ObjectARX and rotation

[Christopher Dix]

I am attempting to rotate a set of entities in ObjectARX, and I am having
some difficulties. The code I have written does rotate the entities, but
not at the angle I have indicated. Could someone let me know what I am
doing wrong, or possibly post some sample code to accomplish this?

Thanks,

// Begin code
AcDbEntity* pEntity = NULL;
AcGeMatrix3d matrix;
AcGePoint3d point;
AcGeVector3d vec(0.0, 0.0, 1.0); // Z-axis

PointerArray aEntities;

// Set the base point
point.set( 2.0, 3.0, 0.0 );

//matrix.setToRotation( dAngle, AcGeVector3d::kZAxis, point );
// I thought this line would build the matrix. I also tried
// AcGeVector3d::kZAxis as the axis vector.
matrix.setToRotation( dAngle, vec, point );

// Assume we fill aEntities with a group of entities here
.
.
.

for ( int nIndex = 0; nIndex < aEntities.Size();
nIndex++)
{
pEntity = (AcDbEntity*)aEntities[nIndex];
pEntity->upgradeOpen();
pEntity->transformBy( matrix );
pEntity->close();
}

// End code

Hi,

The angle has to be given in Radian.
Hope this helps.
