Further improvements related to the generation and modification of model

  • The mirror copy command is improved, taking into account the correct location of the cross-section in the elements and the boundary conditions assigned to them.

  • The soil model now has a new option that allows it to be temporarily disabled during calculations. It is not required to exclude the soil model from the project in order to identify the best possible design options. Instead, you could activate an option that will ignore the soil model in calculations. This offers a more practical and adaptable method of using the soil model.

  • A number of new features are developed in the "Layers" dialog box:
    • for more convenient work, layers may be automatically organized by name;
    • when the underlays are imported, the colours of the layers used in the DWG file fully correspond to the colours in LIRA-CAD module;
    • to check that the layers belong to certain objects, a special graphical view "Layer Colours" is developed.
  • We have changed how the parameter value for the DH is interpreted in response to many requests from our users. This tool's original purpose was to simulate niches and recesses. That is why the "Depth" parameter was made for it in the interface. The deeper the niche, the higher the parameter value. Many users have discovered an additional application for this tool, though. It was possible to represent pedestals for columns, local thickenings in slabs, and capitals by specifying negative depth values. It's challenging to classify these components as niches. Consequently, the DH was introduced instead of the term "Niche," which frequently received a negative depth value.

    Since a positive sign is associated with an increase in thickness and a negative sign - vice versa, it was decided to name the parameter "Thickening" and interpret it accordingly. Now, at negative values of this parameter, the thickness of the slab decreases and accordingly, a niche is formed. At positive values - a local thickening of the slab element is formed.

  • In the design of buildings, there is the practice of placing elements at intermediate elevations located between the main levels of the building. To facilitate the work with such objects at certain heights, there is a tool to create "intermediate levels". In the new version of the software, in the "Project Structure" dialog box for such objects, you will see indicators of height elevations, thus facilitating the management of structures placed at different height elevations.

  • To facilitate the work process, the key tolerance settings required for the project are now gathered in the project properties window. These tolerance settings are important at various stages of the program: they are used for model generation, during the import of external models, during the design of panel buildings, and when the complete model is checked for errors and warnings. The design process is more standardised and predictable when these characteristics are all in one location, which reduces errors and speeds up the design process.

  • The key tolerance settings required for the project are presented in the project properties window. These properties are used in a number of cases:

    • for model generation;
    • when importing models;
    • in the construction of panel buildings;
    • for validation of the generated model.
  • The "Shaft" tool is improved. New functionalities:

    • check points are added at the top of the object to make it easier to resize the shaft;
    • for more convenient and accurate generation it is now possible to display the shaft in the analytical presentation of the model;
    • in the "Editable Analytics" mode, the option to change the shaft size is now available;
    • for the shaft element, the "Extract properties" tool is improved and applied; it allows you to copy properties and apply them to other created objects.
