This tab controls the "Transformation" of the RFEM 6 / RSTAB 9 model. The parameters of "Translation" (displacement dX, dY, dZ) and "Rotation" (A1, A2, A3) refer to the origin defined in the Dlubal application, taking into account the wind direction of the relevant load case and the size of the wind tunnel.
The "Scaling" options enable you to change the model size in one or more directions. S1 is the axis in the wind direction, S2 transversal to it, while S3 represents the vertical axis. If you want to scale the model uniformly in all directions, select the "Lock aspect ratio" option.
In a similar way, the "Skewing" parameters enable you to distort the model. K1 is the axis in the wind direction, K2 transversal to it, while K3 represents the vertical axis for rotation.
