4.Edit the dimension in the dialog-box  

Negative Dimensions? Do not delete the Negative sign from a negative dimension.

See: Why a dimension is negative.

5.Click OK-tiny-13-17 to close the Dimension dialog-box

The Dimension is now in the graphic-area.

Notes:

When sketch-elements are fully defined, you cannot add any more dimensions or constraints.

You cannot add a driven-dimension in the Part-Editor. Alternatively, use add Measurement FB in the Mechanism-Editor as a driven-dimension.

Generally, do not make a dimension zero. It is better to add a constraint to move Lines or Points together. See Sketch-Constraints

To edit a Dimension:

1.De-select all other commands

2.Double-click the arrowhead of a dimension element


Why the arrowhead?

MechDesigner does NOT respond if you click the Dimension Number

It is easier to click the arrowhead than to click the dimension-lines or extension-lines.
