Hi!
I have this file. As I see on the GUI the column dont have material. But if I watch it through the API the column have material (the same as the floor).
If I erase the floor (or move it away from the column), the column's material gone too (null reference). Is this a bug or what?
Column material bug?
Hi.
Thank you for your query.
I believe this behaviour is normal.
This is one of those very frequent cases where a good understanding of Revit from a user point of view helps tremendously to work more efficiently with the Revit API.
Revit provides a large number of possibilities to set the material of individual elements, and element material can probably be affected by joining with neighbouring elements:

Here are some discussions in The Building Coder topic group on Element Colour and Material:

You should also always consult the Revit API Developers Guide when exploring a new area, since it provides much more in-depth background information, e.g., in this case, Revit Geometric Elements > Material

I hope this helps.
Best regards,
