IGES files normally contain only surface definitions and no solid geometry. Therefore it is necessary to sew surface definitions to form a solid body.

Healing involves preparing the free surfaces for stitching.  Solid Edge cleans the faces to resolve underlying problems such as self-intersection, multiple intersections, or edges equal to or smaller than the minimum stitching tolerance. Once the faces are cleaned, Solid Edge identifies and removes sheets that are invalid due to bad trimming curves, or sheets that result in slivers.

Once the sheets have been cleaned, Solid Edge stitches any remaining gaps and fills holes where possible, using surfaces that were removed during pre-processing.  After the stitching process, Solid Edge identifies missing geometry due to surface errors during translation.  New surfaces are created where possible using adjacent surface edges.

Healing prepares solids by resolving such issues as self intersections, tolerant edges, and topology problems.

Actions on Import

Specifies how you want to format the imported file.

Do Not Heal or Stitch Free Surfaces

Specifies that you do not want to heal or stitch any free surfaces.

Stitch Free Surfaces (Create Solid Body)

Specifies that you want to stitch the free surfaces to create a solid body.

Heal and Stitch Surfaces (Create Solid Body)

Specifies that you want to heal and stitch free surfaces to create a solid body. When given a set of sheet bodies the software cleans the input sheets of self intersections and loop inconsistencies. It then identifies and removes very small surfaces or sliver sheets from the set of sheets. Edges of adjacent surfaces are then used to fill holes where slivers were removed. Larger holes from missing surfaces are also filled. After the healing process is complete a single stitch operation at 1.0e-5 (meters) is attempted to create a solid body.

Boolean Solids

Specifies that you want to boolean all solid bodies together to form a disjoint solid and inserted into PathFinder as a part copy. This option is on by default.  If the option is off, all solid bodies are added as individual part copies to PathFinder.

Body Check

Specifies that you want to perform a full body check on the file. This option is off by default.

Imprint Curves

Specifies that you want to combine all curve data into a single part copy. It may be to your advantage to identify the curves that you do not need and either hide or delete them before importing the file. This option is on by default.

Create Base Feature

Specifies that you want to make the imported solid body the base feature for the Solid Edge model. If there is more than one solid body in the Parasolid (.X_T) file, no base feature is created. In this case you can use the Make Base Feature command to select a solid to use as the base feature or construct a new base feature for the model.

If you clear this option, all solid bodies contained in the IGES (.IGS) file you are importing are placed in PathFinder as a part copy rather than a body feature. Inserting bodies as a part copy requires you to select or create a base feature.

Stitch Tolerance Iteration

Defines stitching tolerance information used in the stitching process.

Start At:

Specifies the starting value for the stitch tolerance.

End At:  

Specifies the ending value for the stitch tolerance.

Incremental Factor:

Specifies a factor by which the stitching tolerance is incremented during the stitching process. This value must be greater than 5 and has no upper limit.

Values At Which Stitching will be Attempted:

Displays the tolerance values at which Solid Edge attempts to stitch the surfaces into a valid solid body.  These values are obtained by multiplying the stitching tolerance for the previous attempt by the increment value.  For example, suppose you have a Start At: value of 1.00e-006 and an Increment Value of 10.  On the first attempt, Solid Edge will try to stitch the surface at the Start At: value of 1.00e-006. On the second attempt, the tolerance value on the previous attempt of 1.00e-006 is multiplied by the Increment Value of 10, resulting in a tolerance value of 1.00e-005.  On the third attempt, the tolerance value on the previous attempt of 1.00e-005 is multiplied by the Increment Value of 10, resulting in a tolerance value of 1.00e-004. Solid Edge will continue this until it can successfully stitch the surfaces or until it reaches the End At: value.
