I would like to find a block that would insert all the layers needed per:US National Cad Standard orAIA Layering Standard or Public Works & Government Services Canada Drafting standardCreating all the layers required for Fire suppression, HVAC and Plumbing for one's own use would require a lot of time. Would greatly appreciate any help. Thank you.

Does the AIA make a standard template available with all the layers already included?  You might want to check.  Otherwise the only two options would be 1) find someone (an architect?) who follows that standard and ask if they would be kind enough to share a template or 2) get started on creating one yourself (a tedious and thankless job).

Thank you John. I might try to create layers for just the disciplines I work in.

I'd share a template with you if I had one but the two architects I work with follow their own standards when it comes to layering.  Good luck.
