I have a client who has asked if I am familiar with a third party software package that will allow him to create custom linetypes to be used in R12. I know this is now available in Release 13, but he needs something now, as his company has put off the purchase of R13 until the second quarter. I checked the Resource Guide, but I couldn't find a description this specific. I've seen packages at shows, but I just can't recall their names. Any Ideas ? Thanks for the assistance.
