The Create panel is used to create geometry. FEBioStudio offers a basic set of mesh generation features; you can create primitive geometries, such as boxes, cylinders, spheres and so on. By activating the Create panel a list of buttons is displayed. By clicking on one of the buttons, the creation parameters appear for a particular primitive. Once you have entered the parameters you can click the Create button to add the primitive to your model. See section ↓ for more details on how to create geometry.
