You can move an object from paper space to model space (or vice versa) in AutoCAD 2008 by simply copy + paste. But what if the object is scaled and you want to maintain the scale in the conversion? The scale of paper space is 99.9% of the time a different from the scale in model space/your viewport. So, to preserve that relative scale in the conversion you need to do the following:
In AutoCAD…
1) select all the features you wish to convert
2) click the modify drop down > then click change space.
The features you have selected should move from the paper space to your viewport.
Conversely, if you wish to bring a feature from a CAD drawing’s model space back to the paper space, then you need to do the following:
In AutoCAD
1) Double click on the viewport that contains the features you wish to bring back (first make sure the viewport is not locked)
2) Click the features you wish to bring to the paper space
3) click the modify drop down > then click change space.
The features should now be back into your paper space with their scale and location intact.
