Select bottom polygons of a editable poly box help

Hi.

I have a editable spline that I enable the rendering as retangle and then I convert to editable poly, that I need to select the bottom polygons of, invert the selection and then delete the selected polygons.
But I have no clue of how to make the selection part.

SOLVED

Thanks too. I was having the same issue. If it doesnot work I will make the following.

Give them a very high depth like 20m or 200m so I can select in poly edit mode from teh side view and delete al the faces selected and I hope only the top faces will be left.

EDIT: solved

finally!!

I've not used the scritp provided but found a workarround. I use this for road pavement lines. Import from your cad file. MERGE SAME SPLINE TYPE PER LAYER. this will speed up importing specially if you've lots of them.

Mesh rendere with rectangular rendere with zero heigh, planar.

Apply EDIT MESH modyfier

Select per faces. aaand

CHEKCK ignore backfacing.

Place yourself in botton view (if you want to delete botton side)

Rectangle selection

ONLY botton faces are selected.

Elete.

DONE!!

Delete "Cap Faces" from converted Splines

Select your converted splines and run this code
(works on E-Poly and E-Mesh)

fn deleteCupFaces =
(
	if selection.count != 0 do
	(
		--call polyop and meshop function before start for-loop
		local delPoly = polyop.deleteFaces, delMesh = meshop.deleteFaces
		for obj in selection do 
		(
			local fC = getNumFaces obj -- get number of Faces for each item in selection
			if isKindOf obj Editable_Poly then (delPoly obj #{(fC-2)..fC} delIsoVerts:true) --E-Poly method
			else if isKindOf obj Editable_Mesh do (delMesh obj #{(fC-3)..fC} delIsoVerts:true ; update obj) --E-Mesh method
		)
	)
)
deleteCupFaces()
