Introduction

This grasshopper scripts automates the design and drawing production of a singular working platform. It consumes a surface model and polygon and auto-generates a working platform design. The user has a number of user defined parameters available to further refine the design and drawing annotations. A python script is then run to generate a GA Plan and Section drawing which can be exported as PDF. The entire file can then be saved as a .dwg for import into other design software

This repository (repo) contains:

  • A Rhino file that includes the required drawing templates.
  • A Grasshopper file which automates the design and drawing production of a working platform.
  • A Python file that is used for drawing automation.
  • A CSV file that contains the format to upload SOP coordinates.
  • A dependencies folder with the required plugins needed to run the software.
  • A media folder containing screenshots of the tool in use.
  • A license file
  • A README file

Dependencies

For the Grasshopper script, you will need the following dependencies (these are all included in dependencies folder):

packageName, version, Link to webstore (e.g. Food4Rhino)

If a dependency is missing grasshopper will flag this up as a missing pacakge. If this is the case please get in contact so this can be rectified.

Inputs

Required input files and geometry

  • Site terrain / topography file (.dwg / .dgn)
  • Platform edge polygon
    • Manually drawn closed polygon
    • CSV file input with SOP coordinates using file in repo with correct data format (.csv)

Process

Through a series of user input parameters the working platform is generated in real time and outputs drawings and a CAD file. See the user guide for more information. This process is handled by the grasshopper script in the background, made accessible by the UI and is displayed in the Rhino model window.

Outputs

  • 1 x GA Plan drawing (.pdf)
  • 1 x Section drawing (.pdf)
  • 1 x CAD file for import into other software (.dwg)

All slider inputs can be used by dragging the handle or double clicking and entering your parameter value.

0.0 | Set Up

0.1 | Initial Launch of Rhino 7 & Grasshopper

  • Launch Rhino 7
  • Once open you will have 4 viewports open in the Rhino Window.
  • In the Rhino Command Line on the top ribbon type 
    Grasshopper
    and press Enter
  • A new window will open, this is the Grasshopper Window

0.2 | Install Dependency Files

  • In the top left of the Grasshopper Window press File -> Special Folders -> Components Folder
  • In this Components Folder drag and drop the contents of the Dependies Folder found in the workingPlatforms folder you previously downloaded.
  • Once you have copied across the files and folders inside Dependencies Folder close both Grasshopper Window and Rhino Window.

0.3 | Open The Working Platforms Tool

  • Launch Rhino 7
  • Once open you will have 4 viewports open in the Rhino Window.
  • In the top left of the Rhino Window press File -> Open and open AWP_Automated _Piling _Platforms.3dm from the workingPlatforms folder
  • In the Rhino Command Line on the top ribbon type 
    Grasshopper
    and press Enter
  • In the top left of the Grasshopper Window press File -> Open and open AWP_Automated _Piling _Platforms.gh from the workingPlatforms folder
  • This will open up a User Interface Dialogue Box which is how the Working Platform Tool is run.

Further Development

List Potential Further Developments (Planned & Potential) To further improve the script, the following has been considered (but not at all tested) for the Proof of Concept. The followin should be included if funding is acquired:

  • Integration with Tekla Tedds to run engineering calculations and provide calc sheet as an output for engineering checks
  • Feedback engineering calc checks to user interface
  • Calc sheet to inform platform thickness
  • Load table to be included in drawing sheets
  • Fall annotation
  • Access ramp annotation
  • Multiple polygons for multiple platforms
  • Piling rig / equipment shown in drawing
  • SOP annotation in section

Known Issues

  • Only one section can be created per design
  • Only one polygon can be used at a time
  • Auto scaling of text annotation isnt 100% accurate
