Force Plug-in to draw independent of the current view.

[steelydev]

I have a plug-in point object defined in the Plug-in Manager.  It correctly draws the geometry I want (tapered pipe or tube) ONLY if i'm in top view or top/plan view.  If I change the Obj Info in any other view, I believe it is updating the geometry relative to my view instead of relative to layer plane.   Can't seem to locate the correct commands to tell the script to draw relative to the layer plane.

 

Any help would be appreciated and happy holidays!!!

 

ROCEDURE TaperedPipe;
VAR
    circle1, circle2, loftSurface, loftGroup : HANDLE;
    
BEGIN
    PushAttrs;
 
    SetWorkingPlane(0, 0, 0, 0, 0, 0);
    

    Oval(-PbottomDiameter/2, -PbottomDiameter/2, PbottomDiameter/2, PbottomDiameter/2);
    circle1 := LNewObj;
    Oval(-PtopDiameter/2, -PtopDiameter/2, PtopDiameter/2, PtopDiameter/2);
    circle2 := LNewObj;

    { Now group the selected objects }
    BeginGroup;
        circle1 := ConvertToNURBS(circle1, FALSE);
		circle2 := ConvertToNURBS(circle2, FALSE);
		Move3DObj(circle2, 0, 0, Pheight);
    EndGroup;
    loftGroup := LNewObj;
    
    { Create loft and shell }
    loftSurface := CreateLoftSurfaces(loftGroup, false, false, false);
    DelObject(loftGroup);
    
    IF (Ptube) THEN 
        loftSurface := CreateShell(loftSurface, Pthickness)
    ELSE 
        loftSurface := CreateShell(loftSurface, -Pthickness);
        
    PopAttrs;
	ResetOrientation3D;
END;
RUN(TaperedPipe);

SetObjectVariableBoolean(1160,HANDLE,FALSE) will set an object to the Layer Plane and SetObjectVariableBoolean(1160,HANDLE,TRUE) will set it to the Screen Plane.

@C. Andrew Dunning Did you forget the Index? Or am I missing something? Your scripts above don't compile or run for me.

Yup.  Edited.

@C. Andrew Dunning That did it.  Thank you!  Just to be clear, it is 

SetObjectVariableBoolean(HANDLE,1160,FALSE)

Done on each of circle1 and circle2.

 

 

Please see below for the entire plug-in if you find it useful...
