Map Scale overlay aid

If you have trouble setting background colour to transparent post the picture you are working on & will have a go but as said my art package is pretty naff.
A couple of questions for you regarding buildings have CD ver
Tall buildings agree only way I have found is stick on a hill getting the whole building higher without having slopes in adj hex seems near impossible though. Want to do for town say a few high buildings as good spots for MANPADS MGs etc without having road near on slope as blocks LOS down. If you have managed please post so I can look.
Also selecting a specific building have you found a way I saved all buildings on a seperate map & cut & paste but this has problems.
1) Can sometimes be one hex out due to way works
2) If diffrent setting on map say normal vs arid terrain is wrong colour. I know its only cosmetic but still. Have you found a way to make the terrain change?
Any tips welcome as you said always learning.
Old Woods / Jungle tip as in not vehicle friendly. Can't do without slowing infantry to 1 hex move but if place mud or rough vehicle slow & high bog on mud. If place these woods using autumn so red & a hex or 2 surrounding less dense using summer green makes obvious which are heavy going & which normal.
Also a point on places with a reasonable amount of pavement makes tanks very fluid as low MP means can combat move further as in still fairly acurate fire, nasty.
