69:). Leonid Raiz and Irwin Jungreis obtained from PTC a non-exclusive, source code development license for Reflex as part of their severance package. In the words of Jerry Laiserin: "While Autodesk Revit may not contain genomic snippets of Reflex code, Revit clearly is spiritual heir to a lineage of BIM 'begats' — RUCAPS begat Sonata, Sonata begat Reflex, and Reflex begat Revit."
80:"After receiving several hours of instruction in the software architecture of Reflex from Reflex developers, we decided not to use it as our starting point because of several important differences at the very foundations of the software. At that point, we put it aside and never looked at it again. ... Revit was not based on Reflex. No code from Reflex was used...."

PTC had identified the architecture, engineering and construction market as a target for its parametric modelling solutions, and bought Reflex to expand into the sector. However, the fit between Reflex and PTC's existing solutions was poor, and PTC's Pro/Reflex gained little market traction; PTC then

Some accounts of the date of this transaction vary: Beck
Technology, originally an internal group within Beck Construction, says it acquired the intellectual property rights to Reflex from PTC in 2000.
