My name is Lothar Klein from LKSoft, Germany and I'm involved in the development of the STEP standard ISO 10303 and its implementation. This involves also areas such as CAD, CAD data exchange, PDM, PLM, Printed circuit boards and EDA. In the past I developed ColorCAM and was involved in the development and implementation of EDIF. You can reach me by e-mail.
Because I'm not a native English speaker please apologies if my writing is not as good as it should be.
