If you have internal polygons on a different layer than your boundary, and want to remove the polygons from your boundary, follow the steps below: Choose Basic or Advanced

Basic Users
  1. Open a New Map of the Boundary layer, then lay the Generic layer of the polygons over the boundary (Add to Current Map).

2.  Go to File -> New -> Boundary Layer

3. Under Special Tools, click Copy From Layer.

4. With the preview of the boundary showing, click Next, Next, have Copy Spatial Data checked, click Finish.

Repeat steps 3 and 4 for the polygon layer. Instead of seeing the boundary in the preview, change the selected layer to the polygon layer. Click Next, Next, Copy Spatial Data, Finish.

5. Under Select Types on the left side, change the select type to Select Intersection.

6. Under Action Tools have it on Select and Select Point, now select the polygons you wish to remove.

We will want to select all of the polygons at once. To do this, hold down the Control Key on your keyboard and click each polygon.

7. With the polygons selected, click Divide by Selection, found under Divide tools on the right.

8. Select all of the polygons again and click Delete Selection found under Edit Tools on the right. This step will need to be done twice to delete the internal polygons out of the boundary.

Once we have selected and deleted the polygons twice, you should not see hash marks over the internal polygons.

9. Go to File -> Save AS

10. Select the G/F/F. Click OK.

11. If you want this layer to now be the frozen field boundary, you will need to find this new boundary layer in your Management Tree, right click on the dataset and click Set as Field Boundary.

Advanced Users
1. Open a New Map of the Boundary layer, then lay the generic map of the polygons over the boundary (Add to Current Map).

2. Right Click on the map and go to Edit Layer

3. The Generic Editor will open. Under Special Tools on the right, select Vector Overlay.

When this box opens, check the box next to the layer that is displayed under Select Layer to Overlay.

In the white box you should see Your Field name followed by the Grower name. Click OK.

4. Under Select Types on the left side, change the select type to Select Intersection.

5. Under Action Tools have it on Select and Select Point; now select the polygons you wish to remove. (When you select the polygon, just the polygon should appear 'highlighted')

6. With the polygon selected, click Delete Selection, found under Edit tools on the right.

7. Continue this process until all of the polygons have been removed.

8. Once the polygons have been deleted out, they will no longer have hash marks across of them.

9. Go to File -> Save AS

10. Select the G/F/F. Notice the Operation is probably not on boundary anymore.

We will want to select Boundary as the operation before clicking OK.

11. If you want this layer to now be the frozen field boundary, you will need to find this new boundary layer in your Management Tree, right click on the Dataset and click Set as Field Boundary
