SmartDraw

Where this software really shines for our business is its ease of use for submittal drawings when bidding and creating contracts for jobs. It allows us to empower our salesmen to create their own submittals without the expense or training needed for some of the more "professional" suites. This means for smaller projects we do not need to tie up our senior estimators, leaving their time free and better spent with CAD. What this means is that for job cost, we are able to use lower wage employees to perform simpler tasks and not eat into the margins of a job from utilizing higher paid engineers.

It can be a bit finicky in trying to get it to do exactly what you want it to do. Its ease of use sometimes means that you are fighting those very elements that make it easy to make it do what you want it to do. Snap to grids and the like, while toggle-able, provide an annoyance when they should "just work".

It's very easy to draw up a basic house floor plan.

Limited symbol options specific to interior design. If you use too many JPEG images within the file the system struggles to convert to PDF. (which isn't the case with my other design software). Often glitches when opening files and/or is very slow to open existing documents.

Great software for flow charts and process maps. Used extensively for 3 years under a one time license.

Was only available for Windows at time of last use, since then it has moved to a subscription, web-based platform which is a significant cost considering other better-value or free softwares that can do the same.

Very easy to draw flowcharts.
Easily import and export visio. Available at cheap price and can easily replace visio i believe which is much costlier. One can use its rich library of colours.
Templates help alot to quickly built mocks.

When I used i didn't find multiple user facility.
