Coordinates entered with InputBox

[davesexcel]

Very 1st attempt with Ruby Sketchup, I am trying to have somebody enter 3 numbers in input boxes and then draw the lines to create a rake.
I don't know how to get the numbers entered into the coordinates.
Thanks for any help in this

model = Sketchup.active_model
  entities = model.entities
  prompts = ["Hieght1", "Width","Height2"]
    defaults = [10,20,15]
    input = UI.inputbox prompts, defaults, "Rake Window."

    if input == false 
    UI.messagebox("All Must Be Entered")
    else
    UI.messagebox("Rake has been Drawn, #{input}!")
    end
    #Coordinates from inptut box
  pt1 = [0, 0, 0]
   pt2 = [0, 10, 0]#Height1
   new_face = entities.add_line pt1, pt2
  pt2 = [0, 10, 0]
   pt3 = [20, 15, 0]#Width
   new_face = entities.add_line pt2, pt3
  pt3 = [20, 15, 0]
   pt4 = [20, 0, 0]#Heights
   new_face = entities.add_line  pt3, pt4
  pt4 = [20, 0, 0]
   pt1 = [0, 0, 0]
   new_face = entities.add_line pt1, pt4


Sketchup.send_action("viewFront;")
 Sketchup.send_action("viewTop;")

else
a,b,c=input
UI.messagebox("Rake DATA accepted!, #{input}!")

Then use a, b or c as needed in your points...
So when you have:
pt2 = [0, 10, 0]#Height1
make it
pt2 = [0, b, 0]#Height1

Your input would be logical as XYZ !!!
It's aka RGB...
Although you seem to want to use it as a weird set of ABC v XYZ coordinates...

Thanks, it works

Thanks, with your help I managed to clean it up a bit.
I can draw the face now instead of just drawing the lines.

I am now trying to select the face and offsetting it(Insetting).
I can get the code to select it but it does not inset it.

This is the error I get.
**Error: #<NameError: undefined local variable or methodselection' for main:Object>
C:/Program Files (x86)/SketchUp/SketchUp 2013/Plugins/first.rb:24
(eval):24:in load' (eval):24**

My final outcome will be to have a user input the rake dimensions. It will draw the rake and then draw the offset and move the offset to the right of the original.
Basically, need the original, and then another one 1/4" smaller beside it.

One thing at a time though

This is the code I have so far.
` model = Sketchup.active_model
entities = model.entities
prompts = ["Hieght1", "Width","Height2"]
defaults = [10,20,15]
input = UI.inputbox prompts, defaults, "Rake Window."

if input == false
UI.messagebox("All Must Be Entered")

else
a,b,c=input
UI.messagebox("Rake DATA accepted!, #{input}!")
end
#Coordinates from input box
pt1 = [0, 0, 0]
pt2 = [0, a, 0]
pt3 = [b, c, 0]
pt4 = [b,0,0]
new_face = entities.add_face pt1, pt2, pt3, pt4
Sketchup.send_action("viewFront:")
Sketchup.send_action("viewTop:")
#Select and offset
model = Sketchup.active_model
model.selection.add( model.active_entities.to_a )
newFace = selection[1].offset(-.25)`

Thanks for any replies.

The last line
newFace = selection[1].offset(-.25)
is wrong!
Try
selection=model.selection newFace = selection[1].offset(-0.25)
OR
newFace = model.selection[1].offset(-0.25)

The error is actually quite clear - it is telling you that 'selection' hasn't been defined ...
Note it's best to use 0.25 NOT .25
Also how do you know what selection[1] is going to be ???
The API's offset() method is to offset a point3d by a vector3d + an optional length
BUT there is an offset() method that can be added for faces, edges etc - BUT this is added by another script [by Rick Wilson?], but I don't see you 'requiring' it at the start of your code...

Another tip: your input...
defaults = [10,20,15]
fixes the inputs as integers, if you want the input in inched use decimal numbers:
defaults = [10.0, 20.0, 15.0]
OR
defaults = [10.inch, 20.inch, 15.inch]
