I'm very new to ansys scripting, so this may be a trivial question, but I couldn't find it asked anywhere else and have hit a roadblock.

Background: I would like to create individual named selections for coplanar holes in a solid body, with the context of the holes being a bolt pattern. I would like the user to only have to specify a radii range and a coordinate range (pick all coplanar holes of a given size).

Currently I have a script (attached) that creates a named selection for all holes (faces) on the body that meet the criteria. I envisioned the following next steps:

• Generate a list of all the face IDs in the named selection I created
• Search for which face IDs share edge IDs (which cylindrical faces are part of the same hole)
• Create a named selection for those two faces that share an edge
  • Do this for all face IDs in the list without repeating 
• Once a named selection has been generated for each hole I would delete the original named selection that included all the holes

I am currently stuck on the second bullet. I can't figure out a way to investigate the edge IDs of a given face ID, and compare those to the edge ID of all other face IDs. Any guidance or feedback on a different approach would be appreciated.

Hi

Faces have a property called Edges – see the workbench and the extension examples ACTExtensionExamples.zip\TraverseExtension.

Before that from the ids in the ns shown, one needs to get the geobody data using those Ids (https://discuss.ansys.com/discussion/435/what-are-the-methods-to-retrieve-geo-bodies-and-tree-bodies),

and then one can use the Edges property to get all edges belonging to that face.

So below is an example on how to get the first face in the list of faces from ns and then the edges belonging to that face (medg called):

mf=ExtAPI.DataModel.GeoData.GeoEntityById(ns.Location.Ids[0])
medg=mf.Edges

For more help I would suggest to post script questions in the dedicated for scripting forum (discuss/ansys)

All the best

Thank you for the prompt reply and clear answer Erik! This is exactly what I was looking for.

I'll be sure to move future script questions to the location you recommended. Would you be able to clarify where I can find that ACTExtensionExamples.zip folder you recommended referencing? I'm not sure how to access this, but would appreciate more examples.

Hi

Great to hear that it helped.

The dedicated for scripting forum (discuss/ansys) is great, and we can post questions there, but it also has many many script examples (we can search in there) that might be of help.

As for the ACTExtensionExamples.zip, we can download it via Workbench, and in the project schematic, below the main menus, there are some toolbar buttons.

Click on the one called ACT Start Page. A new Page will load onto the project schematic. There click under Download Examples on Extension Examples (see here for an image: ACT extension image). 

All the best

Erik

Thank you again for the help Erik.

I have another follow up question. I tried to ask a question over on the developer forum like you suggested, but I cannot find any way to either ask a question on that forum or even engage with other questions via comments. Im not sure if there's some basic functionality im just ignorant of, or if theres a type of profile you need to interact on that forum. Ive attached screenshots of what I see on my end when logged into the forums:

I would like to use the forums like you suggested, but I can't find anyway to interact/engage on the platform at the moment.
