Ruby scripting issues

[nransome]

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

The code is:
Sketchup::active_model.select_tool(FromContoursTool.new())
since it's a Tool and therefore needs a .new() to initialize it...

# First we pull in the standard API hooks. require 'sketchup.rb' require 'extensions.rb' Sketchup::require 'su_sandbox/GeometryHelpers'

(1) They do not really "pull in the API hooks".

(2) You only require scripts and libraries, if this script (which has the require statements,) are going to use what is defined in them.

And your script uses nothing in those two files. (The files are located in the "Tools" sub-directory, of SketchUp program directory. They are not scrambled and can be read. Also everything defined in the "extensions.rb" file, is explained in the API dictionary under the SketchupExtensions class.)

(3) require statements are always best located at the top of a file, since they should be dependencies. If they cannot be loaded, the rest of the script should not be run, because a LoadError exception will be raised.
