POLARDISTANCEY

How far along an angled line from one point you go to be level with another (the same Y).

Syntax

POLARDISTANCEY(p,angle,q)

Argument	Meaning
p	The position the line starts at.
angle	The line's angle, in degrees.
q	The position to be in line with.

Result

A distance along the line.

Examples

In the example drawing:

Expression	Gives
`POLARDISTANCEY(P0,45,[30,30])`	`42.4264`
`POLAR(P0,60,POLARDISTANCEY(P0,60,P2))`	`[173.2051,300]`

Notes

The Angle snap mode writes it when the new point lines up with another (the same Y). A line that never gets there (straight across) gives the largest distance it allows.
