Add appearance

[jostroopers]

I have a family with two extrudes in it.

Paneel and zetwerk.

I would like to assign an appearance to the zetwerk but this fails me.

On the paneel i succeed.

What am I doing wrong or am I missing something.

Select the 'zetwerk' elements and change the Material to By Category so that you can assign the material to the 'zetwerk' subcategory under Object Styles.  It was assigned to the IFC Material.

I assigned some material to the subcategory as an example.  I don't know which ones you want.
