Step-1:
Create a Rhino file with stopes named as objects:
- (Import ‘Example-Input’)
- Note: it doesn’t matter what layer they are in.
Step-2:
Create a material library (mtl) with the colours that you want to use (the example I have done has 5 colours for ELOS). An mtl file is created as a separate file when an OBJ as exported.
Step-3:
Export the required shapes as obj with the following settings: Note: No ‘groups’ should be added into the obj file upon export Note: The mtl file will be created at the save location when the obj is created.
Step-4:
Generate an excel sheet which has the columns:
Stope names Mining sequence Material Code that you want the stope to be
Note: In the example I have put a ‘+’ at the end of the mining sequence, as this allows a cumulative sequence to be viewed when doing a layerbook in Rhino
Step-5:
Modify paths/file names in python script (update_obj_codes) and run The files paths to modify are lines 32 to 35 in the python script.
Step-6:
Run the Python script in the command prompt (Ensure you are using Python Version 3.9.7). Start by opening the command prompt. Type ‘cd’ followed by a space and then paste in the location of the python script and press enter. On the second lime type ‘python’ followed by a space and paste the script name including the ‘.py’ file type before pressing enter. The script will then run creating the required output files.
Step-7:
Drag the obj that has been generated into Rhino, using the following settings:
Step-8:
Bingo, they have been put into layers and coloured according to your material library
