Displacements in the LOCAL coordinate system

[Faycal]

I wanted to see U-X, U-Y and U-Z in the LOCAL coordinate system rather then showing U-X, U-Y and U-Z in the GLOBAL coordinate system.

With a given U-LAT with PHI-LAT (LOCAL) the displacement perpendiculair to a pipeline in the xy-plane in the LOCAL coordinate system can be determined in excel by factorizing these values and then maximazing the values.

A displacement perpendiculair to a pipeline (LOCAL) has more importance in the case where you have two pipelines parallel to each other. The horizontal displacement of the new pipe (LOCAL !) should always be less then the distance between these pipelines. With the icoon 'Show maxima & minima' in a table with U-X, U-Y and U-Z in a LOCAL coordinate system I can see directly if the distance between the pipeline has been exceeded.

In PLE4Win the displacements are shown in the GLOBAL coordinate system. If you have a pipeline like in the image as shown here below (attachment), the U-X, U-Y and U-Z in the LOCAL coordinate system is not the same as the U-X, U-Y and U-Z in the GLOBAL coordinate system.
