Are the blocks really free?  What's the catch?  I find it difficult to believe people are just going to give away high quality content out of the goodness of their hearts.  Personally, I think you posted here just to get some free exposure for the website and nothing more.

Jeez, I just noticed this....

"This store requires a minimum order of just $1."

So there is a catch.  Nothing in life is truly free.  So I pay $1 and I can get a full set of drawings/details for a luxury apartment building or a high rise office building?  Amazing!  All one has to do is download the blocks, slap them on their own title block and border, and submit them for approval.  Boy, it doesn't get any easier than that.  Why I could become the next Donald J. Trump and spend no more than $1 of my own money.  I could be a billionaire by the end of the week.

Please send me all the drawings I need to do a 30-story high rise condo.  As soon as I receive the CAD drawings I'll send you my dollar.  Please hurry, I want to be rich really bad and really soon.  Thanks!
