How to define fitting dimensions

Example 1

can somebody check these for me? Esp. the second one ***

In the example below, the fitting item is a 20mm thick plate. As this is a non-linear section (and the Size: Dimensional check box is not selected), dimensions are needed for the width and length of the fitting.

The width of the fitting is based on the width of the member. It is 100% of the member's width plus an additional 20mm.

The length of the fitting is based on the depth of the member. It is 205% of the member's length.

If this fitting was applied to a 254X146X31UB, its dimensions would be 520.7X166mm.

Example 2

In the example below, the fitting item is a 25X25X5 equal angle. As this is a linear section, only the length of the fitting needs to be specified.

The length of the fitting is a fixed dimension of 120mm. It is entered into the Fixed Size field.
