This applies to xm & v8i Bentley Architecture and AECOsim Building Designer
Starting in the v8i Dataset for Bentley Architecture, we shipped counter sinks with a perforator to cut the countertop, but there is a trick to using them.
The schematic casework tool places countertop as a short fat linear form. Because of a programing change in xm, you can not cut the top of a linear form with a perforator. (you can in v8 2004 and you can now in AECOsim Building Designer Updage 1, if you set the configuration variable: BB_PERFORATEWALLTOP = 1 )
For XM, & v8i Bentley Architecture and the initial release of ABD, This means you need to place your countertop as a slab. This is easily done using the Place Curve Form tool. This tool will place a compound wall (which is what the schematic casework really is) as slabs instead of linear forms.
To place a schematic countertop with the Place Curve Form tool:
To place the sinks:
The perforator should automatically cut the opening in the countertop.
