We recently noticed in a job that, in the process of scaling a set of points in imperial to metric (using RTS), that the Z-coordinates of the points were not scaled correctly. I've attached a portion of the log file showing the RTS details and the information on two of the points. We performed a rotation of the points at the same time, but that shouldn't have any effect, should it?

This was done using MSCAD 2004 SP3.

Pts to process : 1..251

Basept case : PtNum 13

Using base point : N=968.044488, E=1006.215766, Z=101.412000

Rotation case : 4PtNums 13..44,1007..1006

Using rotation : 0.0125 cw

Shift case : NoShift

Using shift : N=0.000000, E=0.000000, Z=0.000000

Scale case : Values NE=.3048 Z=.3048

Using scale factors : NE=0.304800, Z=0.304800

pt 5, start = (N=985.539097, E=1027.356763, Z=0.000000)

rotated 359.5835 ddd.mmss ccw to (N=985.530431, E=1027.363932, Z=0.000000)

shifted by dN=0.000000, dE=0.000000, dZ=0.000000 to (N=985.530431, E=1027.363932, Z=0.000000)

scale adjustments are based on rotated and shifted positions of points

scalexy=0.304800 scalez=0.304800 to (N=973.374204, E=1012.661727, Z=70.501622)

pt 251, start = (N=815.078423, E=1021.937050, Z=99.964000)

rotated 359.5835 ddd.mmss ccw to (N=815.071992, E=1021.874354, Z=99.964000)

shifted by dN=0.000000, dE=0.000000, dZ=0.000000 to (N=815.071992, E=1021.874354, Z=99.964000)

scale adjustments are based on rotated and shifted positions of points

scalexy=0.304800 scalez=0.304800 to (N=921.418472, E=1010.988503, Z=100.970650)

The resulting Z-values don't make sense. This is the first time that we've noticed this happening, has anyone else run into this?

Thanks,

Chris
