I'm confused about blender. It's for animation? what 3D modelling capabilities does it have?
Kitchen sink intended to be used to make anything, supports a few different "styles" of modelling but is traditionally rooted in polyagonal modelling. Everything you have seen in a video game (tank, gun, person, alien, map) is possible in Blender. It might be worth skiming through a variety of videos on Blender to see what it's like, some show boring features whilst others showing
slightly crazier uses.
All of its features are optional and there are many ways to achieve each task. It's not as structured or strict as a stack of operations in a CAD tool, your modifications to your model are more immediate-mode (permanent) instead. If you have only ever used stacks then that might scare you, don't let it, it's just different.
I've not used the animation features in several years and before that I only ever lightly touched animation features when using 3Dsmax/Gmax. Not my cup of tea.
