CAD Usage, Good vs. BAD, or Inexpensive vs. Expensive



     Why does it seem that there are some CAD programs that are very intuitive and inexpensive yet nobody uses them and at the same time there are  other programs that are very difficult to use and very expensive however these program seem to be among the most popular?

     Before anyone makes any assumptions or jumps to conclusions that I may be out to criticize the software manufacturers, like Autodesk, Bentley, Dassault, or Siemens,
"I am not out to bash the software manufacturers". 
I just want to point out, with the programs that I have used, that some were easier to learn than others, some were great for getting a product ready to use and some are just plain old time consuming memory hogs.
     
     By the way, the most extensive experience I have is with Autodesk software (20 years+), and the main software of choice has been AutoCAD.  Out of all of the Autodesk products that I use, the easiest to learn and use has been the Autodesk Homestyler®  for basic home design. Anyone can create a basic 2D floor plan layout print it as a 2D, or convert it to 3D, and save it to either a DWG (AutoCAD), or Revit (*.rvt).

     The one of the most difficult Autodesk products to use, (and expensive too) is Revit. I have found it easier to just start and create my projects from Homestyler® and then convert to Revit. Setting up a standard to use, and maintaining visual styles was and continues to be very challenging, since it seems every project has a different procedure. Perhaps if I was the project captain or chief it would be different, however, as a consultant you are subject to using the customers’ standard, and unfortunately since Revit is fairly new, there doesn't seem to be any real standards out there. 

     The best bargain for my $$$ has been using the Punch CAD software. Again, as a consultant I've been able to use this software to create 2D and 3D floor plan layouts. The only drawback has been, "not being able to convert to anything other than AutoCAD". Hopefully the newer versions of this software will also convert to Revit, so that any BIM items will be readable in Navisworks (yet another Autodesk® software product). To me this is on par with another Autodesk software product that I use, "Freestyler" which was an inexpensive 2D drawing program (it was only in use, or for sale for 2 years and then discontinued by Autodesk).

     Other CAD systems that I have used include ProEngineer (Pro-E). I actually have a few drawing examples shown on the Grab CAD site of my work. I have also used Personal Designer, (does anyone remember Personal Designer? ) which was a good product developed by Computervision, and now owned by PTC (ProEngineer). From what I have read (refer to hyperlink), due to the high cost, which was over $3k back in the 1990's, not including the computer, and also due to poor marketing, the product has been discontinued. I have also used Google Sketch, Bentley's MicroStation, Microsoft Visio, for basic graphics risers and flow charts and finally Micrografx Designer. Micrografx Designer is actually a Corel product and my main use for the product is to create graphics. Just like Punch CAD, and Autodesk Homestyler®, I found Micrografx Designer fairly easy to work with and converting the files back and forth to be used with other software also fairly easy to do with minimal amount of glitches.
