Hi everyone, I am plotting a 3D diagram showing isotherm layers and hypocenter. I have done the plot of hypocenter symbols using psxyz and -Sc. However, the plots are projected in a planar model, and the circles don’t resemble exact circles. Is there a possibility to rotate the symbols to be visually circular in vertical planar? Here is the example of command used: awk ‘{print $8, $9, $10 }’ events | gmt psxyz -B1 -Bz -R -J -JZ -p -Gblue -Sc0.22 -O -K \>\> $ps Also, is there a possibility to change the projection of the coordinates axes label? thanks, Guilherme ![diagram](https://canada1.discourse-cdn.com/flex047/uploads/gmt/original/2X/2/26186cc25fbafb3ac5e8164443e9bd2fb916959f.png) ---

The solution I found is to plot ellipses instead of circles and rotate them: ```auto gmt plot3d … -Se${azimuth}/0.3/$(gmt math -Q 0.3 ${elevation} SIND MUL =) … ``` It’s a little bit too much in my opinion, but I’ve been told that the problem comes from POSTSCRIPT not being able to plot spheres, not GMT itself. > [@Plot3d : what am I doing wrong?](https://flint.soest.hawaii.edu/t/plot3d-what-am-i-doing-wrong/3352/4): > > The (lack of) spheres is a known issue, awaiting for its time (need a PostScript solution) Note that this workaround collapses when azimuth is 0. ---

Thanks for the suggestion. I will try it. Yes, I was feeling a lack of a sphere or another symbol that is not square/rectangle to plot in 3-D, once there is the possibility to plot the whole planet in 3D. ---

An error message is showed when I try to use plot3d: _gmt [ERROR]: Shared GMT module not found: plot3d_ _ERROR: No module named plot3d was found. This could mean one of four cases:_ - 1. There actually is no such module; please check your spelling.\* - 1. You used a modern mode module name while running in GMT classic mode.\* - 1. Module exists in the GMT supplemental library, but the library could not be found.\* - 1. Module exists in a GMT custom library, but none was specified via GMT\_CUSTOM\_LIBS.\* _Shared libraries must be in standard system paths or set via environmental parameter DYLD\_LIBRARY\_PATH._ The same is presented when I try to include other “modern” commands of the GMT, like polar, meca, etc. I am confused because if I just type the command (e.g. gmt meca) it works normally, but not on the code together with other commands. ---

All gmt modern mode scripts start and end with gmt begin gmt end If not it is classic mode
