One of the very best utilities in Envisioneer is Collision. Collision gives added intelligence to objects. As you move an object into a model collision will detect if the object will fit and how to orientate the object. See how this fireplace will adjust its position as I move it around the room. It won’t allow it to insert into a space if it will not fit or if there is just enough space. If you still want to insert that object into that position, simply left click on collision to turn it off and you can freely move the object into position. But now you have control and have to ensure that you don’t collide with other objects. Turn it back on once the object is inserted where you want and it will be ready for your next object. Hope that makes your Envisioneer work, one step easier!
