Have you heard of Sketchup.com? It’s a free software you can use for creating floor plans, layouts, exhibits, etc. If you don’t have the budget for a CAD (computer aided design) software program, this is a great alternative with many bells and whistles. You can create 3D layouts as well. Imagine working with your team in designing a new layout for your exhibit building, or providing your team with an exact layout of how the building will look. You can use to distribute to vendors so they will know where their location is.
This tool can also be used whenever you would provide a layout to anyone – including those who rent your facilities. You can add in this service for an additional fee, or as an added benefit, to a promoter renting your facilities.
