Hi everyone, If you use RhinoDoc.ActiveDoc in the .Net environment there is a BIG Warning that I better don’t use it, because of MAC compatibility. So far I was pretty much ignoring it (Nobody working with a Mac Version at our office anyway). However –when writing code from now on I think it woul…

In Rhino for Mac you can have multiple documents open at the same time. When the user switches document during a command, the ActiveDoc will change. ActiveDocAtCommandStart is already given in the command function signature RunCommand(RhinoDoc doc, RunMode mode) the doc parameter is the active one …

Thank you, the “problem” is that I don’t want to pass the “doc” given in the command down to all my functions. If I create a function called “AddLayer” I would have to pass something like "AddLayer(string layerName, RhinoDoc doc)" It would be much nicer not to have to do that and I would be able …

Yes, passing the doc reference directly or as part of a “Settings” class is the way I do this. I don’t find this to be too much hassle to be honest. Also it adheres to the principle of dependency injection where it is clear in a function signature what external dependencies it has.

I concur with Menno. It’s not that big a deal to add a doc argument to functions that modify a document. If you find yourself passing several things to all functions (say, a RhinoDoc, a DisplayPipeline and a Viewport) you can wrap them up in a small context class that gets passed around instead.

Well , I guess that makes sense then. Didn’t think of dependency injection. Good to know how you would approach it. Thanks Martin

So the easiest way to do this is make a public variable (rhinoDoc) that will update when a Command is Triggered? This way it will update from different doc’s?

Oke so a direct “link” like: Private Function MyFunction (byval doc as RhinoDoc) `todo End Function

Indeed. If you put your logic in a separate class, then you can use a class level variable as well: Public Class MyFunctionality Private Readonly _document As RhinoDoc Public Sub New(doc As RhinoDoc) _document = doc End Sub Public Function MyFunction() As SomethingOrOther _docume…

a bit off topic but i’ve tried something similar just to see what happens… (start drawing a curve in one document then finish in another.)
it just cancels the command in doc1 and switches focus to doc2.
