How to get the colour of an object within a vb module

Hello,

I've been trying to get the colour value of an object from a vb module but I cant seem to manage. The objects have been colour coded through another program so I want to use the colour value as a way to reorganize the list's hierarchies (blue has less value than red...).
If I plug the list directly into the colour button it returns false rgb values so that doesn't work either.
Any thoughts?

Thanks

M

Hi Mateo,

sorry for the late response. You can get object attribute information from Rhino provided you have an Object ID.

You should be able to get the ID of any referenced object. Just plug the Object data into a GUID parameter, then use the following script:

You're using the new SDK (RhinoCommon) whereas the example I posted way back then used the old SDK (Rhino_DotNET). Functions, classes and properties have all changed. I attached a file with updated code, but this is what it looks like:

Dim obj As Rhino.DocObjects.RhinoObject = doc.Objects.Find(id)
If (obj Is Nothing) Then
col = Color.Transparent
Else
col = obj.Attributes.ObjectColor
End If
