[Closed] Zero face selected and deleted script

Oct 17, 2008 9:22 am

I am working on a 3ds max project and this time, require rule is no zero face – is a triangle that has all vertices in a straight line. Modeller sometime snap and make mistake so leave the face alone.

So I am writing a small script trying to check the whole model, selected and delete them all.

Could anyone help me with this snippet

Thanks for any help

I think I would calculate the polygon surface area, if it’s below a certain small value put it up for deletion.

thanks but could you give me a snippet, that will be a great help

I am not a Max user so doesnt have foundation of max and max script. All I could do is try to understand the code and embed it into tool.

something like this… slightly inefficient as it could collect the tiny faces and then delete them all in one go, but it’s a good start %)

only works on editable mesh / editable poly objects… if it needs to be done on an edit poly modifier, I think additional code is needed.

control the minimum face size with the ‘threshold’ value


(
	threshold = 3.0
	if (classOf $ == Editable_mesh) then (
		for i = $.numfaces to 1 by -1 do (
			if ((meshop.getFaceArea $ i) < threshold) do (
				meshop.deleteFaces $ #{i}
			)
		)
		update $
	)
	else if (classOf $ == Editable_Poly) then (
		for i = $.numfaces to 1 by -1 do (
			if ((polyop.getFaceArea $ i) < threshold) do (
				polyop.deleteFaces $ #{i}
			)
		)
		update $
	)
)
