How can we delete existing parts , and import a new geometry ?

Erik Kostson

Say we have an existing geometry with parts, how can we first delete it and then finally import a new geometry into mechanical?

Erik Kostson

One way is as described below (works in 2023 R2 and 2024 R2):

import os

work_dir = r'D:\myheatfiles\PyAnsys\PyMechanical\demo' ## geometry folder / change as needed

## Import geometry

geometry_file = os.path.join(work_dir,'Valve.scdoc')

geometry_import=ExtAPI.DataModel.Project.Model.GeometryImportGroup[0] # gets the Geometry Import

geopartdel=[] ## parts to be deleted
##Delete existing parts

for assembly in ExtAPI.DataModel.GeoData.Assemblies:
    for part in assembly.Parts:
        for body in part.Bodies:
            geopartdel.Add(body.Part)

Model.DeleteParts(geopartdel)

##Imports new parts

geometry_import.Import(geometry_file)

or without looping (parts):

import os

work_dir = r'D:\demo' 


geometry_file = os.path.join(work_dir,'Valve.scdoc')

geometry_import=ExtAPI.DataModel.Project.Model.GeometryImportGroup[0]


geopartdel=ExtAPI.DataModel.GeoData.Assemblies[0].AllParts

Model.DeleteParts(geopartdel)


geometry_import.Import(geometry_file)
