How To Set Scale In Autocad Layout

Printing a drawing at a specific scale

AutoCAD typically deals in millimetres, but Ordnance Survey data available in Digimap is provided in metres. The instructions below explain how to re-calibration a drawing from metres to millimetres.

Set the correct map units

Open the DWG file downloaded from Digimap in AutoCAD.
Type 'units' in to the command bar and printing enter, the Drawing Units window appears:
Using the dropdown in the 'Insertion Scale' department select 'Meters' if not currently fix.
Press the OK button to close the window.

Change the model file from metres to millimetres

AutoCAD now knows that each unit of measurement in the map is 1 metre in the model. However, printing in AutoCAD is based on ISO paper sizes using millimetres and so in lodge to impress at a specific scale you need to catechumen the model from metres to millimetres.

Press Ctrl + A on your keyboard to select all elements in the drawing.
Blazon 'calibration' in to the control bar and press enter.
AutoCAD will inquire 'SCALE Specify base point:', blazon '0,0' (without the quotes) and press enter.
AutoCAD will inquire 'SCALE Specify scale factor or [Copy Reference]', blazon '1000' (without the quotes) and press enter. You lot may need to printing the zoom extents button to view the data.

This will accept changed the drawing from metres to millimetres.

Creating a impress file at a specified scale
