Step 3.7: Trouble-shoot Geometry

Trouble-shooting Geometry.
You will frequently need to correct a sketch [trouble-shoot] with the Part-Editor.
Below, we list the most frequent problems and the procedures to follow to resolve them.
Where is my Sketch?

If your sketch 'disappears':

Example problems:

Why is my sketch BLACK when it should be BLUE?
Sketch-elements become BLACK when you believe they should be BLUE. To correct this problem, do one of these actions:
If the sketch-elements remain BLACK, then
-or-
* You cannot see constraints in the graphic-area. To delete a constraint you must 'find the constraint':
- or -
You may need to delete more than one constraint. When sketch-elements becomes BLUE, add a different constraint or the sketch-element again. |
Why is my sketch Blue, and I cannot add another constraint to make it Black?
Sometimes, a sketch-element is BLUE and you cannot add more constraints. You might be able to drag a sketch-element that is BLUE, but when you come to add a new constraint, MechDesigner does not accept it. In this case, a new constraint may need to remove two degrees-of-freedom, but the sketch has only one degree-of-freedom. Example: Coincident-Constraint If: the end-Point of a Line has a Coincident Constraint with a different Line Then: it is not possible to also add a Coincident-Constraint with the same Point and a Point along the Line. To delete the constraint:
