- The color coming up as Black is probably normal back then, 20 years ago.
- Zoom not zooming as expected usually means you have some space dust way out in the drawing.
When zoomed all the way out, do a "Select All" and see where the selection nodes appear.
Hold the Shift key and drag the Selection tool over the area that your drawing is located.
This will deselect your drawing and leave the rest selected.
- If you have "Named Views", use one to get back to that area.
Another option to try is the "Home" key to put the 0,0 coordinates in the center of your screen,
then use "Zoom Printed Size" to bring you in to 100%.
ACTUALLY V3.x had all the colors current versions have now; but the converted file made them all black regardless of layer [I'll just change them as needed, so not really a problem].
I did find some 'space dust' & deleted it; but the zoom IN still did not work.... so guess I can only use the Zoom window tool.
Lastly, the conversion made my 3/16" = 1'0" scale used to draw my house plan [there was no 'paper space' window that scaled the actual/drawn size down for printing!] to change in the V7 copy to 'full size' or 3/16 of the real size; is there a way to redraw the new drawing version to be 64 times bigger [to be in full size in model space]?
