Mike,
Here are a few things to consider, but might not be what you want to hear.
Some have already mentioned using Adobe Illustrator to open/import a PDF and then export a DXF to use in Pro/E. I would try this out before making plans to use this as a fix for all your cases. I say this because I have worked the other direction of exporting a DXF or PDF in Pro/E and open it up to use in Illustrator and it can be a mess due to the export creating hundreds or thousands of small segments for lines and curves. Thus if needed in Illustrator for creating artwork or other reasons I have usually used the imported file as a template and then recreated the lines art in Illustrator. Some simple things do work like times I have exported a rectangle to size to give to a designer for them to create artwork like a product name or logo. Modifying the small segments can be rather time consuming, but depending on what is desired in the end sometimes better to recreate than dealing with tons of small entities that are not tied together. I'm not saying it
won't work, but try it out first.
My question is you do not need to use the associated part anymore and just need a changed drawing? If the part is used in your models/assemblies I would bite the bullet and remodel and recreate the detail drawing. I realize that takes time, but depending on the complexity and usage could be worth it or not.
If you really need to take a short cut I would find a way to modify the raster file in Adobe Photoshop (maybe a light version) or some other less expensive program to make your changes and then import in the raster file if possible. I see where that is possible in drawings, but have had problems with that in the past so not sure how that works or not and especially if trying to make a truly scaled drawing.
If I have the time and resources I would remodel the part in Pro/E and redetail not knowing your specific needs and constraints. Good luck finding other software and or methods to import and change in Pro/E and if you do find a good solution please repost because many of us would be interested in the software and methods.
Good Luck,
