> thanks i was not aware of the set size square command.  that is helpful in some cases, however, it isn't helping my issue.  i have an airfoil shape and the view is distorted unless the xrange and yrange are the same.  in 3d i do use the view equal xyz and that works to keep the propeller blade geometry looking correct.  however, as i mentioned i can't seem to zoom and pan the way i need to view the model good, due to its long aspect ratio.

i made a work around.  i wrote the *.plt entirely in Fortran 77. i just added some code to the one i was using the generate the *.dat file.  this allowed me to scale the axes as needed.  the reason i made this plot was to get around the 3d zoom problem.  so i can now view all the geometry. some in 3d and the rest in 2d. here is some of the code in case anyone is interested.

if you could still consider my requests, they would be most helpful.  this is just a work around given the current state of gnuplot (version 4.6.0).
