Advanced CAD Import Options

View the advanced geometry options available for import (depending on the type of file to be imported).

Units
Source file unit
The unit of the source file to be imported.
CADFEKO model unit
The unit of the CADFEKO project.
Healing options
This option controls the healing of data containing performance-expensive errors.
  • No healing
    • No healing is applied to the imported file.
  • Standard healing / Advanced healing
    • Geometrical and topological irregularities are repaired and healed. The translated file is scanned for corrupted data and invalid data is fixed.

      If the imported model contains face-face inconsistencies, it will cause multiple separate parts to be created during the healing process. After importing, use the union or stitch operation to combine the parts into a single part.

      Note: The advanced healing option adds a few more time consuming and extensive healing operations to the conversion process.
Simplify model
This option controls the process of cleaning and removing redundant topologies and geometries from the model during translation. If a vertex is redundant, the vertex is deleted and the associated edges are merged. If an edge is redundant, the edge is removed and the associated faces merged.
Stitch trimmed faces
This option controls the stitching of trimmed1 faces during the translation process.
Use two step import process
Some models may not import correctly with the current import process. Use the two-step import process that makes use of the older, legacy import process to attempt to import problematic models.
Extrude
Enables the extrusion option (only for .dxf file imports).
Auto-stitch faces
Faces that touch are automatically stitched (only for .dxf file imports).
Auto-merge wires
Wires that touch are automatically stitched (only for .dxf file imports).
Scale by
When the source file is imported, the imported model is converted to metres as an intermediate step during the import process. The Scale by factor is then the conversion from meters to the CADFEKO model unit.

For example, if the source file unit is in mm and the CADFEKO model unit is in cm, the scale factor should be 100.

1 A trimmed surface is a surface which was divided into multiple pieces as a result of a modelling operation. A portion of the surface may no longer be required to support the model topology. The redundant pieces are then discarded.
