Yup, I wasn't even aware that it was possible to inspect the external objects (not related to AutoCAD).
Although the vlax-dump-object function works fine.
And when I import the MSWord library - it only affects on the atoms-family.
For anyone interested, my specs are:
Windows 8.1 Pro
ACAD 2017
MS Office Pro Plus 2013
BTW Does that mean you can inspect any external object like that, so you get everytime all the properties and methods?
