Finding Angle with respect to X axis in VB?

[Simon Teng]

In my VB program, I used the FindStraightEdge function to get a line for a particular edge. I would like to know what is the angle with respect to X axis. In the Measurement Studio, I use the "Caliper" to find this angle; however, in VB the Caliper function doesn't seems to have an option of measuring angle. Am I missing something here???

I found the "FindAngleBetweenLines" function. Is this the only method to measure angle?

Thanks,

Simon,

Probably the easiest way to do it is to create a variable that contains a line going from 0,0 to 1,0 and use the "FindAngleBetweenLines".

Another way is to use the endpoints of the line to calculate its angle relative to horizontal. You can use atan(dy/dx).
