How can alternate solutions for a linear dimension be displayed?

Displaying alternate solutions for a linear dimension can specifically be achieved through the use of a designated command designed for this purpose. The Alternate Solution command is tailored to handle situations where a design can accommodate multiple valid dimension configurations. By accessing this command, users can easily visualize and compare different dimensional values that could fulfill the design requirements, thus facilitating decision-making in the design process.

The other options do not present mechanisms for displaying alternate dimensions. Designing features, such as using the Trim command, focuses on modifying geometric entities rather than managing dimensional variations. Simply entering a positive value for the dimension type would not inherently provide an alternate solution but rather just set the dimension to a specified value. Adjusting the length of the dimension line influences the appearance of the dimension but does not introduce or display alternative dimensional values. Each of these choices serves a different purpose in the modeling process and does not align with the functionality that the Alternate Solution command offers.
