Visio basic is for org charts, office layouts, stuff like that. Think of it as PowerPoint with some drafting template objects. I was the VC backer of Visio when it started in 1993, but it was gobbled up by Microsoft and integrated into Office in the late 1990’s. The Pro version is fully featured for architectural, engineering, HVAC, piping and pneumatic design, etc. The Pro version of Visio is available for purchase (about $500) or through Microsoft’s cloud-based service for a monthly fee. In many respects it is a template-driven version of the original MacCAD or Claris CAD system, the long time high water mark for UI design and productivity. Within Microsoft, Visio is a backwater product and as such I don’t normally recommend it to new users. I have 20 years of legacy drawings corked up in Visio, so I’m hostage to it and still run the 2002 version under Windows 10 under Parallels on the Mac. Visio does not have parametric geometry capabilities like F360, but is object based with layers and most of the flexibility of Autocad but with a much better user interface. If I had to choose a package today for 2D drafting I would consider Ashlar’s Graphite (which is parametric) or Rhino 2D. The learning curve on all these CAD packages is steep if you want to be productive, and once you have a library of drawings, you are held hostage, so choose wisely.
