This can be done with the following, where Flowfield is the part name. p_ID = ensight.objs.core.PARTS[‘Flowfield’][0].PARTNUMBER Note, the example will throw an exception if ‘Flowfield’ does not exist (the returned ensobjlist would have length of 0 if the part did not exist). It will also avoid the side effect of changing the part selection. If you need part selection as well, then: part = ensight.objs.core.PARTS[‘Flowfield’][0] part.SELECTED = True p_ID = part.PARTNUMBER Should work. This exploits that fact that the PARTS attribute is not a list, but an instance of an ensobjlist, which supports attribute based find operations (via .find(), which includes things like wildcards, etc) and implicit find using a string (or iterator of strings) as the index. It also supports things like: parts = ensight.objs.core.PARTS[[‘Ground’,’Coil’]]
