Dustin's Fifth Tutorial

I think these might not work perfectly with the newer Pyprp versions, but they're here for posterity :P

Introduction

This is a great way to help you model solid objects. It only applies to objects like cubes, spheres, the "monkey's head", cylinders, and other "solid" objects. It doesn't apply to grids, planes, tubes, circles, and other "surfaces".

Joining 2 objects together into 1

1. Move the 2 objects together, so that they overlap in the way you want.
2. In object mode, select the first object.
3. Hold down "shift" and select the second object.
4. Go to Mesh->BooleanOperation->Union
5. You now have 3 objects: the 2 originals and your new object!
6. You will have to move them around, and delete the originals if you want.

Getting the region that is shared between 2 objects

1. Move the 2 objects together, so that they overlap in the way you want.
2. In object mode, select the first object.
3. Hold down "shift" and select the second object.
4. Go to Mesh->BooleanOperation->Intersection
5. You now have 3 objects: the 2 originals and your new object!
6. You will have to move them around, and delete the originals if you want.

Cutting part of an object out with another object

1. Move the 2 objects together, so that they overlap in the way you want.
2. In object mode, select the object that you want the part cut out of.
3. Hold down "shift" and select the object that you want to use to cut with.
4. Go to Mesh->BooleanOperation->Difference
5. You now have 3 objects: the 2 originals and your new object!
6. You will have to move them around, and delete the originals if you want.

Other things you can do

So now you have another solid object, that you got by using one of the above 3 methods. You can use it just like any other solid object, including using again in one of the above methods! Also: you can now make holes in the object, by selecting some vertices and deleting them, or by using this tutorial: http://alcugs.almlys.org/Openings
