“Surface development” or “surface pattern making” is the process of creating a 2d pattern for any shape that will be formed out of sheet material to create a 3d assembly.
The skills of surface development pattern making are important for decorative sheet metal, historic preservation, metal roofing, and copper work. Learning how to develop a pattern for any shape you would like to create can be useful for larger architectural forms as well.
One of the techniques used in pattern making is called “parallel line development”. This skill is vital for creating notching patterns for standing seam roofs.
