To determine the geometric properties of an object when it is imported from Process
- DPM first searches for its representation in the graphicname_alt1 attribute. If this attribute is not
empty, it will provide a DPM-defined representation of the object (such as CATPart, model, CATProduct, CGR
- If no such representation exists in the graphicname_alt1 attribute,
- For a product: the CAD File attribute is then queried. This attribute is used for representation
supported by Process Engineer (CGR, JT, etc.) of the product.
- For a resource: the graphicname attribute is then queried. This attribute is used for representation
supported by Process Engineer (CGR, JT, etc.) of the resource.
- If no representation is found, the product/resource is represented as an empty node on the PPR tree with no
graphical representation in the 3D viewer.
DPM uses the value of this attribute to load the geometry of the entity. The object
will then be loaded:
In the example below:
- When Part 1 was brought into DPM, the graphicname_alt1 attribute was found to be empty, but the CAD
File attribute defined a CGR as its representation. This can be seen via the Manage Representations dialog
When Part 2 was brought into DPM, the graphicname_alt1 attribute defined a
CATPart as the graphical representation of the product. Therefore, the part and its sub-assembly can be seen in
the PPR tree (highlighted in the blue box).
When defining the graphicname_alt1 attribute in Process Engineer, either an
absolute path or a relative path may be defined.
An absolute path specifies the full path to the graphic representation, as shown in the example below:
When a relative path is specified, the root path is taken from the current
cadpath and product_cadpath
settings in Process Engineer:
The relative path specified for the graphicname_alt1 attribute is appended to the path defined for
cadpath and product_cadpath to locate the graphic representation. The following example of a relative
path would then resolve to:
When loading geometry defined with
relative paths, either of the following conditions must be satisfied:
- The values of the
variables each have a trailing backslash ("\") character, or
the relative pathname for the product/resource geometry begins with a
- The values of the
variables each do not have a trailing backslash ("\") character,
and the relative pathname for product/resource geometry does not begin
with a backslash character ("\").
Geometry will not be successfully generated in the V5 cache in the
event that (a) the values of the
product_cadpath variables have a trailing backslash character at
the end and (b) the relative pathname for product/resource geometry
begins with a backslash.
If a resource has a work system component associated with it, the geometry of the
work system component will be loaded in DPM when the resource is loaded in DPM. The following geometry formats
