CHAPTER 14. SPECIFYING THE PROBLEM GEOMETRY

a) The first vertex is selected. It is then clicked and the left mouse button held down.
bi ) The selected vertex is dragged over the target vertex (a red rectangle signifies that the
two will be merged upon release the left mouse button). The left mouse button is then
released.
bii and c) The above steps are repeated for the second vertex.

Overlapping Geometry Objects
To overlap one Solid object with another, drag the former over the latter. This process will then
split the original two Solid objects into three new Solid objects. If a Solid object is dragged
over more than one other Solid object then a multiple split will be carried out.
For the example in Figure 14.10, two initially unconnected square solid zones are to be modified
so that, after the process is completed, they overlap one another:
1. The first solid is selected. It is then clicked and the left mouse button held down.
2. The selected solid is dragged over the target solid and the left mouse button is then
released.
3. A new zone is created by the overlapping areas of the two solids. Should the two original
solids have different associated Slab Definitions and properties (as in this case), the new
zone will contain the properties and structural objects of one of the original solids. It is
undefined as to which solid the properties will be duplicated from.

dragging the solid and c) dropping the solid and creation of a new zone.
