For the definition you can use a plane or a pre-defined plane. (Pre-defined planes: RX or RY or RZ). (see CAD-PLN, <a href="CAD_PLN_en.htm">Definition planes</a>) The origin point of the chosen plane is the new coordinate origin. In relation to the design plane are now: - Coordinate data - Displaying positions The display of the mouse position can be relative or absolute. Relative: (Default Setting) the coordinates in the new coordinate system; Absolute: Sets all coordinates to absolute origin relative. Toggle the radio button between "rel" and "abs" next to the display of the mouse position. To reset to the absolute coordinate system - Reset ConstrPlane Example: R20 = P(100 0 0) DR DY # Zero in 100,0,0; new X-axis in 0,10,0 R20 # Enable use of a new coordinate system. See Example model sample_ucs1.gcad <A NAME="F1"></A> <h2>Reset ConstrPlane</h2> Reset to the absolute coordinate system Plane 0 defines the absolute coordinate system. Create with output code "R0" </PRE> </BODY> </HTML>
