I've seen a lot of people asking about methods for creating detail sheets so I thought I'd share a method I just learned today.
I have four projects that will be using identical detail sheets (why the buildings are not all in the same project is a long story so please just accept the circumstances as a teaching tool) and I've be struggling with the best method for copying the detail sheets from one project to another. I have about a dozen detail sheets; each with up to thirty details per sheet. Each detail is a separate view file with a single model space view.
The detail view files are copied from the original project by dragging them from windows explorer directly into the project navigator (holding the Ctrl key down while dragging will create a copy). The sheet file is then copied to the new project by copying in windows explorer and pasting to the sheets tab of the project navigator. In order to do this the sheets tab must be in the explorer view. For some reason this process keeps the names of all the model space views placed on the sheet but deletes the numbers so each view needs to be renumbered.
Since this process maintains the original external reference paths, I then go to the Reference Manager program and update the paths of all the details to the new sheet. Once this is done all of the detail numbers and titles need to be linked to the new sheet by opening each detail and dragging the callouts to the appropriate detail on the new sheet.
It sounds a bit cumbersome but so far it's the best method I've found. Hope this is clear and helpful.
