Trouble displaying drawing in Viewport

[grain]

I have a drawing made in model space and displayed at 1:100 in an A4 Viewport Landscape layout. No problem, but when I open a second layout

using an A3 paper size I assumed the drawing would automatically fit if scaled at 1:50, however, the drawing appears cropped. Please help me understand what I may be expecting or doing

wrong.

The difference of scaling between metric paper sizes is the square root of two. So you would have to scale the A3 to 70.7143 for the two sheets to match.

 

However, with the paper margins and any title block requirements, the actual scaling could alter so that the viewport areas would match.

If you were to use an A2 paper size at 1 to 50, the viewport areas should be much closer.

@eldon has certainly given you the correct answer. Our title blocks were an A1 sheet but we plotted hard copy & PDF most times to be a A3 sheet. The was produced by setting the scale factor in "PLOT" to 1=2 so a 1:250 viewport would be 1:500 in an A3, so objects could be scaled. 

 

So we never mixed and matched the title blocks size. Only used one size so you probably need to think about that. If you stick with A3 you can probably have 2 viewports per layout at 1:100.
