Edit a Dimension

To edit a dimension:

1.If necessary, de-select 'Add Dimension' [OR: to add a dimension, Add Dimension cannot be active].


2.Double-click the arrowhead of the dimension or dimension or extension lines [ OR: do not double-click the dimension number].

Color of Sketch-Elements


Blue: sketch-elements are not fully-defined.
Cyan: sketch-elements are fully-defined [default colour]


Sketch-elements are the same color as the Part-Outline:

Green: sketch-elements are Green if the Part-Outline is Green.

Blue: sketch-elements are Blue if the Part-Outline is Blue.

Trouble-shoot Geometry

Use CTRL+Z (Undo) or the Delete button:

If one or more sketch-elements 'disappear', then CTRL+Z , possibly again and again.
If a sketch-element is black, and it should be blue, delete the sketch-element, and add it again.
If an angle dimension will not increase to be greater than 180º, then delete the dimension, move the sketch-element, add the dimension again.
If a dimension gets 'stuck' at 0, (angular or linear dimension) delete the dimension, and add the dimension again.

'Fix' Constraint

To Fix a Point: use the Lock & Specify check box in the Point Vectors and Position dialog-box.

It is not possible to use the Lock and Specify check box if the point has any another constraint.
