Generate horizontal cross section plots using python

RE: Generate horizontal cross section plots using python

Dear Brian,

One thing to comment, as from your description it is not clear what the failure message is, is to check for which Plots object you try to configure.

The object Plots[-1] always points to the lastly created plot in Output. To give you an example:

When opening a project in Output by default you get the deformed mesh, which is now the Plots[-1]
When creating a cross-section a new plot object is created and you see a different window loaded in Output, so:
Deformed mesh is: Plots[-2] or Plots[0]
Cross-section is: Plots[-1] or Plots[1]
That logic continues, when opening a different project or you create a structureplot, too.

If you cannot figure out why your script does not do what you need, we can further assist you in a service request. Note that as we do not do code reviews in support, we can check the PLAXIS commands and their Python equivalents that work as intended.

I have the same issue. Runs the first cross section plot but fails on sub sequent ones

Thank you, I'm getting a step closer. The goal is to export cross section plots for all phases in my model. In which I preferably also can set the results that are shown in the cross section (e.g. Puz, utot etc.). with the command you provided I only can create one cross section after this it runs into an error. Below the error and the code.

Error:

lxscripting.plx_scripting_exceptions.PlxScriptingError: Unsuccessful command:
The command 'crosssectionplot' is only for 3D model view plots.

g_o.Plots[-1].PhaseBehaviour = 'projectphase'
for phase in g_o.Phases:

phase_name = phase.Name.value #retrieve phase name
phase_id = phase.Identification.value #retrieve phase identification

The correct syntax is:
g_o.crosssectionplot(g_o.Plots[-1], (0, 0, -10), (1, 0, -10), (0 , 1, -10)) # the parentheses for the coordinates are optional

This is because the Plot object and the coordinates are parameters as explained in the Command reference.

Note that we also have a Scripting reference that can be launched via Input and it includes the Output commands, too.

Ah good to know that it is being looked into. Yes I know the command for the cross section, but how does the command look like in Python using the remote scripting server. I think it should look like someing as below but I can not get it to work. Are you able to help?

g_o.Plots[-1].crossectionplot

Dear Klaas,

An example of the command to create a cross-section specified by points (0 0 -10), (1 0 -10) and (0 1 -10) is:
crosssectionplot Plot_1 0 0 -10 1 0 -10 0 1 -10

This command is explained in the Help>Command reference or you can see it generated if you create manually a cross-section in Output using the side toolbar icon.

Note that you have also submitted a service request about this question and it is currently being handled by a support engineer. The number is 7001028158.
