Pipe Joints
This script lets the user create various types of pipe joints.
Usage:
You have to activated the script in the "Add-Ons" tab (user preferences).
The functionality can then be accessed via the
"Add Mesh" -> "Pipe Joints" menu.
Note: Currently only the "Elbow" type supports odd number of vertices.
Version history:
v0.10.5 - createFaces can now create fan/star like faces.
v0.10.4 - Updated the function "createFaces" a bit. No functional changes.
v0.10.3 - Updated store_recall_properties, apply_object_align
and create_mesh_object.
Changed how recall data is stored.
Added 'description'.
v0.10.2 - API change Mathutils -> mathutils (r557)
Fixed wiki url.
v0.10.1 - Use hidden "edit" property for "recall" operator.
v0.10 - Store "recall" properties in the created objects.
Align the geometry to the view if the user preference says so.
v0.9.9 - Changed the script so it can be managed from the "Add-Ons" tab in
the user preferences.
Added dummy "PLUGIN" icon.
v0.9.8 - Fixed some new API stuff.
Mainly we now have the register/unregister functions.
Also the new() function for objects now accepts a mesh object.
Corrected FSF address.
Clean up of tooltips.
v0.9.7 - Use "unit" settings for angles as well.
This also lets me use radiant for all internal values..
v0.9.6 - Use "unit" settings (i.e. none/metric/imperial).
v0.9.5 - Use mesh.from_pydata() for geometry creation.
So we can remove unpack_list and unpack_face_list again.
v0.9.4 - Creating of the pipe now works in mesh edit mode too.
Thanks to ideasman42 (Campbell Barton) for his nice work
on the torus script code :-).
v0.9.3 - Changed to a saner vertex/polygon creation process (previously
my usage of mesh.faces.add could only do quads)

For this I've copied the functions unpack_list and unpack_face_list
from import_scene_obj.py.
Elbow joint actually supports 3 vertices per circle.
Various comments.
Script _should_ now be PEP8 compatible.
v0.9.2 - Converted from tabs to spaces (4 spaces per tab).
v0.9.1 - Converted add_mesh and add_object to their new counterparts
"bpy.data.meshes.new() and "bpy.data.objects.new()"
v0.9 - Converted to 2.5. Made mostly pep8 compatible (exept for tabs and
stuff the check-script didn't catch).
v0.8.5 - Fixed bug in Elbow joint. Same problem as in 0.8.1
v0.8.4 - Fixed bug in Y joint. Same problem as in 0.8.1
v0.8.3 - Fixed bug in N joint. Same problem as in 0.8.1
v0.8.2 - Fixed bug in X (cross) joint. Same problem as in 0.8.1
v0.8.1 - Fixed bug in T joint. Angles greater than 90 deg combined with a
radius != 1 resulted in bad geometry (the radius was not taken into
account when calculating the joint vertices).
v0.8 - Added N-Joint.
Removed all uses of baseJointLocZ. It just clutters the code.
v0.7 - Added cross joint
v0.6 - No visible changes. Lots of internal ones though
(complete redesign of face creation process).
As a bonus the code is a bit easier to read now.
Added a nice&simple little "bridge" function
(createFaces) for these changes.
v0.5.1 - Made it possible to create asymmetric Y joints.
Renamed the 2 Wye Joints to something more fitting and unique.
One is now the Tee joint, the second one remains the Wye joint.
v0.5 - Added real Y joint.
v0.4.3 - Added check for odd vertex numbers. They are not (yet) supported.
v0.4.2 - Added pipe length to the GUI.
v0.4.1 - Removed the unfinished menu entries for now.
v0.4 - Tried to clean up the face creation in addTeeJoint
v0.3 - Code for wye (Y) shape (straight pipe with "branch" for now)
v0.2 - Restructured to allow different types of pipe (joints).
v0.1 - Initial revision.
