The options shown are automatically adjusted to fit the space available. When the window is large enough, it looks like below, but if you make the window smaller, the material types and standards dropdowns will disappear.



The material defaults to the first one in the list - but you can edit the order of this list from the materials options window.


The end type options will depend on the material chosen (for example, the Closed and Forged option will only show for a hot coil material), and when you select an end type the default values for dead coils and tip thickness will be entered. You can edit these from the Design Defaults option page.


The end fixation can often be left as "not known". This only affects the buckling calculations, so will not stop you designing your spring.
