Description:

A convenient way to transfer data from Blender to a 3DM file. The resulting 3DM file can be opened in Rhino 3D or other CAD packages that supports 3DM file.

System Requirements:

OS: Windows 10 64bit with VC++ runtime 2019 or above.

OS: Mac OSX 11 or above.

OS: Linux 64 with the following dependencies. 

libstdc++.so.6 => /lib/x86_64-linux-gnu/libstdc++.so.6 
libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6
libgcc_s.so.1 => /lib/x86_64-linux-gnu/libgcc_s.so.1
libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6

Installation:

The addon is a ZIP file. Do not unzip the file prior to installation.

Blender version 4.2 and newer:

• Drag and Drop the ZIP file into Blender.

Blender version 4.1 and older:

• Install the downloaded zip file using, Edit->Preferences->Install and choose the downloaded ZIP file. 

Usage:

Select the objects to be exported as a 3DM file and File->Export->Export3DM

The following objects are transferred.

• Mesh objects to SubD or Mesh
• Materials as Meterials
• Collections as Layers

Export3DM export options:

If the objects has SubD modifiers, those will be transfered as Rhino SubD objects. Else the objects will be saved as Rhino Mesh objects.

• Selected Only: Exports only selected objects.(default on)
• Batch mode: Exports each object as a separate 3dm file.(default off)
• Up axis (default Z Up)
• Forward axis (default Y forward)
• Apply Modifiers: Applies all the modifiers before exporting.(default on)
• Disable Booleans: Disables on the boolean modifier. It is very helpful to export the tool objects as separate objects and trimmed in the CAD package. That way, distortions could be minimized and the data can be much lighter (default off)
• 3dm version: Option to save in either v6, v7 or v8  format (default v8)

Limitations:

• There should be only one subdiv modifier and the subdiv modifier should be the last in the stack. The output might not match the shape if there are muliple subdiv modifiers and/or such subdiv modifer is not the last one. In such cases, apply such subdiv modifiers (except the last one) manually.
• Limited support for Blender Materials.
• Limited support for seni-sharp edge creases.
• No support for vertex crease.
