      I am trying to figure out this loop,
      when i=e then I want b=0.5

      Thanks,
      Dave

      
      UI.menu("PlugIns").add_item("Draw stairs") { draw_stairs }
      
      def draw_stairs
      
      prompts = ["length", "Run","height","Rise","Total Rises"]
          defaults = [36.0,10.0,1.0,7.75,7]
          input = UI.inputbox prompts, defaults, "Tread."
      
      
          if input == false
          UI.messagebox("All Must Be Entered")
          else
            a,b,c,d,e=input
          #UI.messagebox("Tread input accepted!, #{input}!")
          end
      
      
          ent = Sketchup.active_model.entities
      for i in 0..e-1
      [b]#if i=e-1 then b=0.5[/b]
           
        ent.add_line [0,(b+1)+i*b,0+i*d-1],[0,(1.5+i*b),0+i*d-1]
        ent.add_line [0,1.5+i*b,0+i*d-1],[0,1.5+i*b,-d+(i*d)-1]
       ent.add_line [0,1+i*b,0+i*d-1],[0,1+i*b,-d+(i*d)-1]
      ent.add_line [0,1+i*b,-d+(i*d)-1],[0,1.5+i*b,-d+(i*d)-1]
        ent.add_line [0,1+i*b,-1+i*d],[0,0.5+i*b,-1+i*d]
        ent.add_arc [0,0.5+i*b,-c/2.0+(i*d)],[0,0,-1],[-1,0,0],c/2.0,0,180.degrees,20
          ent.add_line [0,0.5+i*b,0+i*d],[0,b+(i*b)+1,0+i*d]
          edg=ent.add_line [0,b+1+i*b,-c+i*d],[0,b+1+i*b,0+i*d]
           edg.find_faces; face=edg.faces[0]
         
          # #face = ent.add_face [0,0,0], [a,0,0], [a,b,0], [0,b,0]
          #face.reverse!
           face.pushpull -a
         
      	# edg.soft="true"
      	 #group1 = ent.add_group face.all_connected
          end   
            #group1_copy = group1.parent.entities.add_instance(group1.entities.parent, group.transformation)
      end

        Did you mean when i=e? Because i is never going to equal d(rise).

        Nothing is worthless, it can always be used as a bad example.

          Yep, you are correct,
          I wonder if it might be easier to find the back face and pushpull it e-(e-0.5)
          How do you pushpull the back face only?

            I'm not sure which one is the "back" face is but you just need face criteria that only matches the one of interest. Like in the case of the edges to be softened, they had to be of length "a".

            By the way, e-(e-0.5) = 0.5.

            Nothing is worthless, it can always be used as a bad example.

              Oh ya, I guess it would be e-0.5 so it would have to be pushpulled -(e-0.5)

              I keep getting pushpull stuck in the head.

              What I am looking for is on the last loop make b=0.5

              Thanks

              I have tried adding k into the mix mix with no success, now b is 0.5 on all the loops.

                Alright I can get the b=0.5 on the last loop but can't get it to the correct location, because I changed b to 0.5 !!!.

                    prompts = ["length", "Run","height","Rise","Total Rises"]
                    defaults = [36.0,10.0,1.0,7.75,7]
                    input = UI.inputbox prompts, defaults, "Tread."
                    
                        a,b,c,d,e=input
                
                        k = 0 #<<--- start k=0
                        ent = Sketchup.active_model.entities
                        for i in 0..e-1
                        if k>e-2 then #<<<----if k=e-1
                        b = 0.5
                        end#<<<---
                		k=k+1
                        ent.add_line [0,(b+1)+i*b,0+i*d-1], [0,(1.5+i*b),0+i*d-1]  
                        ent.add_line [0,1.5+i*b,0+i*d-1], [0,1.5+i*b,-d+(i*d)-1]

                        edg=ent.add_line [0,b+1+i*b,-c+i*d],[0,b+1+i*b,0+i*d]
                        edg.find_faces; face=edg.faces[0]

                  Two things.

                  The if k=e-1 failed because the proper syntax is if k==e-1.

                  Because you use a multiple of b to define the location, changing it for the last one requires a different formula. Shorten the For loop to e-2 and copy and modify the code in the loop to create the last step with b=0.5.

                  Nothing is worthless, it can always be used as a bad example.

                    Excellent, thanks for the suggestion...it worked.

                    Just a side note, is there a "clear All" code that can run at the beginning of this code?
                    for example

                    ` clear_all#< clears everything on the screen.

                    prompts = ["length", "width","height","Rise"]
                    defaults = [36.0,10.0,1.0,7.75]
                    input = UI.inputbox prompts, defaults, "Tread."

                    if input == false
                    UI.messagebox("All Must Be Entered")
                    else
                    a,b,c=input
                    #UI.messagebox("Tread input accepted!, #{input}!")
                    end
                    
                    ent = Sketchup.active_model.entities
                    ent.add_line [0,b-c/2,0],[0,0,0]
                    ent.add_arc [0,0,c/2.0],[0,0,-1],[-1,0,0],c/2.0,0,180.degrees,20
                    ent.add_line [0,0,c],[0,b-c/2,c]
                    edg=ent.add_line [0,b-c/2,c],[0,b-c/2,0]
                    edg.find_faces; face=edg.faces[0]
                    #face = ent.add_face [0,0,0], [a,0,0], [a,b,0], [0,b,0]
                    #face.reverse!
                    face.pushpull -a`

                      One idea is starting using groups to organize your geometry.
                      Clearing everything on the screen, sounds like a dangerous approach to me.
                      Just a simple tip..

                      ents = Sketchup.active_model.entities
                      gp = ents.add_group
                      ent = gp.entities

                        In SU2014 and up: just type cls

                          Thanks,
                          I'm just trying to find a way not to have to keep pressing 'Ctrl & "A" then delete, every time I want to test a code.

                            for testingyour code you can use

                            Sketchup.active_model.entities.clear!
                            

                            but have another look at TT's notes and the API at wrapping your code in a Start Operation...
                            then use your Undo shortcut...

                            learn from the mistakes of others, you may not live long enough to make them all yourself...

                                Ah, right! Understood.

                                Well TT and Driven got the answers already.
