Functional Description

Common

Defines the general settings including tessellation (arrangement and density of the polygons)

Geometry: Defines the geometry settings

  • Import Hidden Objects: Imports all hidden objects. If you modify any visible objects that contain hidden subobjects after import, those hidden objects are also modified.

  • Display Hidden Objects: Displays all hidden objects in the viewport after importing the file

  • Import Metadata: Imports file metadata from the original CAD file (stored inside the file as the metadata category CADMetadata)

Tessellation Settings: Defines the tessellation settings

  • Import Splines, Surfaces and Solids: Determines whether splines, surfaces, and solids are imported

  • Tessellation Level: Applies different resolutions based upon preselected values for chord height ratio and normal tolerances. If you select User-Defined, further options become available.

    • Angular Tolerance: Determines the maximum angular deviation (in degrees), allowed between an analytical surface and its triangulation. Pairs of triangles do not incorporate a dihedral angle greater than this amount. For example, this setting dictates the minimum number of facets around a smaller circle or cylinder regardless of the Surface Deviation setting. This parameter gives you added control over faces with small radii. Lower values result in finer tessellations, while higher values produce coarser tessellations.

    • Chord Height Tolerance: The value between the analytical surface and its triangulation that determines the distance and accuracy of the tessellation. The lower the value, the more accurate the result. 0.00001 is the minimum unit (high detail), and 1 000 000 is the maximum unit (low detail).

    • Chord Height Behavior: Determines how accurately the chord height tolerance is applied. Absolute applies the chord height tolerance as it is. Scaled adjusts the values depending on the scale of the object being tessellated.

PMI: Defines settings for PMI

  • Import PMI: Imports any Product Manufacturing Information (PMI) within the file. You can access the PMI data objects from within the 3D Objects list.

  • Import Model Views: Imports any custom model views within the CAD file. You can filter model views associated with different levels of the scene tree. The default setting is Top-Level.

    • All: All model views associated with parts, assembly including top-level assembly are imported

    • Top-Level: Only model views for top level (root) assembly are imported

    • Assembly: Only model views associated with assembly nodes are imported

    • Parts: Only model views associated with part (leaf) nodes are imported

    • None: Model views are not imported

Geometry Transformation
Transforms (rotate, position, and scale) the scene along the X, Y, and Z axes:

  • Rotation: Sets the degrees of rotation around each axis from 0 degrees to 360 degrees. The rotation values can be entered with up to 6 decimal places.

  • Scale: Scales the object along the X, Y, and Z axes

  • Position: Sets the position of the scene along the X, Y, and Z axes
