The square-to-square frustum is probably the most common sheet metal transformation. There are many applications: boxes, trays, moulds, hoppers, skips,etc. Trays and skips are very often tapered to allow for stacking and moulds for concrete lintels or fence posts are all slightly tapered to aid release. If you're in the welding and fabrication industry then you've, probably already, made a 1000 hoppers because they are used absolutely everywhere. There are many occasions when you can weld all 4 corners and the full pattern development is not always required which means you don't really need this software. When the square-to-square is oblique it can be difficult to visualize, and this is when the software comes in handy. Give the software a go to see if it's of any use to you. Like with all Ty Harness Sheet Metal applications, it's all about the speed of draughting. No one minds spending time on the initial design but the design revisions are lengthy, painful and costly so this tool really benefits the draughtsman when the engineer revises the elevation height for the fourth time in a week.
