To draw objects on a base layer:
- Select your existing map and click Home | Add to Map | Layer | Empty Base.
- Right click over the new empty Base layer in the Contents window and click Edit Group. The base layer is now editable.
- Select the item you want to draw (text, polylines, polygons, points, etc) from the Insert section on the Home ribbon bar tab.
- Draw the objects over the map. Create as many objects as you wish.
- When you are finished, right click over the Base layer in the Contents window and click Stop Editing Group. The base map, and all the drawn objects, will now move, scale and resize with the original map.
- If you want a separate base map file with these objects, turn off the original map layer and all the axes in the Contents window (uncheck them) and click File | Export to export the new base layer and drawn objects to a new file (ie. BLN or DXF).
If the objects are already drawn on top of the map, or you want to draw them floating on top of the map, and you just want to export them in map units, you can simply turn off the visiblity of the map and export them. To do this:
- Uncheck the map in the Contents window, so it is invisible. Uncheck any other objects, so just the objects you want to export are visible.
- Click File | Export.
- Give the file a name, choose the export format and click Save.
- In the Export Options dialog, select Map as the Scaling source. The File Rectangle coordinates update with map units.
- Click OK the file is exported. You can turn on the visiblity of the map.
