ideYAPI / ideCAD

Don't things go as you planned?

ideCAD® Structural, which is a general analysis, design and drawing program, where steel, reinforced concrete and composite structures can be modeled together in the same platform. Calculations can be made with rigid diaphragm, partially rigid diaphragm or without rigid diaphragm on floors. Multi-storey buildings, industrial buildings and random structures can be modelled according to the rules specified in the earthquake regulations. The truss are integrated in the same system with shell elements that can be used. Thanks to integration, slabs, shearwalls, foundations and truss elements can be analyzed and designed in the same system.

Building Information Modelling (BIM)

BIM is not a stand-alone program. BIM is a process that by working together with architects, civil engineers, mechanical engineers, electrical engineers and other disciplines, preparing the 3D model of the building to include the characteristics of the materials and materials to be used during the design phase and reducing the time and material losses that will occur during the construction. In summary, it is the name of the process that enables analysis such as energy efficiency before starting project. In this process, ideCAD provides full automation in architectural and static project.

Architectural, Reinforced Concrete and Steel Structure Design

With ideCAD Yapı, reinforced concrete and steel mixed multi-storey structures, hall-type and industrial structures, canopy structures, stadium and similar structures, multi-storey reinforced concrete structures with steel-fitting roof can be modeled.


Owing to Building Information Modeling, common data is studied in the architectural and static project design process. In the system that enables architects and engineers to work together on the same structure. The project is modeled once and "Full Integration" is provided. Architectural plan and formwork plan are two different modes of operation within the same project and overlap exactly.

Architectural and Structural Integration
There is no need to re-model architectural projects prepared with ideCAD Architecture for static reinforced concrete calculations. Because the Building Information Model is created in the architectural project phase. Building objects such as walls, columns, beams, foundations, stairs, floors are common for both professions. In addition, the properties of the objects such as width, height, and material are the same. In this way, the engineer receives a project from the architect consisting of elements whose parameters are determined almost entirely at the end of the design work. Defining the walls and floors during the architectural project phase allows the project to start engineering without any loss of information and time and shortens the static project process.

In addition to sharing the three-dimensional building information model of projects with other BIM programs with the help of IFC data, the program allows to read and save in 100% AutoCAD compatible DWG format, and 2D architectural drawings can be imported and used as a base. Data exchange is provided with DXF, DWF, OBJ, BMP, JPG, TIF, TIFF, PNG and TGA formats. With PDF compatibility, projects can be examined "without having the program".

By transferring data to SAP2000®, ideCAD allows comparison of the analysis results of structural systems. Projects can also be transferred to Tekla.
