Ok should be simple enough I'm just not sure how or if this can be done, i have imported a model from another program but for some reason its distorted , if you take a rectangle and slide one of its edges a little bit you would get the same effect of distortion , is there any built in way to simply grab one side of a model and move it with AM moving every other point to the correct position?

with a distortion box.

select the group you want to bend and press the distortion mode button (next to modeling mode)

In the options panel you can set how many part a d box has.
