element(Real1..Real2)

[compaqdrew]

In the calculator help and also the manual, it mentions a “real value” syntax for the element (“Point on”) function.

In particular

> element(0..5) creates a slider bar with a value of 2.5 initially.

Try as I might, after entering this example into geometry symbolic view I can’t get the bar to appear anywhere (plot view, I guess?). This is unlike the element(Object, Real) syntax, which works just fine.

Any thoughts on what I’m missing?
