Point Symbols

 '+' : centre-Point - at the centre of Arcs and Circles [Also, 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]. '○' : start-Point or end-Point - at the ends of Lines and Arcs : centre-Point that is also coincident with a start-Point [or end-Point]. You may need to select the '+' or the '○' to do a command, and it is important to know the difference between the two Points, and to be able to select one Point or the other Point. ' : Locked-Points - as defined by the 'Position and Vectors dialog-box' ○   : Free-Points are Blue : Motion-Point - added to a sketch-element with Add Motion-Path FB. : Motion-Point coincident with a start-Point or end-Point.

Point:  Trace-Point

You can drag a Point in the Mechanism-Editor, if you:

 1 Add a Point in the Part-Editor

AND ...

 2 Do not add a dimension or constraint to the Point

AND ...

 4 Add a Trace-Point to the Point in the Mechanism-Editor

Point: Locate the Point in one of two ways

 • Use dimensions and constraints in the Part-Editor

OR

 • in the Mechanism-Editor

NOT BOTH
