How to add Hollow clay tiles for constructions

[padisar]

Hi all,

I am working on a project that I need to add Hollow clay tiles/blocks for my external walls. I carefully explored all the system materials in IES-VE database, but unfortunately, I could only find Clay tile. They are not the same obviously and I was wondering if anyone have any suggestions for this ?

As far as I know It is not possible to add/edit system materials, so if the material that you want to use in this case Hollow clay block is not there, what should be done ?

I appreciate any idea and recommendations in this regard.

Many thanks
