How To Set Scale In Autocad

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 beneath explicate how to re-calibration a cartoon from metres to millimetres.

Set the correct map units

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

Change the model file from metres to millimetres

AutoCAD now knows that each unit in the map is 1 metre in the model. However, printing in AutoCAD is based on ISO paper sizes using millimetres and then in society to print at a specific calibration you lot need to convert the model from metres to millimetres.

Press Ctrl + A on your keyboard to select all elements in the cartoon.
Type 'scale' in to the control bar and printing enter.
AutoCAD will ask 'SCALE Specify base of operations bespeak:', blazon '0,0' (without the quotes) and printing enter.
AutoCAD will ask 'Calibration Specify scale cistron or [Copy Reference]', type 'yard' (without the quotes) and press enter. You lot may need to printing the zoom extents button to view the information.

This will have changed the drawing from metres to millimetres.

Creating a print file at a specified scale

In the main AutoCAD map window select the 'Layout1' tab at the bottom left.
On the layout page, delete the existing Viewport to give you a blank page. Do this by clicking in one case on the blackness box that highlights the extents of the Viewport (it will modify to bluish to point that it is selected), then press delete.

The currently available drawing scales are displayed:
Select 'Add...' to add together a new scale, and complete as required. 'Paper units' are the units on the finished print out, 'Cartoon units' are the units within the AutoCAD model. Then to add together a custom scale to impress at 1:ten,000 complete as shown below:
Once completed, click 'OK' to close the window, and once again to close the 'Edit Drawing Scales' window.
Select the Viewport again so that it is highlighted in blueish.
The current cartoon scale will be displayed in the scale option drib downwardly:

You lot can at present print your map at the specified calibration.
