CAN I USE POINTCLOUD THIS WAY?

When you are constructing a circle out of the scans, what error are you getting that is not allowing you to construct them together? Are you using the "Select All Hits" button during construction, and in the correct workplane if doing 2D constructions? I only have experience constructing features from a COP from laser scanning, but I don't see why creating a COP and then using it to construct would not be okay. Since it's created out of the same hits. Does your COP hits count add up to the amount 3 circle scans would have?

I know other have given you a good alternative, but actually you Pointcloud hack is perfectly valid and I use this fairly often now for constructions.

Much easier than messing around with .HIT[..] syntax etc and much cleaner code than the 'Select all hits' code which gets generated.

I am going to have to try this out sometime. 

I guess this is one of those times where there is 5 different ways to do the same thing. Thank you to every one who helped out.

Agreed! There's more than one way to exercise the demon 

I have also used the pointcloud function for other tasks outside of what it was designed for!
