[Closed] Using the Edit_Mesh modifier

Hi,

how can I use the Edit_Mesh modifier to edit the geometry of an object?

I started to create a modifier plugin based on the Edit_Mesh modifier:

plugin modifier myEditMesh
 	name:"myEditMesh"
 	classID:#(0x209ccfad, 0x553ff5d2)
 	version:1
 	[b]extends:Edit_Mesh[/b]
 	replaceUI:true
 (
 ...) 

but it refuses to apply any change of geometry using the mesh() and the meshOp objects. It only worked if the base object was an Edit Mesh object, but the changes were applied to the base object, not to the modifier.

Does someone knows a solution or a tutorial on that topic?

Thanks in advance,
Chris
