explodeEMesh $

here are some things for you.

this fn will return an objects elements as an array or arrays:

fn getelements obj=
(
	try
	(
		f=obj.numfaces
		eles=#()
		done=#()
		for i=1 to f do
		(
			if (finditem done i)==0 then
			(
				case (classof obj) of
				(
					editable_mesh:(faces=(meshop.getElementsUsingFace obj #(i)) as array)
					editable_poly:(faces=(polyop.getElementsUsingFace obj #(i)) as array)
				)
				append eles faces
				join done faces
			)
		)
	)
	catch(eles=undefined)
	return eles
)

this routine will detach faces based on a threshold. Use a threshold of 180 to detach by element.

obj=selection[1]
while obj.faces.count>0 do
(
	newmesh=editable_mesh()		 -- create an empty mesh object
	newmesh.pos=obj.pos		 -- position the new mesh
	newmesh.name=(obj.name+"_"+(i as String))	 -- name the new mesh
	fce=(meshop.getpolysusingface obj #(1) threshold:100) as array
	newmesh.mesh=meshop.detachFaces obj fce delete:true asmesh:true
	update newmesh		 -- update the new mesh
	update obj			-- update the old mesh
)

create yourself a frankenstein if you like or use Merlins exemplary code.

wooha , thanks for help , i apreciate it

j-man
lots to see in yourr code , naming …also …hehe …thanks …

one more technical ques.
i’ve seen a lot of fragmentation scripts based on slicing , caping … and i’m working on my
own lame version here , but the original idea i was thinking of is using procutter fro the
fragmentation … anyone tried that before and got good results with it ?
i mean based on slicing … its always random Slice_Plane.ROt …and pos …
anyone did a procutter fragmentation version with neat results ?
