Hi EB, Can anybody tell me how to rotate a plane by some angle in AutoCAD (R14 or 2k). I want to develop a program which will rotate the object as per the angle from a perticular axis and angle from perticular plane. (e.g. 50 deg. from X axis and 45 deg. from XY plane) For this I can rotate the UCS by the angle made with a perticulae axis and draw the object. But how can I rotate the plane for the later part ? Any help regarding this will be very much appriciated. Thanks in advance, ~b.
