I have done one 3D map of our house using PIX4D, free trial, way too expensive for me to ever own. The advantage of Pix4D is you can process on your lap top, it worked really well. I tried Drone deploy yesterday but I had SD card issues and but the time I worked it out the light had all but gone. Today I will be mapping my neighbour's house and a large dam behind our property. The only thing with Drone deploy is you cannot stitch the maps together on your pc, it has to be uploaded to their system and they do it for you. I think this limits editing options. The big thing with mapping buildings ect is to make sure you set the height of the drone to enable it to miss trees and power lines that may be in the area, I flew mine above the heighest obsticle and set that height as the minimum within the mission map. It is really easy to use, give it a go! just be sure you keep your eye on your bird and if anything goes wrong just switch to sports or atti mode to gain control.
