Historically, has always been dependent on technological advances is the development of high-rise buildings; One of the remarkable technologies, use of computers for analysis of complex structural systems and its ability to produce construction documents. However, digital tools to help in the design of innovative forms of tall buildings comparable to the achievements. In this paper consists of two parts. First produced in the form of high-rise buildings and innovative design process using digital tools based on parametric design approach will be discussed. That purpose is to determine the variable and function.  And then taking advantage of genetic algorithm and programming environment Grasshopper trying to write a program to create optimal form in terms of direct solar light. To confirm the results, the optimum forms of various parameters are compared with each other using extensions Ladybug. The purpose of this article is merged with digital architecture to achieve optimal forms.
