If you need to zoom or pan the map view while drawing a polygon, it will need to be drawn in sections. The sections are then saved to a single file and edited to create the final polygon object. The process is as follows: Before you start drawing be sure to clear the drawing layer by drawing a bogus polyline of two or three points. Select Edit -> Select All Objects and then right-click on your polygon to delete it. This will also delete any other extraneous drawing objects that might not be visible.
- Choose Draw -> Polyline (NOT polygon)
- Draw the first portion of your boundary until you get to a place where you need to zoom in or change the map view. Double click the last point to complete this first portion of the boundary.
- Change your map view and then do Draw -> Polyline again and pick up drawing where you left off until you need to change the map view again. Double click the last point on this portion of the boundary.
- Repeat step 3 as needed until you have finished the boundary
- Choose Edit -> Select All Objects and then right-click on any part of the boundary and save to a BNA file.
- Edit the BNA file to remove all the intermediate "header" lines.
- Copy the first set of coordinates (line 2 in the file) and add them as the last line in the file.
- Update the "number of coordinate pairs" in the header line (item #3 in the first line).
- Save the file
