Subtraction Solids.

[Assembly]

currently I am trying to use the subtractsolid tool to subtract one PIO from another PIO.

I have a simple PIO Extrude:

------------

PROCEDURE SetObjectParameter;

Begin;

SetRField(HObject,ObjectName,'FrameWidth',Num2Str(1,FrameWidth));

SetRField(HObject,ObjectName,'FrameDepth',Num2Str(1,FrameDepth));

SetRField(HObject,ObjectName,'ExtrudeStart',Num2Str(1,ExtrudeStart));

SetRField(HObject,ObjectName,'ExtrudeFinish',Num2Str(1,ExtrudeFinish));

ObjectName:='0 ASHFRAMEPIO';

HObject:= CreateCustomObjectN(ObjectName,0,0,0,False);

SetObjectParameter;

------------

Then within Vectorworks I have created a solid box extrusion that intersects the PIO.

By using the Subtract Solids function within vectorworks, I am able to subtract the box from the PIO.

---converting the result to a symbol and exporting as vectorscript allows me to see what process vectorworks uses to carry out this procedure.

--------------

tempHandle2 := CreateCustomObject('0 ASHFRAMEPIO',0,0,#0.0000000000000d);

ResetOrientation3D;

Rotate3D(#0.0000000000000d,#-0.0000000000000d,#0.0000000000000d);

Move3D(-5020.000000000000909,300.000000000000057,0);

Record(LNewObj,'0 ASHFRAMEPIO');

Field(LNewObj,'0 ASHFRAMEPIO','LineLength','1320.000000000000227');

Field(LNewObj,'0 ASHFRAMEPIO','FrameWidth','45');

Field(LNewObj,'0 ASHFRAMEPIO','FrameDepth','90');

Field(LNewObj,'0 ASHFRAMEPIO','WallH','2400');

Field(LNewObj,'0 ASHFRAMEPIO','Spacing','450');

Field(LNewObj,'0 ASHFRAMEPIO','TopPlateFalls','0');

Field(LNewObj,'0 ASHFRAMEPIO','DwangSpacing','800');

BeginXtrd(0,1560.000000000000455);

Rect(-4280.000000000000909,900.000000000000227,-3120.000000000000909,-440.000000000000114);

EndXtrd;

ResetOrientation3D;

Rotate3D(#-0.0000000000000d,#0.0000000000000d,#-0.0000000000000d);

Move3D(0,0,240.000000000000057);

tempHandle1 := LObject;

tempHandle := PrevObj(tempHandle1);

result := SubtractSolid(tempHandle, tempHandle1, tempHandle2);

ResetOrientation3D;

Rotate3D(#0.0000000000000d,#-0.0000000000000d,#0.0000000000000d);

Move3D(4360.000000000000909,-345.000000000000057,-1155.000000000000227);

My problem is, by simply copying this code to a new vectorscript, the result from the subtraction process returns -20- (meaning a bad input).

---Is there a way through script, to subtractsolid from PIO's? I would like to end up subtracting one PIO from another PIO.
