However, it is more elegant to parameterize the input once and save the model as a block. The block can then be opened and edited via the Block Manager.
However, the nodes and loads must be parameterized accordingly beforehand. The exact procedure can be found in the video. To save the block, the entire structure must be selected beforehand. The block can then be imported directly into RFEM or RSTAB or via the block manager
As you can see in the picture, you only have to enter the span lengths, the height, and the dimensions of the headers. You can also parameterize and consider the loads when inserting the block. After you insert it, the newly created structure is opened in RFEM or RSTAB.
