The DXF attributes, a set of group codes common to all entities, are mapped to Cimatron attributes as follows:
Entity Handle (group code 5).
A unique, permanent entity identifier. This attribute is ignored.
Layer (group code 8).
The name of the layer on which the entity resides. Layer is mapped with the Cimatron Level attribute as follows.
When no layer is specified, Cimatron 'LEVEL0' is assigned.
When the layer name exceeds 6 characters, the Cimatron Level will be assigned an abbreviated name, containing the first five characters of the DXF layer name, followed by a sequential number.
For example, mapping the following DXF layers gives these results:
TOP-VIEW®TOP-V1
SIDE-VIEW®SIDE-2
Color (group code 62).
Color is mapped with the Cimatron Color attribute through the parameters file. Color may also be mapped with Cimatron Pen Attribute through the parameters file.
Linetype (group code 6).
Linetype is mapped with Cimatron Line-Font attribute through the parameters file.
Extrusion Vector (group codes 210, 220, 230).
A 3D vector describing the Z axis of the ECS (Entity-associated Coordinate System). It is mapped with the Cimatron rotation pointer using the arbitrary axes algorithm (refer to the AutoCAD® Customization manual).
Elevation (group code 38).
The Z distance above or below the XY plane of the ECS. Exists only in DXF versions prior to 11.0.
Thickness (group code 39).
Extrusion amount from ECS in the positive direction of the ECS Z.
Space Flag (group code 67).
When the DXF space flag = 1 (paper space), the entity will be created in the Drafting application, otherwise it will be created in the Modeling application.
