Hello
this is an add on which remove vertices which are not in at least 1 edge.
for example, when you have lots of hidden vertices alone and can’t use the remove doubles.
use it in edit mode ( ‘N’ ) but can easily rewritten to be used anywhere
Rem : use bmesh to remove vertices
I had just a problem with one version of blender I don’t remember which one maybe 2.65.
Unfortunatly, writing this, something happened and it doesn’t work any more as an addon
So I give at first the code you can use as a script ( alt P )
import bpy,bmesh
for obj in bpy.context.selected_objects:
if obj.type== 'MESH':
print('work '+obj.name)
bm=bmesh.from_edit_mesh(obj.data)
v=bm.verts
E=bm.edges
tmpv=[True for i in range(len(v))]#numeros des verts a detruire
for i in E:
tmpv[i.verts[0].index]=False#verts pas a detruire
tmpv[i.verts[1].index]=False#verts pas a detruire
adetruire=[]#liste des numeros des verts a detruire
for i in range(len(tmpv)):
if tmpv[i]==True:
print(" a detruire : ",v[i],v[i].co)
adetruire+=[i]
adetruire.sort()
adetruire.reverse()#liste des numeros des verts a detruire rangee dans le sens inverse
for i in adetruire:
bm.verts.remove(v[i])
bpy.ops.object.editmode_toggle()
bpy.ops.object.editmode_toggle()
