    What technique are you guys using to get a perfect match on a radius.
    Something like this:

    No one has a method of creating two perfect radius's on the end of a paver walkway?

    The CAD drawing is just an example of what I'm talking about.

    yes. We have a method!

    I use an old design program for designing our jobs. It's called 'Planscape'. Very old, 100% accurate, and very easy to use.

    Ths first thing you need is fixed points to measure off of. These fixed points must be shown on your design to scale with your design.

    My program will mark the center of a radius if you allow it to. Once I know the center, I can then have the program show how far the center is from the fixed objects.

    yep, we have a method.

    LOL - i thought thats what you meant

    I dunno bout others, but I have always wondered how on earth others do it accurately without a scaled plan with the measurements shown.

    Find a reference point the same distance off the bottom of the walkway and the middle of the walkway. Then hammer a piece of rebar. Then find what distance will give you the radii you want with a tape measure or string. Duplicate on the other side.... I think that only works if you are going for a 90 degree total turn. I think this is a way you can do it.

    Kootoomootoo...how much did you pay for that "special" tool. Does the rebar, string, and marker come in a kit?

    perhaps techo sells it in there overpriced tools?

    Even if you weren't doing a 90 degree you could still use the same method, just measure say 48 inches from the driveway and 96 inches from the sidewalk. Then pound your rebar in and make your curve.
