Integration of information models between different software systems is an urgent task. There are a large number of CAD systems that cover more than 90% of the design tasks, but the mechanism for transferring information between these programs has not yet been worked out. Despite the use of common data integration formats (such as IFC, XML, DXF, DWG, PDF), CAD model elements are represented using various indicators and characteristics. This leads to a partial loss of information on objects. Integration of the model in an incomplete form and filling in the missing parameters manually takes a lot of time and is not effective. To solve this problem, research was carried out, the result of which was the generalization and structuring of the parameters of the elements of information models of building objects. This allows you to solve the problem of heterogeneity of information about the model coming from different sources. Cite this Article: Kateryna I. Kyivska, Svitlana V. Tsiutsiura, Mikola I.

Hots, a Study of the Figure.3 Types of elements in the format of presentation of modelsDepending on the format of the presentation of the model, the elements will have a different set of parameters. So, for the 2D model, graphical parameters (coordinates, dimensions) are relevant, for 3D+ models -physical parameters of the constructive elements (material, section, mass, level of location, load on the element, mode of interaction with other elements: node connection, hinge connection, hard connection, and their means of processing: trimming, crossing, reaching, etc.), for the calculation model, the parameters of finite elements and nodes (boundary conditions, estimated coefficients, etc.).
