How many coordinate systems are used in CAM 1 hdes Solution

Solution

There are mainly three coordinate systems in autocad and ZWCAD+: the Cartesian coordinate system CCS, the World coordinate system WCS, and the User coordinate system UCS.
Cartesian coordinate system:
Any points in the space are specified by the 3-dimension coordinate, which also specify the position of the point in the space. You can use the Cartesian coordinate CCS (e.g. picture 1) to signify the position of the point in ZWCAD+. Users execute ZWCAD+ to automatically enter the first quadrant of the CCS (that is , the WCS). We can only see the xoy plane, so only the coordinate value of x and y is constantly changed, while the coordinate value of y is always zero.
World coordinate system:

WCS is a default coordinate system and a basic coordinate system to draw and edit patterns in ZWCAD+. It does not change along with the user’s operation.
