haveing a problem

So I'm having a little problem turning my models into class files, I followed a tutorial on how to do it, but when I went to recompile, it got some errors in my models Java but I have no idea what to do ( I exported the tank as a turbomodlethingy Java).
and I cant find any tutorials on how to fix it

you see I was trying to figure out how to make trapezoids in the Java for my tank

but to see what it would look like I need to see in in game

it would be nice if I could figure this out soon cause I would like to get this out in a content pack before someone else put m1a1 in a content pack

There is no way to make trapezoids using Techne. Its the main reason Billy didnt want to use it to make the models for his/partly mine now airplane pack.

You have to do it in the java file.
I don't have the best understanding of it,
But I think I get a little bit on how to do it, but I want to figure it out
By doing it ,
and seeing if it works mostly just trial
And error.

This should look familiar if you've looked inside the generated code. Mostly, it's just going to be a matter of tweaking vertices to get them where you want. Basic trig should be sufficient to get the coordinates you need. Failing that, eyeball it. Just make sure all the local vertices touch at the same point.
