Sheets and Scaling

Good day,
I am new to V100 but had a little experience with V20 where there was no
difficulty creating a 1:1 drawing on the 2D sheet and moving it to A4 sized
sheets for printing. Try as I may I cannot do likewise with V100. Could
someone guide me with the necessary steps, taking a simple example e.g. a
rectangle 1000 mm x 500 mm?
