Your ariticle hits home but I'm just an old timer with not much experience with MCAD or AEC as of yet. So by starting later I did not suffer through the evolution of software to what it is today. Whether bad or good today, it is the best we have to date. I will always depend on you who have the experience to push for the changes that I will use but don't know I need it as of yet. If that makes sense to you. I know your article made sense to me. Keep at it sir. Great job.
