Implement the SpeckleDynamoConverter

[teocomi]

https://github.com/speckleworks/SpeckleDynamo/blob/master/SpeckleDynamoConverter/SpeckleDynamoConverter.cs

Status

Primitives

• Numbers
• Boolean
• String
• Null
• Point
• Vector
• Plane

Linear

• Line
• Polygon
• Rectangle
• Polyline (Dynamo PolyCurve with all its curves straigth)

Curves

• Circle
• Arc (still buggy due some differences with Rhino)
• Ellipse
• EllipseArc (only ToSpeckle() as NurbsCurve)
• Curve
• PolyCurve
• NurbsCurve
• Helix (only ToSpeckle() as NurbsCurve)

Other Geometries

• Mesh
• Solids
• Brep (SpeckleBrep needs a more defined structure)
• Box (can be converted as Cuboid?)
• Extrusion (same as Brep)

Without Dynamo counterpart (?)

• Interval
• Annotation
• ArchivableDictionary/ Dictionary

[didimitrie]

For reference, Archivable dictionaries and such got a little bump/update to their serialisation part to normal dictionaries in speckle rhino. Nothing major, just a heads up!

Also some serialisation routines changed recently (PR is still awaiting approval).

The stuff is here: https://github.com/speckleworks/SpeckleRhino/blob/Dim/dev-fix-wierd-curves/SpeckleRhinoConverter/src/SpeckleRhGhConverter.cs

Some recent changes in core that might come of handy: ~all SpeckleObjects now have a GenerateHash() method that you can call outside of the constructor, and that takes care of setting up the hashes (geometry & geometry+properties).

This can be nicely used if you set object fields outside the constructor.

@teocomi this might help: https://github.com/ksobon/MantisShrimp/blob/master/Grasshopper/mantisshrimp.py

I did most of the conversions from Rhino>Dynamo there, so it would give you a leg up on this stuff. Also @archinate did a similar thing here: https://bitbucket.org/caseinc/rhynamo/src

Actually his might even be better since it's already in C#.

I've updated @teocomi's main thread to reflect the current status of SpeckleDynamoConverter.

All but brep/surface based geometries are implemented now. Closing this issue.
