Tube coping template wrappers

Iceracer

This is exactly what Im looking for. If there is no plug in for it I would give a go at making one if there is a tutorial on making plugins.

Once you do the intersect faces routine, you can use Jim Foltz's Unfold plugin to lay the wrapper out flat. Or as Ken did, use the Flattery plugin.

Ok I just looked at some ruby stuff way over my head....

what the intersect faces routine?

It's a basic native thing to intersect faces. Select the surface of the wrapper, right click on it and choose Intersect Faces>With Model to create the intersection. Make the pipe a component or group first so it doesn't get modified during the intersection process.

Tube Coping.gif
Here is a quick and dirty Plugin that duplicates Ken's process.

def tube_coping

mod = Sketchup.active_model
ent = mod.active_entities
sel = mod.selection
vue = mod.active_view
@vtd ||= 6; @htd ||= 4
val = UI.inputbox(["V Tube Dia;","H Tube Dia;"],[@vtd,@htd],"Tube Coping")
if val
 @vtd,@htd = val; grp = ent.add_group; gent = grp.entities
 cir = gent.add_circle(ORIGIN,Z_AXIS,@vtd/2,360)
 fac = gent.add_face cir
 fac.pushpull -@htd*2
 opt = ORIGIN.offset(X_AXIS,@vtd).offset(Z_AXIS,@htd)
 htc = gent.add_circle(opt,X_AXIS,@htd/2,36)
 vts = htc[0].curve.vertices.map{|v|v.position}
 hpt = []; del = Math;;PI*@htd/36
 #vts << vts[0]
 vts.each{|v| hpt << mod.raytest([v,X_AXIS.reverse])[0]}
 opt = ORIGIN.offset(X_AXIS,@vtd*2).offset(Z_AXIS,@htd/2);lpt=opt.clone
 cpt = []; cpt << opt
 for i in 0...vts.length
  npt = lpt.offset(Z_AXIS,vts[i].distance(hpt[i]))
  cpt << npt; lpt.offset!(X_AXIS,del) if i<vts.length-1
 end
 cpt << lpt
 ent.add_face cpt
 grp.erase!
end

end

Darn sdmitch your quick on the draw.

One problem with your plugin, I show a 90 angle just to simplify the drawing. However, the angle can be any reasonable angle.

So if you add an input for the angle it should be good to go.

Thanks

How is the angle measured? From vertical? What should the min and max angle be?

Iceracer

The angle should be calculated from a existing centerline in two steps possibly 1 -3 tubes intersecting then select the tube we want to cope to the node.
Sdmitch are you in the US?

Yes I am.

Please post a sample model,version <= 2014, to play with.

Please describe just how you would envision how the plugin should work and make it "Coping for Dummy's"

Iceracer

Ill have to get it Tommoro I can snap a picture of the actual piece and send you a file tommoro if you need it. And I appreciate the coping for dummies. This is way out of my expertise.

Iceracer

Here is my dilema coping a single angle is not a issue but adding multiple tubes and then rotating and angling back makes it difficult and then coming in on the other end of the tube make it more interesting.
Mitch apparently I cant add a skp file here for you. send me a pm with a email and Ill send the joint to you so you can see it more clearly with all the angles happening.
