Geometry Filters – Planworks Support Center

Geometry Filters (Scope Box & SolidFilter)

The Geometry Filter spatially restricts the element set of a rule. Only elements that are inside or intersecting the filter area will be processed.

Filter Types

Scope Box (Revit Standard)

Scope Boxes are rectangular volumes defined in Revit. All Scope Boxes in the project automatically appear in the Geometry Filter dropdown of a rule.

SolidFilter (b.i.m.m Extension)

SolidFilters allow more complex geometric filter shapes – e.g. based on room contours or arbitrary volumes. They are defined in the separate b.i.m.m SolidFilterTool and stored in the Revit document. Rooms and Parts are handled separately when using a SolidFilter to ensure correct filtering.

Geometry Filter Mode

Mode	Condition	Typical Use
Inside	The element's Bounding Box must be fully within the filter area	Furniture, fixtures clearly assigned to one area
Intersects	It is sufficient if the element touches or intersects the filter area	Walls, columns, slabs that cross area boundaries

Tip: For walls that often extend beyond a Scope Box boundary, use Intersects. For clearly bounded elements like furniture, Inside is more precise.

Special Categories and Geometry Filters

Category	Behavior
Views	Geometry filter is ignored
View Templates	Geometry filter is ignored
Stair Runs	Geometry filter is ignored
Stair Landings	Geometry filter is ignored

Important when loading Shortcuts: If a rule references a Geometry Filter not present in the current project, the error "Scope Box not found (Row X)" appears. The rule is loaded without a filter – which may produce unintended results. Always verify the filter manually in this case.
