There are a few material controls that would greatly help renderings. The two biggest are the ability to "bend" a material and the ability to set a base point on an object.
I do these renderings for every job now and with a little more control I would be satisfied.
I've attached a couple of examples. These were all completely modeled in ACA and rendered in ACA with a render time of 15 minutes or less. For the time I am very pleased but as you can see the arched soldier courses material's don't bend with the object (and it's way too time consuming to create a material for each radius). You can also see that since I can't control where the soldier courses base points are I get a mortar joint randomly.
