Build boss feature using On Point for placement

Build a boss feature (Thread component) on a part using On Point placement.

1. Create or import a thin-walled part. Place a Boss feature on the circular edge at a position that is not convenient for the “on sketch” positioning style. For example, choose a point on the edge where the hook direction is not likely to be aligned with a sketch X or Y axis.
   
2. Build the construction elements. Create one sketch point and one 3D work feature where the bosses are needed.
   
3. On the ribbon, click 3D Model tab Plastic Part panel Boss .
4. Verify that the Boss type is Thread and that Placement method is On Point.
5. Select the points defined in step 2 as the Centers. Select a vertical edge like the one in the image as the Direction.
   
6. When the direction is defined (it is the same for all the bosses in the same feature), the preview displays.
   
7. Verify that the bosses can extend to the target body, for example, their projection is completely within the part body boundary.
   
8. Adjust the dimensions as necessary, and assign a fillet for the intersection boss-part body.
   
9. Stiffening ribs are not necessary here. Click OK to complete the Boss.
