# Blocks
The block wizard can be activated from the Block table view using the wizard button. Blocks allow for rapid creation of models by allow replicas of groups of members to be defined.
# Definition
Name
An optional identifier for the block.
Members
The members to be assigned to this block. These can be either 1D or 2D members.
Replicate
The replicate feature allows multiple copies of a member to exist in the model. The copies (replicas) remain linked to the geometry of the original member.
Offset spacings can be defined in the global x, y and z directions. This can be in the format "4 4 4" to define three replicas at 4m spacing or using the shorthand "3@4" to create the same result. The syntax types can be mixed e.g. "6 3@4 8" to expand to five replicas with spacings of "6 4 4 4 8".
