Face picking on mouse click

[Indrajeetrt]

Hello,
I am woking on one of the project where i need to pick the surface and create named selection or extrude. Is there any feasibility for the same using ansys geometry core ?

Thank you in advance

You might want to have a look at https://geometry.docs.pyansys.com/version/stable/examples/01_getting_started/05_plotter_picker.html#Select-objects-interactively

This example shows how to enable interactive picking on the GeometryPlotter.

It is only picking the whole geometry not the surface or edge

Can you share your code?

Here is my code i want to pick the face or edge from the plotter on mouser click and return index of the face to extrude the face.
import os
from ansys.geometry.core import launch_modeler_with_spaceclaim
from ansys.geometry.core.plotting import GeometryPlotter
from ansys.geometry.core.designer.face import Face
#%%|

Read .stp/.x_t file

fileName = r"demo.x_t"
#%%
#Lunch modeler with spaceclaim and
modeler = launch_modeler_with_spaceclaim(hidden=True, product_version=241)
geom = modeler.open_file(fileName, True)
#%%

Plotter for geometry

plotter = GeometryPlotter(allow_picking=True)
#%%
picked_list = plotter.show(geom)
print(picked_list)

Hi @Indrajeetrt - so I did some research and there is definitely a bug in some of our functionalities... I am really sorry for that. We will work actively on making it easier to select faces and edges.

Nonetheless, a quick workaround for selecting faces would be to pass in the list of faces of your geometries to the plotter. So, imagine geom was a Body object --> plotter.show(geom.faces) would allow you to select faces individually.
