You can edit the print scale of a view by accessing the view’s properties.
To edit a view window’s print scale when it is the current view window:
Select View > View Properties, or right-click in the view window and select View Properties.
In the View Properties dialog, select the desired scale from the Scale drop box.
Click OK.
To edit a view window’s print scale in the View Manager:
Select View
> View Manager, or click the View Manager button on the Advanced
View Control toolbar.
Select the view to edit and click the Properties button.
In the View Properties dialog, select the desired scale from the Scale drop box.
Click OK.
A view’s print scale is the ratio of units on paper to real-world units. If the scale is set to 1:1 (12" = 1'- 0"), twelve inches on paper will represent one foot of your model. This would be a rather large printout. A scale of 1:12 (1" = 1'- 0"), however, would result in a smaller-scale view when the drawing is printed because every foot is represented by only one inch on paper.
Note that if you change the print scale, your 2D plan does not scale on the screen. It will only be scaled on paper when you print the drawing. The scale you specify in a view window’s properties has a direct link to the Print to Scale option in the Print dialog.
Changing the print scale has no effect in 3D views, neither on the screen nor in printouts, unless it is an elevation view. This is because a model being viewed in 3D does not have concrete measurements like a flat, 2D view has.
Things like text and dimensions will scale on the screen when you change the scale because they are specified in real-world units, whereas the model on your screen is created using units that are only proportional to real-world units. Regardless of a view’s scale, things like text and dimensions will always print out at the size that was assigned to them at the time of insertion. For example, if you inserted text that had a 1/2” text height setting, the text will be 1/2” on paper, regardless of the view scale or what the text looks like on the screen.
