How do I remove mid-edge EPoly Vertices?
A user asked:
I want to filter the edge selection and create arrays containing connected edges,
something like "edge selection elements". Edges from two arrays will never be connected,
in other words will not share vertices.
Answer:
The following code implements a possible solution:

macroScript KillMidEdgeVerts category: "MXS Help"
(
on isEnabled return
selection.count == 1 and classof selection[1].baseobject == Editable_Poly
on execute do
(
thePoly = selection[1] --get the selected object
select thePoly --select it
max modify mode --switch to modify panel
--set the base object as current level:
modPanel.setCurrentObject selection[1].baseobject
subObjectLevel = 1 --set sub-*object level to vertex level
numVerts = (polyop.getNumVerts thePoly) --get the total vertex count
undo on "KillMidEdgeVerts" --enable undo context
(
--loop backwards from the last to the first vertex
for v = numVerts to 1 by -1 do
(
--get the edges using the vertex to check the count
nVerts = (polyop.getEdgesUsingVert thePoly v) as array
if nVerts.count == 2 do --if only two edges found, then
(
--get the verts of the first egde
edge1verts = (polyop.getVertsUsingEdge thePoly nVerts[1]) as array
--calculate the vector defined by the two vertices in the first edge
vector1 = (polyop.getVert thePoly edge1verts[1]) - (polyop.getVert thePoly edge1verts[2])
--get the verts of the second edge
edge2verts = (polyop.getVertsUsingEdge thePoly nVerts[2] as array)
--calculate the vector defined by the two vertices in the second edge
vector2 = (polyop.getVert thePoly edge2verts[1]) - (polyop.getVert thePoly edge2verts[2])
--calculate the angle between the two normalized vectors
angle = acos (dot (normalize vector1) (normalize vector2))
--if the angle is less than the threashold (change 0.01 to whatever threashold you want!)
if angle < 0.01 do
(
select thePoly.verts[v]--then select the current vertex
thePoly.EditablePoly.buttonOp #Remove--and hit the remove button
)
)--end if
)--end v loop
)--end undo
)--end on
)--end macro
