My boss does everything Visio. It imports and exports to CAD so we can communicate with the rest of the world. It might be worth looking into.

I dont know why you're being downvoted. I design in autocad, revit, sketchup, visio and inkscape.

I do network designs in visio, 3d BIM models in revit, small home stuff in sketchup, presentation graphics and icons in inkscape.

I export visio stencils to .dwg format which we then bring into revit and turn into 3D blocks for rack elevations etc...

There are so many tools to use.
