I was looking for a possibility to use Rhino.FileIO.File3dm for reading from (and writing to) a stream, which would be very useful for using Rhino3dmIO in the context of a cloud application (e.g. reading a 3dm fetched from S3). It seems this possibility doesn’t exist. Am I missing sth?

Not currently. I did create static FromByteArray functions for the python and javascript versions of the library. Looks like I need to add this functionality to the .NET version of the library.

That would be fantastic, many thanks for your feedback!

@stevebaer one more question about this: would this also become part of Rhino.FileIO.File3dm in RhinoCommon?

This sounds like something that would be a useful addition to openNURBS too. Or is it already there?

[image] snabela: would this also become part of Rhino.FileIO.File3dm in RhinoCommon? Yes, Rhino3dm for .NET is a subset of RhinoCommon and almost everything added to Rhino3dm will be available in RhinoCommon. I should be able to get this added soon as it is really just more testing than typin…

Found the new FromByteArray(byte[]) in the latest WIP, many thanks. Would it be possible to also support this the other way around, ie a byte[] ToByteArray() or similar?

I just added File3dm.ToByteArray() to V7. This will be available in the next public release of Rhino/RhinoCommon. Thanks, Steve
