New Building Prototype

Anonymous — Tue, 21 Feb 2017 15:19:10 GMT

Hey guys. We are doing the second building in a three part series of the same school. This project will be the same two architectural links, just mirrored. I'm trying to find the best way to minimize the amount of rework for my team. I was thinking about breaking the model into two separate models and linking them into a "main" model and mirroring those links, as trying to mirror MEP systems seems like a nightmare. Thoughts?

Here is the old school.

Here is the new school. (mirrored)

Hi Brett,

I am not sure if this will work, but you may can try it.

Break the model in to two ("Old School & "New School") and link them into main model as you already did
Now make a COPY of "Old school" model and let's name it "Mirrored model".
In this Mirrored model Rotate the Project North and save
Open "New School" model and keep "Mirrored model" open in the back ground.
Copy everything from "Mirrored model" and Paste it in "New school model"

And let me know if it works.

Unfortunately, that would only rotate it. That wouldn't solve the mirroring issue. The new orientation is rotated and mirrored.

Hello,

If all your components are absolutely symmetrical you can mirror them, if not, I suggest you to go the hard way, so you will avoid using non existing components. We avoid to use mirror, just rotations.

You're right. Mirroring MEP doesn't work. Neither does it in architecture. The real life equipment and fixtures don't usually have a mirrored option and you also have that hot water on the left and cold water on the right thing. Then there is that mother nature thing creating different heat and wind loads on the building. Plus, the architect is going to have their own similar issues and the building won't be an exact mirrored copy.

Hey guys, thanks for your suggestions and comments.

What I believe the best thing to do is to break out the model into two links and bring them into a new "combined" model. Within that model, I've rotated the MEP links to align with the new building orientation. After that I set the link in the view template to "by linked view" and that brought all of my annotation thru to the new model. I still have to rotate the keyed notes, and re-pipe the plumbing fixtures, but everything else seems to work.

I realize the energy model will change, and the loads will vary from the original, but I think this will still save us a lot of time reworking the project from scratch.

Thanks again for all of your input!
