csWorkPlane v1.52 - Align Workplane to FaceSelection


This script only works on Mesh Faces. How to add Poly Faces? Unfortunately, I don’t know coding, I will be grateful if you could help me. Thank you!

macroScript AlignWorkplaneToFaceSelection category:"csTools" tooltip:"AlignWorkplaneToFaceSelection"
macros.run "csTools" "RemoveWorkPlane"
fn placeGridOnSelectedFace = (
	local o = selection[1]
	local omesh = o.mesh
	local totalPos = [0,0,0]
	local totalNormal = [0,0,0]
	local selFaces = omesh.selectedFaces
	if selFaces.count > 0 then (
		for fc in selFaces do (
			totalPos = totalPos + (meshop.getFaceCenter omesh fc.index)
			totalNormal = totalNormal + (meshop.getFaceRNormals omesh fc.index)[1]		
		local center = totalPos/selFaces.count		
		local normal = totalNormal/selFaces.count

		local selVerts = ((meshop.GetVertsUsingFace omesh selFaces) as array)
		local firstEdge = normalize((meshop.getVert omesh selVerts[2])  - (meshop.getVert omesh selVerts[1]))
		local xaxis = cross normal firstEdge
		local yaxis = cross  normal xaxis
		local gridTm = (matrix3 (normalize xaxis)  (normalize yaxis) normal center)
		local worldTM = gridTm*o.transform

		global workplane = (grid name:"workPlane" grid:10.0)
		format "-- Genrating WorkPlane.\n"	
		workplane.width = workplane.length = (distance o.min o.max)
		workplane.transform = worldTM
		local tmpSelection = (selection as array)
		select workplane
		max activate grid object
		select tmpSelection
		toolmode.commandmode = #ROTATE 
		toolMode.coordsys #grid			
		toolmode.commandmode = #USCALE
		toolMode.coordsys #grid		
		toolmode.commandmode = #MOVE 
		toolMode.coordsys #grid				
		messagebox "Select face(s) on an object"
if selection.count == 1 and (canConvertTo selection[1] editable_mesh) == true then (
	messagebox "Select a Face on a Mesh"

I think should change these pieces to “Poly.” but … not working :confused: polyOp/opoly

local omesh = o.mesh
(meshop.getFaceCenter omesh fc.index)
(meshop.getFaceRNormals omesh fc.index)[1]
((meshop.GetVertsUsingFace omesh selFaces) as array)
normalize((meshop.getVert omesh selVerts[2]) - (meshop.getVert omesh selVerts[1]))
(canConvertTo selection[1] editable_mesh)
