clearly per unit = meters The above values are therefore good if you print from the model, while you die from the layout.
4500 (meters) horizontal extension in scale 1:50000 correspond to 9 centimeters plotted, which are quietly in a sheet a6, you in what format do you want to print?
I should print the table in a3 format. to print from the layout how should I do? on the layout I inserted the sheet square and the table name, unlike the model.
to print from the layout you have to make sure that the print scale is 1:1 and in non-inch millimeters as in the sample file.
then if you use the layout you have to create in the layout a window with the Italian finmul command or English _mview and zoom appropriate to the print scale you want.
in your case after creating the window clicks inside the window, with the zoom command from the scale option and check the scale value 0.02 (which corresponds to 1000:50000=0.02), at this point with the comand pan centers the drawing in your window oppresses from the paper space move the edges of the window until you frame the drawing.
Now you can print the layout by selecting the 1:1 scale (millimeters), obtaining the 150000 scale polygonal.
this is the step-by-step procedure, which I hope to have clearly described, for the use of layouts and stairs.
First of all I suggest you learn how to use the stairs with the various steps to learn how it works, then if it can be convenient you can use other utilities like the autolisp application that I recently updated in the post managementfl-planning-in-case-di-layout
