I have a slddrt template that I use for drawings. The first sheet has detailed notes and tolerance information, as well as an expanded title block. All subsequent sheets have a simplified title block and no notes.
When I load the template in 2016 it works fine. When I load it in 2015 it only loads the second sheet. I need to work in 2015 because we only have document control software for 2015 at my company.
How can I force it to give me both sheets?
I don't remember ever hearing of an issue like that. Is there any chance the template was saved with SW2016 at some point? On the other hand, if it was I wouldn't expect SW2015 to be able to open it all. The only thing I can think of to suggest would be to open an existing drawing with SW2015, delete all drawing views and annotations that don't belong to the sheet formats, and save as drawing template. Now when using this template with SW2015 both sheets should be there.
What's the difference between a sheet format and drawing template? and Why aren't the changes I made at Tools > Options > Document Properties saved when I start a new Part? may be of some help if you're unfamiliar with any of this.
