Blender Primstar Empty Mesh Missing

Does anyone have any clues as to why I cannot get the Add Empty Mesh Option in Blender? It’s driving me bonkers! I have all the other Primstar options but Empty Mesh is simply NOT there. Yes :) I am in object mode. If I put blenders file path to just Primstar I get Add> Mesh> (python icons)> Sculpt Mesh , Torus. When I change the path to the JASS scripts I get Add> Mesh (python icons) >Jass Lib Scripts, Sculpt Mesh, Torus.
I have reinstalled Blender. Did not help. I’m using Blender 2.49b and Python 2.6.2. that came with the install Blender package. If the python paths are not right how do I reinstall Python or check it? Am I correct that Empty Mesh originates from Primstar? Or does it originate from Python? Cannot wait to get all the Tech issues straightened out. Thank You, Thank You for any help you may have.

You can make empty meshes without any scripts. Just add a plane (or any other type of mesh) from the menu, switch to edit mode, press X and select "all". This will delete all the vertices, and the result will be an empty mesh. It's so simple, I wonder why anyone would write a script for that.

The Empty Mesh script comes with blender. Here is its content:

From: someone

#!BPY
"""
Name: 'Empty mesh'
Blender: 243
Group: 'AddMesh'
"""
import BPyAddMesh
import Blender

def main():
BPyAddMesh.add_mesh_simple('EmptyMesh', [], [], [])

main()


You should find it in the blender default scripts directory. It is named "add_mesh_empty.py" I have no idea why it is not available in your installation.

@Masami: I think this script is a convenience function which allows to create an empty mesh without first creating something and then remove it again ;-) I only wonder why it has been implemented as script and not embedded into the blender code . Maybe a historical thing ?

Another guess: This sounds like you never have installed a full python 2.6.2 ? You just rely on what comes with blender ? If this is so, then you must install a full python (2.6.4 will be what you want). Then get back to blender. And maybe then you can see the "empty Mesh" button. There is no need to reinstall blender after you have installed python.

The OP seems to think empty mesh is a primstar feature.. it's not. With or without Primstar installed... from Object Mode... in 3D view... Spacebar...add...mesh...empty mesh.

I guess the coders left it out for convenience. :P

The problem I see with convenience functions like this is that people depend so much on them and get lost when the functions are missing or stop working. Scripts make sense when they automate boring and repetitive tasks, but some scripts seem to be designed with the intention to keep people from understanding how things work.

Take Primstar for example. Is it a time saver? I don't think so. Does it keep people from understanding how sculpt maps work? Absolutely. All the recurring LOD-related questions seem to come from people who use Primstar and similar scripts. Obviously they would be lost without those scripts because they don't really understand what the scripts do.

Thank you all Masami, Gaia, Johan, so much for your help. I’m a graphic artist, old school, struggling with technology. Instead of burying myself in the painting studio in college, I should have been over in the computer lab! Your right Masami I’m clueless on understanding how the scripts work. Bit by byte I’ll get there. Now I need to figure out how to get the full python install. I downloaded the newer version, but cannot figure out how to update the Python that is allready in blender. I tried a few things like just putting the new unzipped python folder in the blender folder. Did not update. Thanks again all, I appreciate all your time and help, would be lost without it.
