After importing files there may be information a large distance away from the drawing details. The drawing will appear as a small dot on the screen. Another symptom is difficulty in centring the plan in the Print Preview dialog.
To rectify this situation follow these steps:
1. Locate and zoom in to the drawing.
2. Use Select Window to highlight the drawing details.
3. Use Modify|Invert Selection. This will de-select the drawing.
4. Wait until the drawing is de-selected and then action Delete.
5. Select Zoom All.
The drawing should now fill the screen.
Note that if additional layers are displayed the issue may reappear and the above steps can be repeated.
