I have a problem with the interpretation of surfaces when baking conical tubes: The surfaces are faceted on arrival in REVIT whereas I would like to obtain surfaces in one piece as is the case in Rhino. This then overloads the drawings in REVIT with unnecessary lines. Is it possible toCONICAL SURFACE - RH7 - 21-09-2020.3dm (120.2 KB)
Yes. Similar to this model had problems with the conical ends of the connectors. We will take a look at the specific case.
I made a issue to track on the conical surface. Perhaps you can add your file and comments to that issue too:
I notice that using the Loft function between two circles gives better results than using the revolution function of a rectangle

This is helpful. The current status is that Revit does not like the rational surfaces. Arcs of course are rational. So when doing a revolve by default it creates a rational surface.
Two ways to work around this for now:
- Use the Deformable=Yes option when creating the Revolve. This create a non-rational revolve. That goes across fine.
- As you have already figured out, a Loft also does not create a rational surface and therefore will move across.
We will need to see if there is anything we can do here to somehow convert to non-rational surfaces or if there is another way to convert rationals into Revit. This is the kind of geometry translation are a chasing as we try and determine exact what Revit prefers.
By the way do you use Wormhole to preview the Rhino viewport in the Grasshopper background?
