WCS can be moved and the same is true for orientation. We do not see any of its utility other than being a legacy feature. WCS was first introduced with the Unigraphics D2 release. (Kindly write us, if you are interested in knowing other criteria of a CAD test for a MNC.) Datum CSYS helps us to fulfill that criteria. You may be instructed, once you finish your modelling, to move that single point and accordingly move your whole modelвЂќ. Whenever you approach any CAD test for any MNC, the requirement is вЂ“ вЂњTo construct your model with respect to a single point. Same is true when it comes to absolute orientation.Дatum CSYS has its own significance though. Only difference is- absolute CSYS gives you reference with respect to absolute 0,0,0- while datum CSYS may /may not be at absolute 0,0,0.

You can assess Location & orientation of an object with respect to this CSYS too -same to absolute CSYS. Unlike Absolute CSYS, it can be moved from one point to another and its orientation can also be changed. When you open the NX modelling application, you will see a datum CSYS in show mode by default. View triad does that job by giving you orientation (if not the absolute 0,0,0). There is no need to keep Absolute CSYS вЂњONвЂќ all the time. вЂњ View Triad вЂќ in NX is a representation of this system. In NX, you can see this coordinate system by clicking on the drop down arrow of Datum CSYS command. Ultimately, Location & orientation of an object can be measured with respect to this fixed reference which is the Absolute Coordinate System. Thus it gives you a fixed reference in a 3D space. It does not move (from one point to another point). Here we will look into 3 coordinate systems related to NX design.ДЄs the name suggests this coordinate system is absolute. NX Design has 3 coordinate systems while NX CAM has a separate one named as Machine Coordinate System (MCS). What we will look into here is a cartesian coordinate system when it comes to NX design.ДЄ Cartesian coordinate system for a three-dimensional space consists of 3 axes which pass through a common point called origin. There are a number of types of a coordinate system like- Cartesian, polar, cylindrical and others. In geometry, a coordinate system is a system which uses coordinates (e.g.: X/Y/Z Coordinates), to determine the position of a geometric element in a 3D space. Question is- вЂњWhat is a coordinate system?вЂќ A curious mind will first come up with this question when one reads the above title.
