Creo Parametric (Pro/ENGINEER) Assembly File

Use

You can import and view Creo Parametric (Pro/ENGINEER) Assembly (.asm) files.

Supported

  • Hierarchical structured Scene Tree

  • Combined views (user-defined model views in CREO software)

  • File properties, Model properties

  • Object Attributes: Color, opacity, visibility

  • Mesh or Solid Import:

    • Tessellation control option with mesh import and dynamic tessellation option for solid import

    • Normals and UV coordinates

  • Functional Dimensioning & Tolerancing (Notes, Driven, and Reference Dimension, Tolerances, surface finish)

  • Import of Construction geometry; for example, Points, Coordinate Axis, Surfaces, Curves, Wireframes

  • PMI to surface highlighting and PMI to Edge highlighting

  • Limited support of Assembly level features

  • The latest version of any part file within the folder is always opened. For example, sprng.prt.3 opens if the folder contains spring.prt.1, spring.prt.2, and spring.prt.3.

  • Creo (Pro/E) searches through folders for part and assembly files and for corresponding accelerator files in the:

    • Current directory of the file

    • Search paths specified in the CAD Modules tab

  • If a part, assembly, or accelerator file isn’t found, and logging is enabled, the information is logged in the application that you’re using.

  • PMI (Functional Dimensioning & Tolerancing, Geometric Dimensioning & Tolerancing)

Limitations and Restrictions

  • Animation

  • BoM support based on part names

  • Not all assembly level features are supported.

  • Textures

  • Some transformation issues with GDT PMI in both part and assembly where PMI isn’t attached to any 3D geometry

  • To represent text and symbols for FD&T and GD&T, Visual Enterprise software uses its own RHGDT font. All monospace fonts are replaced by Roborto.tff. Text and Symbol display a different size and shape.

  • No support of Persistence Identifier and CAD Identifiers

  • No support for connection points

Features

This format contains import options. You can use them to customize the way in which your file is opened.

Import Interface

Field

Functional Description

Common

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

Geometry: Defines the geometry settings

  • Import Filters: Defines the import filter 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 don’t 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 Captures Model Views: 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 file.

Construction Geometry: Defines settings for the construction geometry

  • Import Axis Systems: Imports and draws axis systems as defined in the CAD file. There may be one or more axis systems defined in the CAD file, for one or more nodes.

  • Import Surfaces: Imports all construction geometry

  • Import Points: Imports all 3D point data stored inside the CAD file and draws points as saved in CATIA files.

  • Import Wireframes: Imports all wireframes if any exist.

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
