This information was previously posted as part of another article, to which Vajrang Parvate (SolidWorks Corp Sr. Manager, Drawings Development) replied with an additional helpful hint. I’m reposting as a separate article to highlight the information.
Deleting Dimensions behavior
SolidWorks has a new user-selectable behavior when a dimension is deleted. If the user deletes a dimension or even just removes text from a dimension, SolidWorks has the ability to automatically realign the spacing of the neighboring dimensions to get rid of gaps caused by that deletion. The user has the option to turn this ability on by going to Tools>Options…>Document Properties>Dimensions to select the Adjust spacing when dimensions are deleted or text is removed checkbox.
Undoing the deletion
From Parvate:
…When the “Adjust spacing when dimensions” checkbox is checked and SolidWorks moves in dimensions after one is deleted, two commands are added to the undo stack : one for the deletion of the dimension and another for the movement of the rest of the dimensions. So hitting Ctrl-Z will undo the deletion in two steps.
