Hi,

I am trying to automate this workflow: https://www.youtube.com/watch?v=_bbMv5uXUCM

I am using a script which exports height curves as dwg and orthophoto as jpg from ArcGIS. These two the can be intersected to make a detailed surface with high quality satellite texture on it.

This can be done within SketchUp already, but it is not accurate enough for this purpose.

I have made the first part that gets the image into SketchUp, asks for dimensions and extrudes it, but I am having trouble understanding how to get the FromContoursTool to work.

This is the first part:

# First we pull in the standard API hooks.
require 'sketchup.rb'

# A new menu item is added to SketchUp.
UI.menu("Extensions").add_item("GIS til SketchUp") {
  UI.messagebox("Let's go!") 

# A box asking for the dimensions of the data area.
 results = inputbox(["Length ", "Width; "], ["?", "?"], ["", ""], "Dimensioner på udtræk")

# Width and length are converted to integers.
 length = results[0].to_i
 width = results[1].to_i

# A box asks for an image location. The image is exploded.
 chosen_image = UI.openpanel("Open Image File", "c;/", "Image Files|*.jpg;*.png;||")
 model = Sketchup.active_model 
 image = model.active_entities.add_image(chosen_image, ORIGIN, length, width)
 entities = image.explode

# A face is drawn.
 model = Sketchup.active_model
 entities = model.active_entities
 pts = []
 pts[0] = [0, 0, 0]
 pts[1] = [length, 0, 0]
 pts[2] = [length, width, 0]
 pts[3] = [0, width, 0]

# The face is extruded to a volume.
 face = entities.add_face(pts)
 status = face.pushpull(100, true)
}

This is the second part:

# A new menu item is added to SketchUp.
UI.menu("Extensions").add_item("Contours") {
  UI.messagebox("Let's Go") 

 # First we pull in the standard API hooks.
 require 'sketchup.rb'
 require 'extensions.rb'
 Sketchup;;require 'su_sandbox/GeometryHelpers'
  
 model = Sketchup.active_model # Sketchup active model
  se = model.active_entities # Sketchup Active Entities.  Allows working inside a component.
   ss = model.selection # Model selection, if it exists
    if ss.length == 0 then ss = se end  # otherwise use the whole model. 
 

 # edges = [] # create empty array
 
 # se.each do |e|
  # if e.is_a? Sketchup;;Edge # if e is a sketchup edge
   # edges << e # add to e
    # ss.add e # add e to selection
   # end
  # end
  
 
 Sketchup.active_model.select_tool FromContoursTool
}

Any help would be appreciated - I'm finding it challenging finding documentation on what I'm trying to do. Or if there is a good post already that I have overlooked, please point me in the right direction.

All the best,
Nicholas
