I forgot the name of that program you use to make the sketches. What was it? I’m working on a post for 1st date location seating and need some seating sketches, bar, table, couch etc.
The diagramming/layout tool I’ve used is what I think you’re talking about. Omnigraffle is best tool I know for mindmap type brainstorming and layouts for events, easy drag and drop everything, Mac only though. https://www.omnigroup.com/products/omnigraffle/
