I've edited tree models which I think look good yet remain low-poly in 2D plan, as a realistic "2D cutout" and as 3D polygons. (Using nested 3D symbols on different classes within "3D graphics") The 2D cutout mode looks great in Lumion/rendering/section but not in IFC export since alpha mask are disabled. Therefore I've added a 3D low poly version of each tree on a separate class. This works great in VW/Lumion. However, when I export to IFC every object within "3D graphics" is visible, including those on tags that are turned off. I've also tried classifying these objects as different level of detail, but this doesn't seem to affect IFC export. Furthermore, the entire tree object turns green, ignoring the colors I've assigned inside "3D graphics" editing. How can I hide parts of an model when exporting to IFC? (and preferably maintain assigned fill in VW) Thank you!

Thank you for your reply! Not sure if I understand. The trees are categorised as "plants", and if I edit the 3D graphics the object I encounter is a "3D symbol", with the trunk a bit below insertion point. Yet if I send it to terrain it will send the lowest point to terrain, not insertion point.

I've created a series of tree objects that I find look good in 2D, 3D/section, Lumion rendering and IFC export. However, when I send them to the surface, they automatically land with the lowest part of the model/trunk on the terrain, instead of the object base/origin. This means I have to set the height to -0.5 m afterwards (especially where the terrain is not flat). Is there any way to change this? I'd like the component base to land on site model, not the root.
