Description

Technical Field

[0001] This invention relates to the field of BIM 3D factory design software technology, and in particular to a method and system for automatically creating equipment insulation models using 3D factory design software. Background Technology

[0002] With the continuous development of digital design technology, BIM 3D factory design software is becoming increasingly popular and has become an essential design software for engineering companies and large design institutes.

[0003] Many engineering companies and design institutes are using 3D plant design software for 3D piping design, but most of these software programs do not yet have the ability to create equipment insulation models and calculate the quantity of insulation model materials. Without the ability to create equipment insulation models, collision checks cannot be performed accurately, and the quantity of equipment insulation materials is calculated manually one by one, which results in large errors and low efficiency.

[0004] To overcome this deficiency and improve design efficiency and model quality, a method for automatically creating equipment insulation models using 3D plant design software has been developed. Summary of the Invention

[0005] To address the technical problems raised in the background, this invention provides a method and system for automatically creating equipment insulation models using 3D factory design software, solving the problems of calculating the insulation model and materials of existing BIM 3D factory software.
