The
Curve
Radius is the distance from the curve surface (Red) to the centre of the circle it forms. The smaller the radius, the tighter the curve.
The
Sweep Angle
determines the 'length' of the curve, and is the section of the circle that forms the curve.
Roof Angle + Sweep Angle must not exceed 90 °. Check
Radius ~ Sweep
to show the radius lines to centre and sweep angle.

If you're cutting blocks, concrete, stone or
ANYTHING
and there's
DUST - DON'T TAKE THE RISK
Don't cut it, or cut it wet so there's
NO DUST
-
Silicosis Sucks
And if you're cutting wet, wear a mask - there's dust in the spray mist too!

What do we think? - They're 2 different things:
A
Meter
is a device to measure things - like a Volt Meter or a Parking Meter
A
Metre
is about 3'-3~3/8"
Although diameter and perimeter as measurements - don't seem to fit very well
If the U.S. ever goes Metric, you'll be able to use a Meter to measure Meters - A Meter Meter
(And when we go
back to the moon
to Mars, this time, let's go Metric, ay?)
GO Artemis II !! (thats 2, not eleven - and Artemis is Metric, not Imperial, no matter what they say)
