We invite you to check out our video on the integration of Tekla Structures models with SP LIRA 10.12. Data exchange of a wide range is possible both thanks to the plugin and the publicly available IFC format. Using a simple model as an example, we tried to demonstrate in this video the basic steps for building a spatial scheme in Tekla, creating loads, transferring the model for the selection of steel cross sections in SP LIRA 10.12, and assigning the selected sections. The main principles of interaction between the two programs through the IFC format are also mentioned. The video is recorded in Ukrainian.
