Result : |
If the two sketch-elements have a total of more than two degrees-of-freedom:
- or -
- or -
Note: If the two sketch-elements have a total of 1 degree-of-freedom, then the two sketch-elements cannot become 'coincident'. |

To Delete : |
The sketch-element and Coincident Constraint show in the Selection-Window.

In MechDesigner, you cannot remove more than two degrees-of-freedom from a Point. For example, you cannot do these two steps:
Why:
Thus, delete the constraint between the Point and the Line (STEP 1), before you add the constraint between the two Points (STEP 2). About Point Symbols
You may need to select the '+' or the 'O' with a command, and it is important to see the difference between the two Points and be able to select one Point or the other Point. When a centre-Point is Merged with a start-Point or end-Point of a Line or Arc, the symbol is a '+'. You cannot select one or the other, because there is only one Point.

Notes : |
Use Add Coincident between two Points for construction geometry. Use Merge-Points for sketch-loops and sketch-paths. Points that are 'coincident' give you the option to delete the Coincident Constraint later. |
