First of all a picture to illustrate the problem.
this fits but its floating in mid air since the center of the tower is in mid air following the lowest blocks.
it would be nice if you could have to the center of the building follow the shape of the building. Instead of lowest block.
hope this make sense i guess its really a matter of how templates are saved. But it would be nice if you could cut parts of a template away and make it fit, without everything being level at center point…i guess it really need to be the whole shape of the template.
Else arches will be a problem and building over ditches…alternative a key to lower and raise templates might just be the easy solution.
