Build snap fit feature starting from 3D point

Build a snap fit feature on a part starting from a 3D point.

  1. Create or import a thin walled part. The goal is to place a Snap fit feature on the circular edge at a position that is not convenient for the “on sketch” positioning style. For example, use a point on the edge where the hook direction is unlikely to be aligned with a sketch X or Y axis.
  2. Build the construction elements and a 3D work point on the internal wall edge at the position where the Snap fit is desired. For example, the 3D work point can be the end of a line that is tangent to the internal edge. The hook direction can be a work axis defined by the 3D work point and the center of the circular edge.
  3. Click 3D Model tab Plastic Part panel Snap Fit and make sure that the Placement method is On Point.
  4. Select the work point defined in step 2 as the Center. Select the blue face in the image as the Direction and the work axis defined in step 2 as the hook direction.
  5. Adjust the shape parameters as desired and click OK.
