When within the annotation canvas and the icon annotation mode, users can drop icons on images to provide further information. When an icon is selected from the Icon List, it is dropped in the centre of the image. In order to move this or any other icon, it must be selected. A selected icon can be identified by the cyan frame around the icon.
Once selected, an icon can be re-positioned by tapping and dragging the icon. In order to facilitate easier re-positioning, the icon will snap above the user's finger, so that they can place the icon precisely. Once placed, the new icon position can be finalized by tapping Save.
For information on linking icons to form fields within the building information plan, see I've placed an icon on my site plan. How do I link it to other parts of my preplan?
