How to change an extrusion material?

[chthum]

Hi,

Does anyone know how to change an extrusion material to compound ceiling?

I have created two arrays group. The first array consists of compound ceiling and the second array is an extrusion object. The purpose is to run solar analysis and get the cumulative insolation on the ground. The compound ceiling array is able to reflect cumulative insolation on the ground but not on the extrusion object. The difference between the two arrays are material and also angle of panel.  Please refer to attached PDF and Revit files for details.

Thank you.

Are you asking if grouped elements can have different materials between instances of that group?  No.  

BTW: Nesting of Model Groups is not advisable.  FWIW: https://knowledge.autodesk.com/support/revit-products/learn-explore/caas/CloudHelp/cloudhelp/2016/EN...

Holy groups within groups within groups Batman!!

Long story short....edit your panel, select the extrusion, associate the element to your PV parameter by clicking the little box at the end of the material row.

Hi @barthbradley and @Anonymous,

Thank you for your comment. I would like to have same material between instances of the grouped element. If nesting model group is not advisable, what would your suggestion to create many rows of PV panels and run solar analysis in Revit? In this case, my purpose is to get solar insolation on the ground floor not on the surface of PV panel. 

I watch the video from Autodesk University titled "How much is Zero? Integrating Solar Power Design and Energy Analysis" from below link. 

https://www.autodesk.com/autodesk-university/class/How-Much-Zero-Integrating-Solar-Power-Design-and-Energy-Analysis-2015?_ga=2.35487969.1168964303.1558680018-359705699.1555624339#downloads

I used the PanelRefSurface.rfa file (extrusion object) downloaded from the above link as my PV panel to run Solar Analysis. However, when I comparing the analysis done using compound ceiling as PV panel material, the result is totally difference (refer to my previous PDF file, difference in colour). 

I followed @Anonymous suggestion to click the little box at the end of the material row and selected Default Wall as material (refer to attached Default Wall). But, this Default Wall material doesn't work as Compound Ceiling material when running solar analysis. Again, my purpose is to get cumulative insolation on the ground not on the PV panel. So, I need a material that can acts as shade to reduce insolation on the ground. Any idea on the suitable material for PV panel? 

Looking forward to hearing from you. Thank you.
