This determines from an analysis task the centre of mass principal axes of the particular analysis model. These results are used to generate a new axis set.

This dialog can be accessed from the Model > Model tools > Create new raft model menu command. This command creates a new model from the existing model by taking the geometry and updating it with nodal support stiffnesses based on the soil stiffnesses calculated for the specified raft analysis case.

The information supplied on these pages provides a description of an portal or orthogonal frame, which is subsequently used to generate the structural model. The units of length are reported on the dialog, alongside a sketch of the structural form. This is available from the Model > Coordination tools > Generate 3D orthogonal frame option.

It is possible to create models in GSA which contain multiple structures. This can lead to problems with some of the solvers. This is more likely to be an issue when there are analysis stages as it is then easier to leave parts of the model unconnected. This tool allows a stage to be selected and list created with the elements in the different structures within the model.

Each GSA model has a set of units associated with it. These units are saved along with the data in the GSA file. So when an existing model is opened the default model units will be those saved with the model. When a new model is created the units used for that model are determined by looking at the users preferred units. The base units for a model are changed in the Units specification. This is accessed either from the Units specification. This gives the Units dialog, which allows the user to change the units individually or for standard unit sets to be selected. The standard unit sets are summarised in the table below:
