Hi @modriderapktraffic,
There's a few different options when it comes to managing templates on Projects. Each with there own benefits. I can mention some of the things I've found useful. Also, is your project operating through ACC?
One thing you do always want, is a strong company driven Template that aligns to the CAD standards. If you spend a good amount of time developing your company Template this will pay dividends over time. But it will need managing once setup. Keep the master template locked down, and have access for all users to a copy somewhere. Or, you can move a copy to a project folder once it's setup. This works well for any edits that happen along the project cycle. You can capture the updates in a project template, then decide if you want to move these amendments to the Master Template for future use on other projects.
Having mentioned that your project is large, assuming you have multiple users then I would prefer to use Reference Templates - https://help.autodesk.com/view/CIV3D/2025/ENU/?guid=GUID-C4820724-DF07-4580-906F-65A88B935395.
This will allow a BIM/CAD Manager to control what information is being used in the template, that in turn can be applied and updated to any working models. This is excellent for multiple users especially when you're working to client standards and the presentation and styles etc. can be very fluid. You can have a team of users who dont have to worry about updating template information and having people jumping into templates altering different styles all the time. Also works well when you have presentation models setup.
You can also combine Reference templates with a company template, for example if you have a well developed company standard template but want to merge in client specific styles then this will work well also.
In terms of Data Shortcuts, they're a must for all projects. On large projects I would look to have most objects seperated out to their own DWG's then Dref'd in where needed. I usually never have more than one surface created in the same DWG.
I hope this helps. Plan the template well and you'll have alot of happy Civil 3D users.
