Name: TIG-Superdrape.rb
###
When initially installed this tool is an 'inactive' Extension;
you must 'activate' it the once by checking:
Preferences > Extensions > Super Drape
[Note: it can be 'deactivated' later by unchecking its Extension and
then restarting Sketchup]
###
Usage:
Menu > 'Tools' > 'Super Drape'
OR
Menu > View > Toolbar > 'Super Drape' [initially deactivated]
###
This tool drapes one group onto another group - much like the
Sandbox Drape tool [BUT much more consistently] AND it also copies
materials from with the 1st group to the 2nd group.
Activate the tool.
You are prompted to select the group to drape, and then the 2nd group to
drape onto.
It is one step undoable.
###
Tips:
The draped group must be above the 2nd group, but placing it very far above
it might result in some inaccuracies.
The two groups should consist of one set of faces, oriented 'up'.
The lowest face is the draped group will supply the materials if there are
'layers' of faces that overlap.
The highest face will receive the drape if there are 'layers' of faces that
overlap; to be on the safe side it's recommended you use single 'layers'
of non-overlapping faces in the groups.
Any face < ~1mm will probably be ignored when materials are assigned.
Faces may be angled from the horizontal in both groups - inside a group
or even a group itself.
Any textured materials in the draped group will have their UVs correctly
transposed in the materials used in the 2nd group, but they might be
foreshortened unexpectedly if a draped group face slopes significantly
more than the equivalent face in the 2nd group.
Any processed groups with more than one instance will be made unique first.

Version:
1.0 20111004 First issue.
1.1 20111005 Face 'pairing' more robust. Only uppermost face gets draped.
1.2 20111006 Trapped 'group.material'. Robust Intersecting/overlap-trimming.
1.3 20111006 Group.copy now recast to avoid rogue scripts messing it up.
Multi-level faces in the draped group are now allowed.
1.4 20111008 1st group temporarily moved nearer to 2nd to minimize errors.
Original is unaffected by group.material >> default faces.
1.5 20111010 Adjusted to minimize missed facets etc.
1.6 20111021 Intersecting of meshes improved etc.
1.7 20111028 More robust intersecting method.
1.8 20111028 Typo in code fixed!
1.9 20111028 Already erased edge error trapped.
2.0 20111103 More robust intersecting methods accelerated.
3.0 20111204 Made into an Extension with own loader etc.
3.1 20111204 Glitch with toolbar button/icons resolved.
