I have been using CorelDRAW to PDF's with vector information to DWG's. It is not something I do often so it was fine. I got a few more PDF drawings and decided to try the converters available. These are the trial versions, but the output seems to be worse than what I get with Corel. Is there any one in particular that gives excellent conversions. I can see spending $200 plus to get what I already get wit Corel. The only time it has given me problems is when I had any kind of bit map scan as part of the sheet. If it was too much bit map data it would take a really long time or freeze up. Pressure tanks Oil processing & storage equip. Steel mill equip. Telecom towers & equip. Wind turbine towers Power plant structures Structural and miscellaneous steel etc. The only time it has given me problems is when I had any kind of bit map scan as part of the sheet.

From doing site layouts with proposed updates, additions and renovations to be budgeted and submitted for bid, to updating and changing existing drawings to reflect maintenance and repair/revision work done on site. I use GSVIEW with PStoEdit and convert to DXF. So far as long as the PDF was a vector the results are pretty good. Other than that I just insert and trace over. i agree with SLW210 i jsut insert and trace over making sure it is to scale, not worth the hassle of converting when for example if there is a dashed line you get a little line for every dash, you still have to trace over it anyway so why bother converting just insert it works pretty good i do it all the time and am only out by maybe 5-10mm when we get the actual DWG files from clients,etc. I've used this one on vector PDF's and was satisfied with the results. This one doesn't have a time limit on the trial, rather a limit on how many drawings can be converted (30), which works well if you don't need to convert PDF's very often. Source.
