Script won't find face

[davesexcel]

I have this one scripts,

 UI.menu("PlugIns").add_item("Draw Riser") { draw_riser }
 
 
 def draw_riser

prompts = ["length", "Run","height","Rise","Total Rises","Riser Thickness"]
    defaults = [36.0,10.0,1.0,7.75,7,0.5]
    input = UI.inputbox prompts, defaults, "Risers."
        a,b,c,d,e,f=input
        ent = Sketchup.active_model.entities
		#---------Clear All
#Sketchup.active_model.entities.clear!
 #----------------Make 1st Riser
ent.add_line [0,0,d-c+0.1875], [0,0,0]
  ent.add_line [0,-0.5,d-c+0.1875], [0,-0.5,0]
ent.add_line [0,0,0], [0,-0.5,0]
  ent.add_line [0,0,d-c+0.1875], [0,-0.5,d-c+0.1875]
 #edg.find_faces; face=edg.faces[0]
          #face.pushpull a
##group5 = ent.add_group face.all_connected
#----------------Make rest of Risers

ent.add_line [0,b,2*d-c+0.1875], [0,b,d-c]
  ent.add_line [0,-0.5+b,2*d-c+0.1875], [0,-0.5+b,d-c]
ent.add_line [0,b,d-c], [0,-0.5+b,d-c]
  ent.add_line [0,b,2*d-c+0.1875], [0,-0.5+b,2*d-c+0.1875]

# edg.find_faces; face=edg.faces[0]
          #face.pushpull a

#group3 = ent.add_group face.all_connected

#for i in 1..e-2
 # group5 = group4.copy
 # tran = Geom;;Transformation.translation [0, b*i, d*i]
#group5.transform! tran
  #end
 

       
	end
		

Im having issues getting the code to make the faces and then pushpull.

My idea is to make the 1st riser a group on it's own, then make the second riser a group and copy it up.

Thanks

The code for the treads are here.

Do not add the edges to the model entities, they will intersect with the model.

1. Create an empty group, and immediately add a cpoint into it (to keep SU garbage collection from deleting it.)

2. then add the edges to the group's entities collection

3. then do find_faces on the edges inside the group and the face should added to the group's entities.

4. then do the push pull

5. delete the temp cpoint

6. then copy the group

To expand that point...
ent = Sketchup.active_model.entities **group = ent.add_group() ent = group.entities**

Add the two 'BOLD' lines after the ent =
Then everything is inside ' group', which you can 'name' etc as you wish...

Thank you,
That worked.
