Point Tool

Ribbon menu Bodies tab Construction container Point Tool
or
(Classic) Build Bodies/Geometry Point Tool
Defines locations in three-dimensional space upon which you can build your model. Points allow you to build parameterization between objects, as well as position objects. For example, you can attach a link to points so that each time you move the points, the link’s geometry changes accordingly.
You can also use points to define the location where modeling objects connect, such as the point where a joint connects two parts. Points do not define an orientation, only a location.
As you create a point, you define whether Adams View should add it to ground or to another part. In addition, you specify whether other parts near the same location should be attached (parameterized) to the point. If you attach other bodies to the point, then the location of those bodies is tied to the location of that point. As you change the location of the point, the location of all attached bodies change accordingly.
 
Note:  
You should not attach a part’s center of mass marker to a point, however. If you attach a center of mass marker, Adams View removes the parameterization whenever it recomputes the center of a part, unless you defined mass properties for the part.

For the option:
Do the following:
New Part/Add to Part/On Ground
Select either:
New Part - Creates a new part.
Add to Part - Adds point to another part in your model.
On Ground - Adds the point to ground.
Note: Add geometry to ground if the geometry does not move or influence the simulation of your model. For example, if you are simulating a car driving around a race track, the geometry that defines the race track can be added to ground.
Don't Attach/Attach Near
Don't Attach - Keep other objects surrounding the point unattached to the point. There will be no parameterization relationship set up.
Attach Near - Attach other nearby objects to the point. When you change the location of the points, the other objects locations and orientations update accordingly.
 
Note:  
After creating the point, you can modify its name and set its location using the Table Editor. Learn about Editing Objects Using the Table Editor.
