Meshing
We can technically make our Hello Kitty shirt using the already existing EA t-shirt. But what fun is that?! You are most likely reading this tutorial to learn how to really create custom clothing, and making you own meshes adds an extra kick to your creation!
So now that we've decided which CAS part we are going to clone, it's time to extract some base meshes to build our custom mesh off of. Click Extract Meshes just under the CAS parameters. A window asking where to save your meshes will pop up. Choose whatever destination folder you want to save your work files in and click "Okay". You may close CTU for now.
I highly recommend you make an independent folder for all of your project work files, as CAS creation can get a little messy.
Looking where ever you saved your files, you should now see four new files:
There are three SIMGEOM files and one VPXY file. You can discard the VPXY file as it is not used. The three .simgeom files are the three lod meshes of the shirt.

The word "lod" is an acronym that stands for level of detail. Lod 1 is the highest level of detail, where as lod 3 is the lowest. You will see lod 1 during normal - up close - gameplay. But when you are viewing sims from a distance or the game is still rendering sims, you will most likely see them in lod 2 or lod 3 form.

Multi Lod Meshes
Often times you may see meshes with multiple lod meshes:
Never fear! This just means that the meshes come in parts. Usually lod1_0 is the main mesh and lod1_1 is something silly, like the index finger (dead serious). So you don't have to import both to edit the mesh. However this is a case-by-case thing, so you may or may not have to edit all the lod pieces.
Importing Meshes
Now that we have our meshes, it's time to start the physical meshing using our 3D Modeling program. Remember, you must have the GEOM import/export plugins installed in order to get the meshes into the modeling program. So, take a moment now to verify you have everything installed!
In Milkshape go to File -> Import -> Q Mesh Sims 3 Geom Importer. Navigate to your three mesh files and select the lod 1 mesh. A box saying "Unable to locate bone file. Default skeleton used." will pop up, simply click "Ok".

If you are greeted with...this..don't panic! You just need to adjust the joint size to something more suitable for TS3 meshes. Go to File->Preferences->Misc
Set it anywhere between 0.008 to 0.012 (less or more to your preference). Also, to ease confusion, go ahead and make the skeleton invisible by unchecking the "show skeleton" box on the Joints tab.

Blender users have a slightly different import/export procedure. Please read the instructions provided by the plugin coder or from the Blender website.

Don't add/delete anything
