Poser has a collision detection system, but that's something else entirely than the DAZ collision detection. The DAZ system is a poke-trough prevention, which you can start if the clothes don't fit properly. No, Poser does not have that, collisions between conforming cloth and the body aren't fixed  automatically, you will have to use the morph brush for that.  Or you would simply make the poking body parts invisible, which makes sense anyway with really tight clothes.

Poser's collision detection is for solid objects only, not for fixing cloth.
