Surface as preview

sorry to open a new topic but I cannot find anything in the fourm that helps me. I would like to add some surfaces only as a preview and not as actual data of the document. Is there a way to achive this?

Thanks a lot

Hi Alberto,

I’m not sure about your concrete use case, but did you try to use a Display Conduit?

Maybe that is what you’re looking for…

That could work out. I will try to create a conduit, thanks a lot!

It looks like display conduits are not exactly what I am looking for. I would like to visualize a series of closed curves as if they were stacked surfaces with the technical viewport. I am able to achieve this by adding the surfaces to the model (in a known layer) and switching to technical view, then I remove the layer that hosts the surfaces.

My problem is that I would like to avoid having saving these surfaces but, of course, once they are in the document they will get saved. Any suggestion?

Thanks a lot!

@dale Any idea how to achieve this?

I found out a way, I am hooking a method on RhinoDoc.BeginSaveDocument and removing the layer that contains the surfaces.
