About the Semantic Import of Dimensions with PMI Data from Creo Elements/Direct
When you import Creo Elements/Direct Modeling files, the linear, radial, diameter, and angular dimensions of part and assembly models are transferred as semantic representations. The import also includes 3D notes.
The Product Manufacturing Information (PMI) of the dimensions and notes is preserved and is semantically transferred. Dimensions and notes with their references and the PMI content are included in the annotation features of the imported models. You can, therefore, redefine the PMI references after you import the Creo Elements/Direct models.
You can semantically import dimensions that lie between vertices, edges, and faces. In the following cases, however, the original references of the dimensions are not retained and dimensions import with vertices as references:
• Dimensions lie between edges that are perpendicular to the annotation plane.
• Dimensions lie between inclined faces.
• Dimensions reference edges that are inclined to the docuplanes.
• Dimensions have overlapping references.
When a dimension references the mid-point of an edge that is perpendicular to the docuplane, the import of the dimension creates a reference feature point at the mid-point of the edge.
Free dimensions and notes are also imported as semantic representations. Each free dimension is created on a separate datum plane for its placement and orientation after import. To view the free dimensions and notes after import, you must select the corresponding combined view.

When you import or open *.pkg files, notes on models with attachment points that exceed 200 points are imported or opened as graphical representations in Creo Parametric.

Dimensions that reference wire parts are imported as semantic representations.
Ordinate dimensions are imported as linear dimensions. Coordinate dimensions are imported as individual linear dimensions.

Dimensions created in a configured state in Creo Elements/Direct do not import properly to Creo Parametric.

When angular dimensions reference a coordinate system axis in Creo Elements/Direct, the import creates a coordinate system axis as the reference for the imported dimensions. When the angular dimensions reference a plane of the coordinate system in Creo Elements/Direct, the import creates a datum plane as the reference for the imported dimensions.
When linear dimensions reference a cylinder where the cylindrical axis and the docuplane normal form an acute angle, a datum point is created and used as the reference instead of the cylinder during the import of the linear dimensions. Radial and diameter dimensions that reference the cylinder are imported graphically when the cylindrical axis and the docuplane normal form an acute angle.
When you import Creo Elements/Direct Modeling files, the annotation planes that Creo Elements/Direct uses to position dimensions and notes are preserved. Docuplanes are imported as datum planes and used as reference planes to place the imported dimensions and notes. The datum or the annotation planes are oriented with reference to the docuplanes so that the annotations are parallel to the viewing direction. The z-extension lines are automatically created in Creo Parametric when the linear and radial dimensions are on the offset plane.
Dimension arrows and dimension text are displayed with the appropriate font and arrow size after the import. Dimension text consists of the dimension value and can contain prefix, suffix, and the super and sub text. The placement of the notes, the text and font of the notes, and the leader type of the notes are preserved.
