Import Model Settings

CAD models can be imported using the Geometry command in the Ribbon in the Home and Modeling tabs.

Commands

The following options appear in the Import model task pane.

Name Description
Uri Location of file.
Structure When importing a custom part or single component use Feature or Node. Or when importing a 3D geometry file that is a layout or factory line use Component which will add items to the layout as separate components.
  • Feature: The assembly tree structure goes to the feature tree of a component.
  • Node: The assembly tree will be mapped to a node tree of a component.
  • Layout: The immediate level of the assembly tree is imported as a new component.
Tessellation quality Defines the level of detail for rendering geometry using triangles and the number of polygons in the faces with curved edges. A low number generates high-performance and light-weight models, while a higher number offers better visualization. Recommended polygon (triangle) count limit for a static component is less than 100,000. Pay special attention to dynamic and/or moving components.
Extra low: 80 polygons
Medium: 272 polygons
Extra high: 528 polygons
Include Define what to include with geometry. If you include points, they will be imported and generated as Frame features.
Material Creation Rule Define rule for mapping the materials of geometry with those in your materials libraries.
Feature Tree and Organize geometry below affect the root node of the part you are importing.
Feature Tree Define what hierarchy to use for geometry. If Full is selected, an attempt will be made to match the structure of the model when viewed in its native CAD editor.
  • Full creates feature tree based on CAD's assembly tree, meaning that each item in the assembly tree will be it's own feature. A feature containing geometry generates a geometry feature, otherwise a transform feature.
  • Optimized generates a flat structure of feature tree, without extra transform features.
  • Collapsed creates only one geometry feature.
Organize geometry Defines how the geometry will be organized into geometry sets. Geometry sets can be sliced, exploded, or collapsed. Use By material or Collapsed as default.
  • By faces* will make each face as own geometry set. This is not recommended unless needed for specific topology use cases.
  • By material option creates own geometry set for each color in a single mesh. Some CAD formats can define different colors in different faces in a single mesh, but in Visual Components there can be only one material per geometry set.
  • Collapsed combines all the meshes into one geometry set. However, to optimize the performance, a new set will be created when the total amount of triangles exceeds 10,000 (or 16,000 points).
  • Mathematical data* will organize geometry one set per face and store a BREP entity in a triangle set creating a larger geometry and file size. Used for special scenarios, for example when special accuracy is needed in robot offline programming.
    *NOTE: Only use if really required!
Up axis Define axis for aligning top and bottom of geometry.
Minimum hole diameter Define tolerance for removing holes in geometry.
Minimum geometry diameter Define tolerance for not importing set of geometry based on its minimum bounding box.
Healing tolerance To connect points, lines and edges in the file's geometry, in Healing tolerance, set a distance value. Generally, this setting is used as a cleanup tool for fixing holes, cracks and gaps that occur on the faces of solid objects. If the distance value is zero, cleanup is disabled. If the distance value is greater than zero, vertices that neighbor one another, and are within a range set by the distance value, might be connected to one another by generating a new line.
Units Works with some CAD formats (U3D, CGR, STL, VRML) to handle unit conversion for scaling purposes, in Units, select the unit of measurement used in the file. If Default is selected, it is assumed the unit of measurement is the same as the one currently used in Visual Components Premium 4.9
