How can I read a legend settings from a file from a script?

GabrielArias

I have saved many Legends settings in xml files. I can access them interactively using the "Manage Named Legends" RMC on the results legend -> Named Legends -> Manage -> Import

Also once the legends settings are loaded. How do I pick one from the list in my mechanical script?

Thanks a lot

@GabrielArias, I agree. @sachinverghese and @Pierre Thieffry, here is an example where Mechanical scripting users still need to rely on Jscript.

Hi @GabrielArias . This post should help: https://discuss.ansys.com/discussion/513/working-with-legends-in-mechanical-scripting

Thanks @Pernelle, I've read your article before, I've used it to customise my legends, but one thing I cannot control is the addition of the independent bands, either top, bottom or both. It seems that the object does not have the IndependentBands property. The problem, not having this, is that when the settings are copied from a legend (MakeCopy) with independent bands to a new one (Copyto), the new legend looks different as the independent bands are not applied. The workaround I've found is to save the legend in a xm files (manage named legends tool) and then assign it to the new result.

Not sure if there is a way to control the independent bands from the script, if there is it would be much appreciated if you can tell me how to access it.

Thanks again for you help

Thanks a lot Landon, this is what I need, it is bit cumbersome, but it does the job. It would be nice to have a more direct way of implementing this in Python without calling jscripts, but happy with the results.

@Landon Mitchell Kanner in 2023R2, Legend attribute has been removed from GfxUtility:

Do you have a suggestion for more recent versions ?

Landon Mitchell Kanner

@Pernelle Marone-Hitz I have updated to remove the dependency on InternalObject. Please let me know if it is working.

Pernelle Marone-Hitz

@Landon Mitchell Kanner , thanks, this works.

Which module contains "ExtAPI"?

What is the module that contains ExtAPI?

Landon Mitchell Kanner

ExtAPI is already available in Mechanical Scripting. Outside of Mechanical Scripting, see:
