Local Coordinate Systems

Local coordinate systems are used with deflection plots to define a deflection plot that is not orthogonal to the global planes.

Local coordinate systems (LCS) simply defines new coordinate directions for the results. The following figure shows an example of using an LCS. The LCS is on an angled wall. The Z-deflection results are displayed and assigned to use the LCS rather than the global system. The LCS does not zero out the results like the first anchor location does.

Use an LCS when the coordinate system used for the analysis does not correspond with how the part warpage must be interpreted. For example, the LCS can be used to define the direction of assembly, so an assembly plane or assembly features can be evaluated.
