Maybe it is because I am totally new to modelling and have not used other similar tools, but I find the tutorials and guides to be lacking.
They often show very different versions of the application and assume a level of knowledge that people not already proficient in some other modelling tool will not have, I may be wrong but your material looks like it has been produced by the developers which is often a bad idea because they know too much.
Even simple things like taking extra time to highlight what is being clicked on would be a big help ... if the material was up to date.
I'm presuming that one of the ways you get new customers is for people to try out the product, and I suspect that you are losing some people at the first hurdle.
I have a background in programming and training so I don't think my issue is me being slow ... but I admit that could be the case.
If I manage to get proficient then I'll see if I can supply some YouTube videos of my own, but in the mean time it would be great if you could put more resources into your materials.
