summary 
In this paper, we introduce the Nip and Tuck Method, which provides a general approach to construct complicated shapes without using highlevel software and/or without solving complex mathematical problems. Our framework is based on discrete version of GaussBonnet theorem, which states that the sum of vertex angle defect in a given piecewise planar manifold or manifold with boundary mesh surface is independent of the number of vertices, faces and edges. Based on this property, architects and designers can simply introduce negative and positive curvatures in the places they want to obtain desired shapes. We presented Nip and Tuck Architecture to freshman students in beginning level design studios to design arches with modular elements along with other methods. Several groups of students, that chose to use Nip and Tuck approach to obtain individual modules, were able to design and construct unusual smallscale arches.
