The attached image shows pentable settings, location, config options and a comparision of what is being seen when exporting a pdf and what is on screen. All pointing to the right place with all pens turned down to 0.001cm!
The PEN Table may not be working as all the pen thicknesses have been set to be the same thickness, the weird thing is that this has worked previously. I wonder if there is some other setting overiding the pentable? I have had that previously when we changed to creo 2 and we had some setting conflicts from our standard settings causing unusual behaviour. .
