The files were sent from company to give use access to all blueprints of gears etc. Some are DXF files and some are TIF files, but most are PRT files. We are a small company and I am in the quality control dept. So you are saying we need to invest in CAD program to open these? Is there not another way to access these files without the expense of this program?
I agree with IRstuff that you should ask the company that sent you the files about what program they used to create them. Some files have a free viewer program, assuming that all you need is to view them. If not, then get the company to send them in a format that you CAN read.
It's possible that there might be a lower cost format converter, but those are sometimes a dubious proposition. You should go back to the supplier and ask for all DXF files.
Thanks for the info. I will talk to supervisor and relay the messege that he might contact supplier of CD and see if they can re-send with appropiate files that we may be able to view. Thank you all for you input.
