The length of a structural member is its logical length—the length between its grip points—rather than the actual length, which can be difficult to compute. To get the actual length, you can add the Length along Baseline property, which projects all parts of the member to its baseline for measurement. This property will give the actual length for members to which trim planes or offsets are applied or when interference conditions or body modifiers affect the overall length. Such members give a visible length that is different from the logical length.
The location properties of a structural member (X, Y, Z) give information about the coordinates on which a structural member has been inserted. This is important for downstream applications in the structural engineering field.
