Thank you, I already have the Bosch measurer, which I can use on a pole, but cannot read or press the buttons 4m away.

Estate Agents use these.

Thanks for the feedback. I can triangulate and use trig, but there has to be a simpler way . The setup time for a 3D measuring device is huge and I can hire one for $125/day. I'd settle for a ruler on a stick .

In most cases I have the original construction plans, unfortunately the dimensions aren't always as stated. The Bosch laser measuring device I have will measure within 2mm, provided that I can hold it steady, see the laser spot and press the button, not easy when you're 4-6m away.

Thank you SolarEagle, (good answer) I'll follow that up. Tony

You could use a plumb bob and use your pole to hold the cord at the upper measuring point, mark the point on the ground and measure the 2 ground points.

Or the laser type, from the ground, pointed vertically to your measuring point. Then just measure the points on the ground.

Or, even now, there's an app for that;

Thanks AussieBob I downloaded the app, but the instructions are vague. Tony

Don't you have the buildings blueprint?

We are required to check measure before we install, most times it's right, but if it's wrong we are responsible. Tony

Thank you, that's worth developing with interchangeable arms. Tony

Measure the shadows at noon, or whenever the sun is squarely over the roof. A little math will correct any errors. Get a standard from the beams that are lined up with the windows, that line goes all the way down...
