Creating Feature Points

Make sure DVTI_dcsShowPoint Show Points is on so that the points will be shown in the Graphics Window as they are created.

Fast Point Creation allows the user to create Feature Points, Coordinate Points or Circle Center Points. While the Fast Point Creation dialog is open, a point will be created on any surface, hole, or pin that is clicked. Multiple points can be created in a row. If you make a mistake when creating Fast Points, click [Undo] to remove the last point.

 

With the Fast Point Creation dialog open, click each of the three surfaces highlighted in the Turnlamp in the figure below to create a point on each surface. Select the flat surface on each leg. It is best to spread the points as far as possible from one another to most accurately represent the interaction of the parts during the moves that will be created later.

Click [Close] in the Fast Point Creation dialog.

 

We would also like to create points at the center of the pins that will be used to move the Turnlamp and Headlamp to the Bracket.

 

In the Feature Points dialog, select Center in the Feature Point Parameters  Point Method section of the dialog to begin creating a point at the center of the feature.

Select [Feature] in the Feature Points dialog to enter the Pick Feat dialog.

Select either half (if the pin is not viewed as one continuous cylindrical feature from the CAD geometry) of the pin shown in the image below.

Set the V value in the Feature Points dialog to "0.5" to put the point at the midpoint along the axis of the pin.
