set default pipe size - Where?

[annw2]

I found most of the other default settings for pipes, but I can't seem to find where to set the default pipe size & material to 15" cmp.

Hi annw2-

The material can be selected when adding the part size to the parts list, and the part size is selected when creating the pipe network. Are you looking to have all your pipes default to corrugated metal when added to the parts list?

I am looking to have new networks default to 15" cmp.
