sounds great but does this work Ubique? but there are other options and methods that work Ubique (every where) my question is does using a laser make it level to were you can not put a crown in? and can you angle it 10% to get a crown in
Here's a thread by Shimmy, who does low slope drainage work,where the laser is critical to getting it done efficiently and at the very precise slope:

As far as I know, you can get a laser system that can do just about anything you can imagine. Shimmy mentioned getting the elevation of the start and end of the ditch, and then you know what you have to work with for slope. That's on the easy end. It would be way more complicated and I'm guessing completely impractical to regrade small driveways with a laser. Tones' buddy looked like he was doing a level, or flat, pad, which is much easier to set up with a laser.
To do grading like that, you're best off with something like a grader, long and with the blade midway between the axles. You can do it with a front loader, or a three point blade, but you're fighting the mechanics of the equipment that way. On the other hand, if the laser is adjusting the blade, then you don't need the length, look at somero laser screeds, only two wheels!
