I am a product designer for inground pool liners. Our current software system is autocad 2004 with Eastman Pool Design Suite (EPDS). When laying down the patterns for our cutting floor EPDS has some problems with accuracy dealing with coves and side slopes. Are there any programs out there which provide more accuracy? Also, we need to find a way to quickly create standard liners as opposed to re-designing the same liner over and again. Any ideas out there?
