Im sure this problem is very easily solved so sorry about this.
Basically on Hammer, when I click to select an object on camera view it selects the object furthest away if that makes sense. For example if there are two walls one infront of the other, if I click with the intention of selecting the front wall it will select the back wall ...
I thought the solution would be to tick or un tick the 'Selection order' box on Options:3D Views but this hasn't worked. Any other solutions please?
