## Can you specify an arc by its length and not by radius?

I need to make an arc between two points and need it to be a specific length

Create two points and fully constrain or fix them. Draw a three point
arc whose ends are coincident with the points. Apply an arc length
dimension (left click the arc, then both end points). Adjust the
dimension to the desired value.

If you click the two endpoints and the arc itself, you will get an
arclength dim.

Sure, if the endpoints are constrained.

Click the Dimension Tool, click the arc, click one end, click the other
end...edit dimension as req'd.

make a circle of the desired radius, and use the desired length (L) to get
the included angle of the arc -
the included angle is A = 360x(L/(2(pi)r ))  ( I don't have a symbol for pi
on this computer).  You can either draw an arc with the given included
angle, or draw a radius of the circle, rotate it through the angle A and
trim the circle.
