Hi,

I have a module that I wrote that converts mesh vertices into gcode, for CNC work. I'm having difficulty porting this to 2.62.

Code:

from Blender import Mesh, Scene import BPyMesh import numpy as np scn = Scene.GetCurrent() ob = scn.getActiveObject() me = BPyMesh.getMeshFromObject(ob) # gets a mesh from the object with modifiers applied, also so transform wont effect the original mesh data. me.transform(ob.matrixWorld) # transforms the mesh by the loc/size/rot of the object coordinates = [] for v in me.verts:     coordinates.append([v.co.z, v.co.y])

I've tried this but I need to get the global coords, not the local ones:

Code:

import bpy myobj = bly.context.object.data coordinates = [] for v in me.vertices:     coordinates.append([v.co.z, v.co.y])

what is the equiv. to:
me = BPyMesh.getMeshFromObject(ob)
me.transform(ob.matrixWorld)

Thanks much.

Hello,

I'm a very recent Blender script learner...

From my knowledge:

# World coordinates:
world_v = v.co * ob.matrix_world

as for the last question:
me.transform(ob.matrix_world)

you better port it to 2.63 (bmesh) if you plan to update Blender periodically...

with modifiers applied:

Code:

import bpy ob = bpy.context.object me = ob.to_mesh(bpy.context.scene, True, 'PREVIEW') # or 'RENDER' me.transform(ob.matrix_world) coordinates = [] for v in me.vertices:     coordinates.append([v.co.z, v.co.y])     # to_mesh() creates a new mesh, should remove it if not needed afterwards bpy.data.meshes.remove(me)
