Abstract

The architectural design process requires spatial planning that involves searching for building drawings with similar compositions to the ongoing project. However, the current search methods involve searching for architectural drawings based on a high level of shared similarities in specific details. Spatial elements such as spatial relationships and compositions are vital for design case studies but are complicated search terms for finding similarities in architectural drawings. To extract the spatial relationships in a graph format from a drawing, this research proposes a methodology that utilizes BIM and Dynamo algorithm to detect drawing elements and generate an intersection area that defines the type of drawing based on the adjacency of spatial elements in the drawing. Therefore, the methodology proposed in this paper is a method of building a spatial relationship database that utilizes an algorithm that finds similarities in spatial relationships in existing architectural drawings. It is expected that through this algorithm, architectural design data, which has been qualitatively accumulated so far, can be accumulated in a quantitative form for an automated space planning system that architects can refer to in the spatial planning process.
