How to check Angle (direction) of Dimension


DomC

Recommended Posts

Dimension Direction.vwx

Hello
I am able to check if a Dimension is vertical or horizontal with 

direction = vs.GetObjectVariableReal(dim,value)

On my mac version, it returns 0 for horizontal and 1.0 or -1.0 for vertical Dimensions. Unfortunately this seems not to work on Windows. There is always 0.0.
I could test if xDiff is bigger than yDiff (of the Dimension Points) an decide it is horizontal but this can result in errors with some dimensions.

Anyone has an Idea to get that information reliable?

Hi Dom,

 

Try this:


Procedure T;
VAR
    h1 : HANDLE;
    b1, b2, b3 : BOOLEAN;
    i1 : INTEGER;
    r1, rAngle : REAL;
BEGIN
    h1 := FIn3D(FSActLayer);
    REPEAT
        IF (GetType(h1) = 2) THEN BEGIN 
            GetMarker(h1, b2, b3, i1, r1);
            IF b2 | b3 THEN BEGIN
                b1 := True;
                rAngle := HAngle(h1);
            END;
        END;
        h1 := NextObj(h1);
    UNTIL (h1 = Nil) | b1; 
    Message('Angle is: ', rAngle);
END;
Run(T);

Even better as a function:

 

Function GetDimAngle(h1 : HANDLE) : REAL;
VAR
    h2 : HANDLE;
    i1 : INTEGER;
    r1 : REAL;
    b1, b2, b3 : BOOLEAN;
BEGIN
    h2 := FIn3D(h1);
    REPEAT
        IF (GetType(h2) = 2) THEN BEGIN 
            GetMarker(h2, b2, b3, i1, r1);
            IF b2 | b3 THEN BEGIN
                b1 := True;
                GetDimAngle := HAngle(h2);
            END;
        END;
        h2 := NextObj(h2);
    UNTIL (h2 = Nil) | b1;
END;

Fantastic Julian this is a very reliable solution, Thank you. I implemented this way:
 

dim = vs.FSActLayer()

def GetDimAngle(h1):
    h2 = vs.FIn3D(h1)
    DimAngle = 0
    while h2 != vs.Handle(0):
        if vs.GetTypeN(h2) == 2:
            BOOLEAN, style, angle, size, width, thicknessBasis, thickness, visibility = vs.GetObjBeginningMarker(h2)
            if style:
                DimAngle =  round(vs.HAngle(h2),0)
        h2 = vs.NextObj(h2)
    return DimAngle 

DimAngle = GetDimAngle(dim)
vs.AlrtDialog(str(DimAngle))
