developed elevation definition

[monchie]

Hello,

I draw a developed elevation definition to apply wind loads. I noticed that some portion of my walls were blank/no color(red).
Is there any reason for this(please see attached screenshot)?Any help will be greatly appreciated.

Regards,

As far as I know this is an issue with the 3d viewer and won't affect your calculations.
