We have a Wall Penetration that is incorrectly cutting an adjacent slab. We've set the PAZ Penetration cell to be uni-directional (-1) and have set the Sense Distance to less than the Wall Thickness, but the problem persists. How can we force Wall Penetrations to only affect the walls in which they're placed and not the underlying slab?
In order to have the perforator result in a specific defined cut depth, the Blind attribute in PC Studio must be set to "True". The following information was taken from the Parametric Cell Studio Reference Guide: Model Segments & Properties > Element Properties, Attributes and Operations > Attributes Used by Bentley Building Applications > Attributes Used for Openings (Perforators):
Possible Values: True or False (selected from the drop-down list box when Boolean is selected for Type)
The Blind attribute controls the depth of the cut with respect to the Sense Distance. If the Value assigned to Blind is False, the RoughOpening Perforator will cut all the way through any forms found within the Sense Distance. If the Value of Blind is True, then the RoughOpening Perforator will only cut to the depth of Sense Distance. This option can be used to cut pockets into forms for recessed cabinets, sliding doors etc.
Two additional perforator attributes defined in PC Studio are:
Possible Values: 2, 1, or -1
The Directional attribute controls the direction of the cut from the RoughOpening path when the cell in placed in Bentley Architecture. If the Value of Directional is 2, then the cut will be 2 way, that is, it will cut in both directions perpedicular to the plane of the path. If the Value of Directional is 1, then the direction of the cut will be outward from the path. If the Value of Directional is -1, then the direction of the cut will be inwards from the path. For use in Doors and windows, the logical value of Directional will be either 2 or -1.
Possible Values: any length value.
Sense Distance is the distance which Triforma will search from a perforator for elements to cut. The SenseDistance attribute contains the default value you wish to apply to the Triforma Sense Distance search. This value can be modified in the tool dialog at placement time or in the Perforators tab of the Triforma Element Info dialog when a Parametric Cell os selected.
