Coordinate Systems
With pCon.planner, planning is possible in both two and three dimensions. The software provides a fixed system of coordinates (known as WCS, World Coordinate System) and a variable one (known as UCS, User Coordinate System). Both of these serve to position objects. The UCS is particularly suitable for aligning objects with each other.

The origin of the coordinate system is depicted in your drawing as the intersection of the three axes (X, Y and Z achsis). Upper left image: origin of coordinate system in Perspective view. Lower left image: origin of coordinate system in Front view. |

Each time the pCon.planner is started, you will first be working in the WCS. Neither origin nor orientation is susceptible of alteration. The WCS is for basic orientation and is always important if you want to return to the original state from a changed rotation and position.
You can insert the UCS into any point in your design and alter its orientation. This makes the positioning of objects particularly flexible.The section Align Objects Using a Reference Point has more details on the use of UCS for orienting objects. While you are working with the UCS, the WCS is kept as the reference system. The UCS reverts to WCS if the Set WCS Origin command is selected from the context menu.
An object coordinates system is a reference system associated with the object and it describes the alignment of the object. This can be used, for instance, when moving or scaling objects with a slanting orientation.
The following section will tell you more about the origin of the various co-ordinate systems, called the reference point, and the operations available for it.
