Abstract: BIM technology penetration rate is much lower than the promotion efforts in our country,
one of the main reasons is BIM model with large amounts of data are too demanding on computers.
To solve this problem and make BIM model increasingly universal. By using the Revit API to achieve
quadratic development and using the grid model simplification algorithm, the two aspect of the BIM
models are quantized separately. Reduce the hardware requirements and make the BIM lifecycle
model more universal. This has a great significance for BIM development in China. The result shows
that this method can achieve the simplification method of BIM without affecting the use on the
operation and maintenance stage.
