Start by selecting the object you want to change or edit.
A box will pop up with all of the object properties that can be edited.
For tables, you can give the table a name, change the type of table, change the color, change the chair count, choose where the chairs will sit, rotate the table, and clone the object.
You can also change the object type by selecting the object and using the drop down to make your updates.
Any change you make is automatically reflected on the floorplan.
If you want to change the details of an object for all events, click the pencil icon in the object menu. A box will pop up allowing you to select “Just this event” or “All events.”
