Edit/modify dimension of an entity

Hi.

How can I edit an entity (i.e. length) by changing its dimension value?

Normally in other drawing programs, we just edit the value then the shape will change directly after we ENTER the value to confirm.

Is it exist this method in DraftSight?

Or we only can edit the text of dimension without changing the shape directly unless we adjust the length manually and then dimension the size later until meet the needs?

Need reply to this matter ASAP.

Thank you.
