Editing the Footprint of an existing Building or Zone is similar to the initial creation process with a few simple additional steps and rules.
Select the Item you wish to Edit (based on the rules outlined below)
Click the Edit button on the Edit Toolbar
A series of Strokes are created based on the existing item Footprint.
Edit these Strokes in the same way as you originally sketched the item. You can add/erase stokes using the eraser/squiggle.
Once you have sketched the new Footprint click the Accept button in the Edit Toolbar.
[You can use the Reject button to cancel the update and remove the Strokes]
Updating Building Footprints
When updating Building Footprints the following rules apply as to how the new Footprint is assigned to the Building.
1. Selecting the building by double tapping on the ground storey, selects and edits the entire building
2. Selecting the building by double tapping on any other storey, will set and show the working plane and all storeys above will be update
3. With an individual Level selected, the updated Footprint will apply to that individual Level
