Once installed, the "Sketch Checker" add-in will create a new button in the menu of the "Model" workspace's "Inspect" panel.

Though unlike Inventor, Fusion does not require the sketch curves to connect to each other through a sketch point in order to use the enclosed area as a profile for solid creation, it could be considered a good practice and can make the sketch look cleaner.

Unfortunately if you do not follow that practice, the add-in will highlight false issues as well along the real ones.

However, most of the time you should still be able to visually distinguish false results from good ones, since the real issues are where the curves "seem to be" connected, but they are not.

Once the points have been highlighted the command finishes, so pressing Escape key won't remove the highlight from the sketch points. In order to remove the highlight from the points just click anywhere in an empty space inside the sketch.
