I am a former Medical R&D guy who spent many years in the 3D graphics arena writing code. During my time I had the good fortune to become acquainted with Robert Lansdale.
3D translations are one of the more complex areas of 3D software development. All translations are subject to some level of interpretation. Some interpretations are more technically correct while others are more aesthetically correct.
PolyTrans is the only translator I know of that does a robust job of translating from a plethora of formats to another plethora of formats!
If you want a translation that "looks good" but is not technically accurate perhaps, on very rare occasions, PolyTrans is not for you. But having said that you will be passing by the one translator that can go from practically anything to almost anything else.
If you are not getting the translation you want I'm betting that it is either the original model and the way it was modeled or a translator that has some technical flaws that make certain models serendipitously look better.
I never write reviews but when I saw the egregious bashing done by someone who is a newbie to 3D modeling I had to respond for the sake of all the 3D modeling community.
Modo itself has many modeling issues. For example, it has no arc construct only an arc wedge! This causes problems when you want to create a surface patch by running and arc down two spline guide rails, as you get stuff in the middle you don't want.
I tried to show my email address for the sake of transparency and legitimacy but could not get the site to do so: email@example.com
I suggested my work buy this product to translate CAD files. That was a mistake. First signs of trouble came when I asked how to use the software and I got a novel of text which seem to all affirm that Robert Lansdale is a genius and everyone else on the planet is stupid. A simple tutorial would have been great, like I'm used to with all the other software I use daily.
Robert Lansdale really thought it was important to "change my perceptions". He also told me at one point that this company is an experiment in human psychology.
Yikes! I just want to translate files to do my job for the company I work for.
At one point I showed him how MODO Power Translator tessellated the mesh of a part of the assembly versus his Polytrans product, and to me it was a night and day difference that the MODO Power Translator looked MUCH better. He then told me that that's my perception, but if I knew as much as he did I would know that his is more technically correct. Wow. I let him know that I'm in marketing and that my whole job revolves around perception.
At one point I was trying to cover my butt at work since I had advocated buying this product, so I asked Novaedge if I could get a refund. Robert started sending emails to people in my company telling them he couldn't work with me, and on and on. Basically trying to throw me under the bus to protect his reputation (and fragile ego).
I could go on since I archived every exchange with Robert. It's hard to believe that such a terrible company can have a place in the marketplace.
So, in summary, this product is a good idea and I wish more companies would compete against this terribly run company. The software looks like it's from the early 90's as well. There's too much Robert in Polytrans
Seamless model transfer from SolidWorks to 3ds Max. Great product.
I had a good experience with the product. It isn't overly intuitive but the learning curve is reasonable.
OBJ output is the best for 3d work from PolyTrans, I've found.
I would recommend PolyTrans.
Our company purchased Polytrans for use with Quest3D, and while the exporter itself is quite fast, the Polytrans program itself is quite messy. Polytrans does NOT support multiple UV sets, so if you are intending to apply any sort of texture layering system with different UV coordinates for each map (eg. diffuse+ambient occlusion) to your scenes this isn't the program for you.
Finally, developer support was quite poor. When contacting the developer on the above issue, they were stubborn, unhelpful, and they would only quote how many years they have been working on the product and therefore they are correct and I am wrong.
It is lucky the software is quite quick, otherwise I wouldn't be using this at all.
