Thank you for your continued coverage of IronCAD and it's history. I was an early user of Trispectives and found it far better than anything else available at the time. It ran well on my Windows 95 PC and gave me the ability to do 3D solid modeling, renderings and animations at a very reasonable price.
All of this is common place now but in 1995 this was pretty amazing stuff from a Windows PC and $500 software! While others were paying 10K+ for Pro-E and another 10K+ for a Unix workstation I was making a nice living off Trispectives with 3D solid modeling, animations and renderings on a very affordable Windows PC.
Here are some examples of work I did with the software in 1995-1996: 3D form studies, color studies, 3D printed models from .stl files, renderings and 2D documentation. Again, all of this is common now but it was well ahead of the pack in 1995 and at a price that could not be beat!

I first encountered Tri-Spectives in its infancy, at (I believe) NDES in Chicago. I was working for a PTC/Computervision/Autodesk reseller at the time, and was given a copy. I believe I was somehow placed on their reseller list, as I continued to receive quite a bit of correspondence, information, and updates from the company.

But, oh, my! The ease of use! The drag and drop features! The drag and drop animations! The (what we now call) direct editing!

I honestly thought I was seeing the future.

Sure, there were issues with interoperability, and I encountered some with internal accuracy (I was told it was just an ideation tool, not really valid for documentation or downstream applications, i.e., CAM) but just the same it was a revelation. Certainly this will revolutionize the industry!

Ironic, then, that even some time into its IronCAD reincarnation, they were touting in ads that "100s of customers can't be wrong." 100s?

So, yes, Ralph, thanks for following up on this very interesting product, and for the reminder that the CAD industry never plateaus and gets boring.
