Introduction to copying of entities

Copying of members is an easy way to create models of complex structure. This is useful particularly if the geometry of the modelled structure shows at least a few signs of regularity.

Members may be copied one by one or en bloc. It is possible to create only one or more copies at a time. If required, additional members may interconnect the individual copies with the original and with each other in specified point.

In general, the user may choose from the following approaches:

• making a single copy of the original using menu function,

• making a single copy of the original using the pop-up menu of the graphical window,

• making multiple copies at a time with an advanced definition of copy parameters (e.g. the copied members may rotate simultaneously with being shifted)
