Description
Function HAngle returns the angle of the referenced line or arc object.
FUNCTION HAngle(
h :HANDLE) : REAL;
def vs.HAngle(h): return REAL
Parameters
h HANDLE Handle to object.
Return Value
Remarks
You can use this routines for getting the angle (slope) of a straight wall as well.
It will also detect the eventual reversion of the wall, consistent with the OIP.
On round walls the eventual reversion is NOT detected. Check if the wall is counterclockwise:
IF NOT GetObjectVariableBool(wallH, 570) THEN wallRot := -wallrot;
For rotated rectangle and oval, the angle is in range [-180;180].
Example
VectorScript
PROCEDURE Example; BEGIN CallTool(-202); Message(HAngle(FSActLayer)); END; RUN(Example);
Python
def Example(): vs.CallTool(-202) vs.Message(vs.HAngle(vs.FSActLayer())) Example()
