Do you really think about product merging you talked above? Do you really imagine features from one side (parametric) merged to the other one (explicit) and vice-versa. Do you really think this as PTC/CoCreate objectives?
Look at famous previous acquisitions: Dassault/SolidWorks, Agile/Eigner, UGS, etc. I never seen any product merge combining best-of-both. Or it needs decades!
From my point of view, this acquisition is just a tactical, commercial, market share strategy.
It will serve PTC to react to new competitors (SpaceClaim)
It will serve CoCreate and HBK to get money, and to make a new market recognition.
Innovation, new products are facts from new companies (PTC a long time ago, SolidWorks, Space Claim); in a preferred way founded by some people coming from the acquired companies. See curriculums of executive of CV, PTC, SolidWorks, SpaceClaim.
This event is potentially able to sign for a birth of a new company founded by former CoCreate people.
