I am relatively new to Speckle. I am trying to test Rhino (7) - AutoCAD (2022) data exchange. Main aim is to get a CAD drawing into Rhino for further operations in gh and if possible send back to CAD post gh operations. I tried to stream some curves and lines. It works fine as far as geometry is concerned but I have a few queries.
Firstly, the CAD line properties are important for me (colour, thickness, style, layer, etc.). When I receive back in rhino I only get simple white lines. The colour, thickness, line style are all missing. Is that expected?
I tried to create some lines in Rhino and put them on different layers with layer colors and line style. Tried to receive them in AutoCAD but faced the same issue. Only layer name is imported that too with an extended name.
Can someone please guide me how I can transfer complete line data, if it is possible. I really hope I am missing something. Any tutorials for something similar would be greatly appreciated. Is grasshopper having any special components to do that?
Secondly, if I import the lines in rhino (created in autocad), rotate them or scale them in rhino and send them back to cad, it will create a new copy of the lines. I was hoping that it would replace the existing geometry in cad. Similarly if I perform operations on rhino lines received in cad and send them back to rhino, it would create a new copy instead of replacing the old lines. Is it possible to update existing geometry? Could be as simple as replacing all the geometry in the given layer.
Thank you very much.
