Re: Still help about the field? Hello; If you have a dwg file in 3, you can import the project and define only the sections and joints of the elements. If there is a 2d dwg file, you can import it to use it as a guide line. In the modeling phase, enter the vertical elements with the steel column, the horizontal and cross elements with the steel beam command. Since the system you will apply will be a space lattice system, you must create the appropriate conditions in the freedoms section of the properties of the elements. Good work.
