We present an optimization of an interlaced structure that has as starting geometry a Spanish pattern from the middle age to create freeform surfaces. As well we present an optimization of an interlaced structure that has as starting geometry a combination of two patterns to create single curved surfaces. First, we compare some representation methods to transform flat patterned surfaces into freeform surfaces. We recommend the most appropriate method for different types of surfaces such as: vaults, domes, half spheres, saddles, and ripped surfaces. The intent is to use the method that allows keeping as many equal jigs as possible. Second, as the interlaced structures have the capacity of keeping continuity between two different patterns on one direction, we established a method to divide a surface according to a criterion and we create interlaced structures with different density on each region. The pattern is selected based on the density that better suits the region.
