Poly:

Mesh:

MAXScript User Reference:

meshop.getVertsUsingEdge <Mesh mesh> <edgelist>

Returns a bitarray of size=(#vertices in mesh) with bits set for all vertices that are used by the specified edges.


 

macroScript Edge2VertSel category:"MXS Help"

(

--make sure a single EMesh object is selected

on isEnabled return 

selection.count == 1 and classof selection[1] == Editable_Mesh

on execute do

(

obj = selection[1] --get selected object

edgeSel = getEdgeSelection obj --get selected Edges

--get Verts of selected Edges:

vertsSel = meshop.getVertsUsingEdge obj edgeSel 

setVertSelection obj vertsSel --select the Verts

max modify mode --switch to Modify panel

subObjectLevel =1 --set Vertex SO level

)--end on 

)--end macro

Stright from the User Reference after 2mins of searching…

Thanks for your feedback but I had implemented similarly upto

 vertsSel = meshop.getVertsUsingEdge obj edgeSel

How do I get the point3 vector position (i.e. transform) for the vertsSel which is a bitarray or vertices.

I am trying to get the vector position of all three vertex in one face of a mesh. So that the vertices can be calculated using vectors.

For each element of the bitarray that is true, call getVert obj theIndex.

You could also convert the bitarray to array to get just the flagged vertices’ indices.

vertsSel = (meshop.getVertsUsingEdge obj edgeSel) as array
vertsPos = for v in vertsSel collect (getVert obj v)

Now, every element of the vertsPos array will provide the position corresponding to every selected vertex index in vertsSel array.

Thanks
