The Dominion

A Grasshopper plugin for modelling conics and mathematical curves accurately from equations.

Getting Started

If you are only interested in using the plugin, follow the Run instructions.

Prerequisites

• Rhino 6 or Rhino 7

Run

Run the sample files once loaded located in the samples folder.s

Option 1 (Experimental):

1. Install the plugin from the Yak Package Manager

Option 2:

1. Download the latest version from food4Rhino.
2. Copy all unzipped contents into your component library, usually C:\Users\($user)\AppData\Roaming\Grasshopper\Libraries
3. Unblock all files

Option 3:

1. Navigate to Releases
2. Download and unzip the latest Release, e.g. the_dominion_x.x.x.x.zip.
3. copy all unzipped contents into your component library, usually C:\Users\($user)\AppData\Roaming\Grasshopper\Libraries
4. Unblock all files

Build

Steps

If you want to build the application from source code on your local machine, follow the steps below:

1. Clone the repository.
2. Restore the NuGet packages in Visual Studio.
3. Build the Application.
4. Open Rhino.
5. Run _GrasshopperDeveloperSettings from the Rhino Command Line.
6. Add a Folder in the developer settings window, and point the explorer to the 'bin' folder of 'the_Dominion' clone on your local machine, e.g. C:\Users\($user)\source\repos\bulgos\the_Dominion\src\bin
7. Run _Grasshopper from the Rhino Command Line and navigate to the 'Dominion' tab.

Deploy

If you are an owner and want to deploy the application to Yak:

Build Yak packages with Rhino 7
1. Set Visual Studio Build Configuration to Release.
2. Build Application (this will populate the \dist directory when building Release Configuration).
3. Open command prompt and point at root of the repository.
4. Navigate into distribution directory cd \the_Dominion\dist
5. Spec the manifest .yml file "C:\Program Files\Rhino 7\System\Yak.exe" spec
6. Update the manifest manually if necessary.
7. Build the package (currently windows only) "C:\Program Files\Rhino 7\System\Yak.exe" build --platform win

1. Build the Application with the steps described above in Build.
2. The Release configuration automatically specs a manifest file and builds the application (if the yak package manager/Rhino 7 is installed)
3. If manual edit of manifest file not required, skip to 7.
4. Update the manifest manually if necessary.
5. Build the package (currently windows only) "C:\Program Files\Rhino 7\System\Yak.exe" build --platform win

Push package to Yak server

7. Login to Mcneel account "C:\Program Files\Rhino 7\System\Yak.exe" login
8. Push package to server "C:\Program Files\Rhino 7\System\Yak.exe" push the-dominion-x.x.x-any-win.yak
9. Check package has been successfully pushed "C:\Program Files\Rhino 7\System\Yak.exe" search --all --prerelease the-dominion

If it is your first time deploying, try the test server:

8. Push package to test server "C:\Program Files\Rhino 7\System\Yak.exe" push --source https://test.yak.rhino3d.com the-dominion-x.x.x-any-win.yak

9. Check package has been successfully pushed "C:\Program Files\Rhino 7\System\Yak.exe" search --source https://test.yak.rhino3d.com --all --prerelease the-dominion

10. Upload the_dominion.XX.tar archives to food4Rhino.
