Upon further reviewing, i think this model would be easier to place and/or use if they didn't slant at the bottom.
This won't be problem if you only use this as a destructable, since you can lower the height, but as a doodad you sometimes want to lower the model into the ground for a more pretty result.
I think overall if the model was lowered slightly below base, this would resolve the problem.
It's also hard to click the model inside the editor, when adjusting sizes, even the clicker helper is really small.
