Adding a New Mass Element to a Mass Group
Use this procedure to add a new mass element to a mass group after you have
placed a mass group in the drawing.
1 Select an existing mass group or mass group marker.
2 Click Mass Group tab ➤ Modify panel ➤ Add New Element.
3 On the Properties palette, select a shape for the mass element.
4 Select Add, Subtract, or Intersect for Operation.
5 Specify an insertion point in the drawing.
6 Specify additional parameters for the mass element.
Depending on the shape of the mass element, you need to specify
a second corner, the radius, or the height.
7 Specify a rotation angle, and press ENTER.
The newly created mass element is now part of the selected mass group.
Attaching an Existing Mass Element to a Group
Use this procedure to add existing mass elements to a mass group. When an
element is attached to a mass group, the element display is turned off and the
group display is turned on.
While it is possible to attach any number of objects to a single mass group,
performance improves if this group is subdivided into a series of nested groups.
Your design is also more manageable if a group is broken into logical divisions.
In addition, if one of the subgroups fails to display as expected, it is easier to
track down the problem. In most cases, you can adjust the order of the objects
in the group to get the correct appearance.
1 Select the mass group.
2 Select the Attach Elements grip.
Alternatively, you can click Mass Group tab ➤ Modify
panel ➤ Attach Elements .
