Building the Hook and Slider

The last steps in building the geometry of the latch model are:

•	Creating the Hook and the Slider

•	Connecting the Parts Using Revolute Joints

•	Simulating Your Model

•	Saving Your Database

Creating the Hook and the Slider

You now create the hook using the Extrusion tool. An extrusion is a three-dimensional object defined by its profile and depth. To create an extrusion, you draw a polyline that defines the extrusion’s profile. By default, Adams/View extrudes the profile along a line perpendicular to the working grid.

To create the hook:

1.	Select the Extrusion tool .

2.	Be sure that Create profile by: is set to Points and Closed is selected.

3.	Select Path: to About Center.

4.	In the Length text box, enter 1, and then press Enter.

5.	Click the locations listed in Table 2.

6.	To close the extrusion, right-click.

Small boxes, called hot points, appear at the vertices of the extrusion.

Note:

Sometimes Adams/View snaps to the nearest object instead of snapping to a coordinate value. To override this, hold down the Ctrl key and move the cursor until you select the desired coordinate.

Table 2 Extrusion Coordinate Values

X location:	Y location:	Z location:
5	3	0
3	5	0
-6	6	0
-14	6	0
-15	5	0
-15	3	0
-14	1	0
-12	1	0
-12	3	0
-5	3	0
4	2	0

Note:

If you make a mistake while creating the extrusion, continue creating the extrusion, and then, at the end, use the extrusion hot points to place the points in the correct locations. You can also use the Undo tool to cancel any of the changes you made. You can undo up to 10 actions.

7.	Right-click to stop selecting locations and create the geometry.

8.	Rename the extrusion part to hook.

To create the slider:

1.	Create two more design points, POINT_8 and POINT_9, at the locations shown in Table 3.

Table 3 Points Coordinate Locations

	X location:	Y location:	Z location:
POINT_8	-1	10	0
POINT_9	-6	5	0

2.	Create a link connecting these two new design points. Again, before you click, make sure the point labels are visible.

3.	Rename the link part to slider.

Connecting the Parts Using Revolute Joints

You now create three more revolute joints.

•	Place revolute joints at the following locations using the construction method 2 Bod - 1 Loc, and Normal To Grid:

•	Between the handle and the slider at POINT_8.

•	Between the slider and the hook at POINT_9.

•	Between the hook and the pivot at POINT_2.

Tip:	You can see the names of objects that are in the same location by right-clicking on the objects. A shortcut menu appears with the names of all the objects at that location. This is also helpful if you have forgotten the names of objects.

Simulating Your Model

In this section you simulate again to see if you’ve assembled the parts and joints properly. During this simulation, the handle, the hook, and the slider move in a circular motion with respect to the pivot, as the pivot moves in a circular motion with respect to ground. The only force acting on this model is gravity, since you have not assigned any forces to it.

To simulate the motion of your model:

1.	Select the Simulation tool.

2.	Run a .2 second, 200-step simulation.

3.	Select the Reset tool to return to the initial model configuration.

Saving Your Database

Use the Save Database As command to save the current modeling database as an Adams/View binary file. Saving your modeling database as a binary file saves all modeling information.

To save your database:

•	From the File menu, select Save Database As, and then save the file as build.
