Hello Michael:

Many thanks for this. The culprit is attached.

It may help to know that this drawing, originally a CAD drawing, was opened in CorelDraw and cleaned up, i.e. to give it smoother curves. It was then saved as a dwg file and that is what I opened.

It might help to explain in some detail why there is an interest in MoI in the first place, i.e. how we plan to use it in our business. What we are really trying to ultimately understand is what is the best work flow. Maybe later, but first things first.

Many thanks again

Andrew
