In the LIRA-CAD module, the DWG file import tool is greatly improved. The tool now enables you to generate new objects tailored for the LIRA-CAD module and more precisely modify parameters throughout the import process.

Users praised the previously created technology for importing DWG from a single file. To boost efficiency and convenience, this capability has been substantially enhanced in the latest release.

• Multi-layered drawings for a single storey:
  

  In previous versions, all structural elements were located on one drawing, which occasionally led to crowded data. With the updated version, users can organize the structural components by category and produce many drawings for a single storey. For example:

  • Separate drawing for the pile groups and foundation slab.
  • Separate drawing for columns and walls.
  • Separate drawing for beams and slabs.
• Advantages of the new approach:
  

  This way of entering data makes the process more convenient and reduces the chance of errors. It is simpler to locate and modify the elements you require when they are divided by categories.

• Consistency with familiar design practices:
  

  The new approach is closer to the standard technology of working drawings, where similar elements are displayed on separate sheets. This shortens working time, reduces the risk of errors, and makes the data entry process more intuitive without the need for retraining.

The tool for import of DWG file is greatly modified in the latest version of LIRA-CAD module, providing a number of new and enhanced features. With the help of this innovative tool, the user can generate new objects unique to LIRA-CAD and more precisely modify settings during the import procedure.

Important aspects in the new version:

• Import as a block of underlays: Several floor plans can now be included in a single DWG drawing. In order to accomplish this, specify an elevation or list of elevations for each plan and a base point; the plans will be aligned along the height relative to this point. When the data is imported, several floors are generated, and the plans are placed on top of each other.

• Create new object types: In this version of the program new object types are added, such as main and additional reinforcement in slabs, opening in load, opening in space, thickening in slab and foundation slab, line segment, arc, polyline, and spline. This makes it easy to transform the location of reinforcement in slabs, get drawings in the LIRA-CAD module, and get the reserve factor of a pilot reinforcement (PR).

• Use hatching as a basis to generate the building objects: You can now import hatchings from DWG files, it enables you to generate more complex structural objects, loads, spaces, and other elements of the framework.

• Import 3D polylines: Import of 3D polylines is supported; it enables the user to create objects of complex configuration in the model space.

• Enhanced work with floors: It is now possible to work with each floor independently and define parameters (thickness, section, materials, etc.) for objects on each floor so as to improve flexibility and accuracy of modelling.

• Save settings to templates: New option to save parameters of objects to templates and save the template to a separate file. This option makes it simpler to share a customised preset data with coworkers, reuse settings, and standardise projects.

• Model validation: After the import process and when the framework of the structure is generated, the model is validated for possible errors and inaccuracies that may occur during the generation of the building information model.

The LIRA-CAD model is now much more flexible, accurate, and productive thanks to these upgrades, which also greatly enhance the modelling and import procedures. This leads to better and more effective design of engineering structures.
