Hole Group Reference
Hole group in component parts, here mainly in component part groups, get further reference dimensions in addition to the standard add-on dimensions of sub-parts. In this example, a connecting butt strap is dimensioned with reference to the holes.

Add-on Dimension in Component Part Group
The butt strap is dimensioned with reference to the connecting shape, here to its insertion reference point.
-
The connecting shape is selected for hole group reference as well.
-
Alternatively, the hole group reference can also be made to the first hole (3) or to the last hole (4).
The drill holes are always dimensioned with relative dimensions at hole group reference, selection of coordinate dimensions, however, influences the dimension of hole group reference (2).
Gusset-Plate Dimensioning
Drill holes in gusset-plates of component part groups can be dimensioned as displayed in the example. In most cases, this dimensioning serves for drawing control, if single part drawings are generated.
-
Here, the reference point of dimensioning is the edge of the plate. In addition, the dimensioning chain is completed to the system point (3).
-
Here, the reference point of dimensioning is the system point (3); however, a reference to the edges of the plate is possible as well.
The defaults are displayed as additional entry in the selection list for component part types of group dimensioning and therefore can be attached in addition to standard dimensioning of poly-plates.
