POLARDISTANCEX

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

Syntax

POLARDISTANCEX(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
`POLARDISTANCEX(P0,45,[30,30])`	`42.4264`
`POLAR(P0,60,POLARDISTANCEX(P0,60,P2))`	`[500,866.0254]`

Notes

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