Not sure what you mean. RISATower and TnxTower are the same program. TnxTower is just the newer versions.

What libraries are you talking about? It's been awhile since I used the program, but if you install the program you should have everything. I guess, there could be some aspects / libraries (Crown Castle?) that only unlock when you have certain licensing or permissions.

Josh:

I thought I heard a while back that TnxTower had morfed into another program name - bought up by another entity?

Nope. Peter is still the guy as far as I know. I checked in with him about 6 months ago. We chatted (via e-mail) about some of the changes at RISA, how that might affect him and his program. Pretty brief really. But, I got the impression that he was expanding a little, not the other way around. Working on a Foundation module, adding another engineer to relieve some of the support and sales burden. That sort of thing.

There isn't much as far as tutorials or such. There are some "hand verification" problems on their website. I remember those being helpful to me when I first started using the program.

TNX doesn´t have many tutorial about analisys .

From what I remember, TnxTower does analysis, not design.

YOU chose the member sizes and input the data (design), and the program analyzes the model you have created to see if the design is code compliant.

you can use ASMTower. it is more easy and accurate design. it has fantastic 3d view.
