Inventor – Constraint Options
The Constraint Options dialog provides the user a way to select what inferred constraints they wish to reference in the 2D sketch environment. Along with the Inferred Constraints toggle, this allows for additional customization and flexibility.
I have noticed a few discussions resulting in the “Missing Green Dot” issue, and read a good amount of troubleshooting before (if ever) someone mentioned the Constraint Options. Sometimes it is just that simple.
The Constraint Options can be accessed through the Right Click Context menu. The selected options will infer constraints in the 2D environment. Everything else will be ignored. Note that in the above example, intersection constraints will not be inferred.
Should you notice your co-worker face down on the keyboard murmuring something about the Missing “Green Dot”, be a kind soul and fix their Constraint Options.

so im a student and im working on Autodesk Inventor 2009. its quite confusing and i have a test about inventor. The constraints and everything confuse me even though there are pictures to show us what kind of constraints you can make. its just so confusing.
Constraints are simply intelligent glue that follow instructions. A rectangle typically has a 1 Horizontal, 2 parallel, and 1 Perpendicular constraint that keeps the rectangle orthogonal and parallel. Remove the perpendicular constraint, and you get a parallelogram when modifying the sketch.
