FoundationPro
GetProfileElement

Gets a single value from a profile, located at the specified index.

FoundationPro

Gets a single value from a profile, interpolated at any point.

FoundationPro
GetProfileValue

Gets a single value from a profile, located at the specified X (real-world) coordinate.

FoundationPro
