Joining Bodies

You can use the Join command to create join features on the associated bodies.

1. Click Join .

   The Join dialog box appears.

   
   
   

   Important: By default during the creation of the Join, the Head and Thread buttons are selected. If the active body (in this case, Divide Body.3) is the result of a divide and its associated non-active body (Divide Body.4) is present, the associated body is automatically selected as the entry in the Body to join box. Otherwise this box is blank. During the join creation, this box can be cleared by clicking Head or Thread to deselect them. In this case, the join feature will be a head or thread depending on which button is set; the associated join feature cannot be created afterwards. By selecting both head and thread options, the Body to join box is re-activated. And you may need to select a body in the Body to join box. Once you click OK, neither the Body to join box nor the Head and Thread options can be changed when editing them. When the Join is edited, the Body to join box will display the name of the associated body in gray color.

2. Select the point in the center of the plane (Sketch.2) as the Sketch for the Screw Positions.

   
   
   

   At each non-construction point defined in the sketch, a screw will be positioned. The tip of the arrow points to the body that will be the thread.

   
   
   
   
   

   In this case, the lower body will have the head geometry constructed within it. While the upper body will have the thread geometry. By either clicking on the arrow or clicking on the Reverse Direction button, the tip of the arrow will be reversed, and therefore the geometries will be the opposite from what was described (i.e. the lower body contains the thread geometry while the upper body contains the head geometry).

3. Define the parameters in the Screw, Head, Shank, Clamp and Thread tabs.

   
   
   
   
   
   
   

4. Now that the desired join feature has been defined, click OK to create the feature.

   
   
   

You can define gussets around the head and the thread of a join feature. A join feature often has stiffening gussets around the head, thread or both.

1. Click Join.1 under Divide Body.2 in the specification tree.

   
   
   

2. Select the Gusset tab.

3. Click Head in Gusset.

4. Uncheck Thread in Join Features.

5. Click OK.

   The geometry is produced for each of the points. Gussets are created only for the inside shapes. The geometry created for the outside point and outside portion of the boundary point do not have gussets.
