Modifying Slanted Walls and Columns

Note: You cannot slant a wall whose reference line is centered.
Stretch a slanted wall/column by moving its top or bottom edge up or down along the wall plane (Use Stretch slanted height for walls, or Stretch height with fixed angle for columns, in the pet palette.)
Stretch a slanted wall/column vertically. (Use Stretch height in the pet palette.) As you change the wall height, the wall thickness remains the same but its slant angle is adjusted accordingly.
