ArchiModellingTools¶

General architectural modelling utilities — area/length measurement, layer management, display mode control, isolation tools, and block creation.

Measurement¶

knAreainSF¶

Calculates the total area in square feet (SF) of selected geometry and copies the numeric result to the clipboard.

Icon	Property	Detail
	Input	Select curves, surfaces, polysurfaces, meshes, or extrusions (preselect supported)
	Output	Prints total area (SF), valid/invalid counts; copies value to clipboard

knAreainSM¶

Calculates the total area in square metres (sq.m) of selected geometry and copies the value to the clipboard.

Icon	Property	Detail
	Input	Select curves, surfaces, polysurfaces, meshes, or extrusions
	Output	Prints total area (sq.m), valid/invalid counts; copies value to clipboard

knCheckElevation¶

Verifies the absolute Z-coordinate of selected objects or picked points, providing quick elevation checks for topography or multi-storey BIM models.

Icon	Property	Detail
	Input	Pick a point or select objects
	Output	Reports Z-elevation in the command line and adds a temporary visual marker

Layer Management¶

knHideLayers¶

Hides all objects that share the same layer(s) as the current selection. This is a powerful way to declutter the viewport based on object context rather than manually searching the layers panel.

Icon	Property	Detail
	Input	Select one or more objects (preselect supported)
	Output	All objects on the same layer(s) are hidden

knIsolateLayers¶

Isolates the layers of selected objects — hides all objects that do not share a layer with the selection.

Icon	Property	Detail
	Input	Select one or more objects (preselect supported)
	Output	Objects on all other layers are hidden

knRandomColorstoLayers¶

Assigns a random RGB colour to each layer. Can operate on all layers or a selected subset. Ideal for color-coding complex site models or imported CAD data.

Icon	Property	Detail
	Input	Option: All Layers or select specific layers
	Output	Each layer receives a random colour

knDeleteLayers¶

Deletes a named layer and all objects on it. Unlocks the layer first if needed, then purges it from the document.

Icon	Property	Detail
	Input	Type the layer name to delete
	Output	All objects on matching layers deleted; layer purged

Selection & Isolation¶

knSelAllGroups¶

Selects all objects belonging to any named group in the document.

Icon	Property	Detail
	Input	None
	Output	All grouped objects become selected

knIsolateGroups¶

Selects all grouped objects, then runs Rhino's Isolate to hide everything else. Useful for focusing on grouped assembly logic without the distraction of ungrouped "loose" geometry.

Icon	Property	Detail
	Input	None
	Output	All grouped objects isolated; ungrouped objects hidden

Blocks¶

knCreateBlock¶

Creates a new block definition from selected objects, using a three-point rectangle to define the block's local coordinate plane and origin. This ensures the block insertion point is exactly where you intend it.

Icon	Property	Detail
	Input	Pick 3 points for the local plane; select objects; enter block name
	Output	New block definition created; original objects replaced by instance

knEditBlockPlane¶

Redefines the local 0,0,0 and orientation axes of an existing block definition without moving the block instances in the scene.

Icon	Property	Detail
	Input	Select block instance; pick 3 points for the new plane
	Output	Block definition's internal origin/axes updated

knEditNestedBlock¶

Enables editing of a block definition that resides inside another block (nested). It "drills down" into the hierarchy, allowing for deep-edits without exploding the parent block.

Icon	Property	Detail
	Input	Select a sub-block instance
	Output	Opens the nested block definition for editing

knChangeBlockName¶

A productivity tool for bulk renaming block definitions across the entire Rhino document.

Icon	Property	Detail
	Input	Select block instance(s)
	Output	Prompts for a new name and applies it to the block definition

Display Modes¶

knSetObjectDisplayMode¶

Sets a per-object display mode override on selected objects. The user chooses from all available viewport display modes.

Icon	Property	Detail
	Input	Select objects; choose display mode from a list
	Output	Selected objects render in the chosen mode in the active viewport

knMatchObjectDisplayMode¶

Copies the per-object display mode override from a source object and applies it to all target objects. Perfect for quickly matching "ghosted" or "technical" looks across many objects.

Icon	Property	Detail
	Input	(1) Select target objects; (2) select source object to match
	Output	Targets inherit the source's display mode override

knRemoveDisplayModeOverrides¶

Removes any per-object display mode override from selected objects, reverting them to the viewport default.

Icon	Property	Detail
	Input	Select objects
	Output	Display mode overrides cleared for the active viewport

knWireframeDisplay¶

Toggles selected objects between a Wireframe override and their normal display mode.

Icon	Property	Detail
	Input	Select objects
	Output	Toggles wireframe override state

Geometry & Surfaces¶

knPlanarizeSurface¶

Tests whether a surface is planar. If not, it projects the boundary onto the average normal plane and recreates a perfectly planar surface.

Icon	Property	Detail
	Input	Select a non-planar surface
	Output	Generates a new planar version of the surface

knUVEdit¶

Opens a manual UV editing interface to coordinate texture mapping orientations.

Icon	Property	Detail
	Input	Select surfaces
	Output	Refines texture map projection and alignment

knCenterDivideCurve¶

Divides a curve based on a length parameter, keeping the division symmetrical relative to the curve's center. This ensures balanced "remainders" at both ends.

Icon	Property	Detail
	Input	Select curve; specify segment length
	Output	Points added at symmetrical division intervals

knaddContructionLine¶

Draws semi-infinite grey construction lines through two points for reference drafting.

Icon	Property	Detail
	Input	Pick two points
	Output	Reference line added to the document

Miscellaneous¶

knToggleGumballSnap¶

Toggles Rhino's Gumball Snappy mode on/off.

Icon	Property	Detail
	Input	None
	Output	Toggles snappy gumball state

knImportWorksessionFiles¶

Imports all worksession reference files into the current document as regular geometry.

Icon	Property	Detail
	Input	Confirm import of external 3dm files
	Output	Reference geometry becomes local geometry
