

Tools in the Fix Curves group fix problems that may exist in imported data, which cause problems when working with curves.

	Use the CurveIn 3D, any line in space. Gaps tool to detect and fix gaps between curves.
	Use the Small Curves tool to detect and remove small curves and fix the resulting gaps.
	Use the Duplicate Curves tool to detect and remove duplicate curves.
	Use the Fit Curves tool to improve selected curves by replacing them with lines, arcs, or splines.

Tools in the Adjust group help you modify characteristics of your design that will affect analysis.

	Use the Merge Faces tool to combine two or more faces into a single face.
	Use the Small Faces tool to remove small faces from your design.
	Use the Tangency tool to change nearly tangent faces so they are tangent.
	Use the Simplify tool to simplify complex faces and curves.
	Use the Inexact Edges tool to repair edges that do not fit together precisely.
	Use the Relax tool to reduce the number of control points in imported surfaces to make them more stable.
	Use the Straighten tool to straighten faces that are at unwanted angles.
