I'm not, but what I've done in the past is this.
If 3D models were not present on their website, I would check other manufacturers of similar products to see if I could find it on theirs. If that fails, contact Elgin via their customer support or your account rep and ask to get 3D models that you need. Most companies do 3D now and are happy to supply them upon request. I've done this with several vendors and have successfully received 3D models from them.
Hope this helps!
