Use of computer programming for the development of a CAD-CAE system on the Revit platform applied in urban drainage projects

Abstract

Urban storm drainage emerged with the evolution of society in search of improvements in health and comfort going through different phases and today it connects with a sustainable and technological bias. Through Python programming, it is possible to integrate a Computer Aided Design/Computer Aided Engineering (CAD/CAE) system into the Revit platform using the Dynamo tool as an intermediary. This work presents the development and validation of a computational tool for dimensioning urban drainage coupled to the graphical project modeling platform Revit. The results obtained with the numerical code point to a good agreement when compared with those generated by conventional tools, using a calculator and an Excel spreadsheet. It shows that, due to the direct and automatic communication between drawing and dimensioning is possible to reduce the time spent filling out spreadsheets and facilitate analyses such as minimum inclinations of the pipe through warnings and factors such as the ratio of the water sheet and diameter through color scales.
