Freecad Constraint Coincident - Point Line Circle - Freecad Pad Wire is not Closed

The Coincident Constraint (shortcut: C) is the "glue" of the Sketcher workbench. Its primary job is to make two things occupy the same space. How it Works: The different Modes In FreeCAD 1.0, the coincident tool is more "intelligent" and often acts as a unified tool for several tasks: 1. Point-to-Point: Locks two vertices (endpoints, centers of circles, or the origin) together so they move as one. 2. Point-to-Object: Locks a point onto a line, circle, or arc. The point can slide along the object but cannot leave it. 3. Concentric (Circles/Arcs): If you select two circles or arcs, it automatically aligns their center points. 4. Point to Coordinate Axis In FreeCAD 1.0, the X and Y axes in your sketch are treated as infinite lines. The Action: Select a point (like the center of a circle) and then select the horizontal or vertical axis line. The Result: The point becomes locked to that axis. It’s effectively a "Point-on-Object" constraint, but specifically for the sketch's coordinate system. 5. Segment to Segment (Collinear-ish) If you select two line segments (not the endpoints, but the lines themselves) and apply a coincident constraint: The Result: FreeCAD will often interpret this as a request to make the lines Collinear. They will now lie on the same infinite line, even if they don't touch. Note: In newer versions, FreeCAD might prompt you or automatically switch to the "Collinear" constraint icon, but the logic is triggered by the same "make these things occupy the same space" intent.
