I work in drawings that sometimes have upward of 100 layout tabs (a contract requirement). These viewports are set up at 1" = 100' for utilities mapping. One drawing may cover several miles with information specific to each viewport set on layers created specifically for that viewport. This is done so as to not allow information in adjacent viewports to be seen in the current one. The viewports are often turned at various angles as they follow the given route of the C/L and trhus the text is angled differently in each viewport.
My question is how do I add new layers in model space and keep them from showing up in the existing viewports in those layout tabs? I recently had to add some new info and create a set of new layers. I then had to go to each layout tab which contains 1 or 2 viewports and freeze the new layers. How can I avoid this? The information is placed into the drawing in a coordinate system, so placing it somwhere else in model space is not an option.
Any help will be appreciated.
