How can I know the right scale of my drawing to write it in the plot bar?

Well, a good rule of thumb is to draw all your drawings scale 1:1

then you might ask “My drawing is a building; and is too big to be drawn 1:1” but you can change your viewport scale from:

1. Click the border of the viewport whose scale you want to modify.
2. Right-click, and then choose Properties.
3. In the Properties palette, select Standard Scale, and then select a new scale from the list.

when plotting choose the scale according to your own required scale, there’s no “right” or wrong here but there are a few limitations such as paper size; whole drawing size, etc….

• You can find the scale options from Model Space, Scale inside plot box.

Hi there maroun, (Cool Name :))

Let me clarify this, you have drawn a drawing in AutoCAD and forgot which scale you used, but now you need to export and need to write the right scale, is this correct?

Yes i drawn a drawing and I need to plot it how can I know the right scale?

Thank you
