Only via DMIS. This requires that LK-DMIS either be true DMIS (which I suspect it has more capabilities than are defined under the standard) or have a DMIS translator (which of course can only translate those capabilities actually covered by the standard). Many CMM packages offered the DMIS translator as an option. PC-DMIS has a DMIS translator standard, which supports all versions of true DMIS (version 2.0 and higher).

The only other option is to post out your LK program to XYZ data, and import this into PC-DMIS as a "CAD" model.
