Having issues flattening with your model surface? Here is a simple trick to get it all align to one axis.

1 Go into edit mode by pressing the Tab key.

2. Select the vertices, edges or faces you wish to align.

3. Press S Scale and then press either X, Y or Z (base on the axis you want to flatten the selection) and then 0.This sets the selection to move to 0 hence flattening the surface.
