to edit the design parameters. The user icon 
indicates that a custom value has been specified.Use the Defaults form to check and modify parameters of an active design. By editing this form you can make certain parameters default, so that they are applied to your design even after you optimize your design again.
You can click the calculator icon to edit the design parameters. The user icon indicates that a custom value has been specified.
The following design default parameters are available:

Show Solutions Filter before Optimization - Select to always display the Solutions Filter dialog at the beginning of the optimization process.
Design Type - This combo box is unavailable; it displays Generic (AC-DC) or LED (AC-DC) depending on the design family.
Surface-Mount Device Preferable – Select to use SMT components from distributors as much as possible. In event that SMT component is not available or is out of stock a through-hole component may be returned.
PCB Copper Thickness - You can change the default thickness of the PCB copper layer by selecting another value from the list.
Default Component Set - Select the component set you want to PI Expert to use when creating and optimizing the design. This setting changes the default component set used only for this design. You can change the component set to be used for all designs using the Design Defaults Preferences dialog. See Custom Component Library Overview and Custom Component Set for detailed information on the component library and the use of component sets.
Default Core Material - You can change the default core material that is to be used in the transformer documentation PI Expert produces.
Minimum Thickness of Wire - You can change this parameter by selecting from the list another minimum wire thickness that PI Expert uses during transformer construction.
Maximum Terminations per Pin (for thin wires) and Maximum Terminations per Pin (for thick wires) - You can change the maximum number of terminations (separately for thin and thick wires) that PI Expert makes on each pin of the transformer by default. This can be important if very large wire sizes are used as it may become difficult to terminate many thick wires on a single transformer pin.
