In the Part-Editor, use the Geometry menu and toolbar to add sketch-elements, dimensions, and to use the Merge-Points tool.
See also: Constraints menu and toolbar to add constraints to and between sketch-elements.
In the Part-Editor, the Geometry toolbar is to the left of the graphic-area.
Edit a Dimension
To edit a dimension:
1.If necessary, de-select Add Dimension and all commands.
2.Double-click the arrowhead of a dimension or extension line ( do not double-click the dimension number).
Color of Sketch-Elements in the Part-Editor (see also Application-Settings > Graphics > Display colors ) (assuming colors for these geometry states are set to Blue, Black and Green)
•Blue: sketch-elements are not fully-defined.
•Black: sketch-elements are fully-defined (default color)
Color of Sketch-Elements in the Mechanism-Editor (see also Application-Settings > Graphics > Display colors ) (assuming colors for these geometry states are set to Blue, Black and Green)
•Green: sketch-elements are Green if the Part-Outline is Green.
•Blue: sketch-elements are Blue if the Part-Outline is Blue.
Use CTRL+Z (Undo) or the Delete button:
•If one or more sketch-elements disappear, then CTRL+Z, and possibly again and again.
•If a sketch-element is Black, and it should be Blue, delete the sketch-element, and add it again.
OR, SHIFT+CLICK a sketch-element, start-Point, end-Point, or center-Point to show its constraints in the Selection-Window, and delete as required.
•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.
To FIX a Point, start-Point, end-Point, or center-Point, or a Point: use the Lock & Specify check-box in the Point Vectors and Position dialog-box.
It is not possible to FIX a Point with the Lock and Specify check-box if the Point has any another constraint.
