The Re-Extrude command is used to re-extrude previously extruded domains
The Re-Extrude Filter panel shows a list of extrusion groups available for re-extrusion.
A single selection or homogeneous selection of multiple extruded structured
domains, structured blocks or prism blocks with the same extrusion method
and number of steps is required for you to enter directly into the Extrude
panel after clicking on Grid, Re-Extrude. Note that path extrusions created
along different connector paths are considered separate extrusions. Any
domains or blocks not created by extrusion, extruded domains or blocks
which were previously split, connectors and/or database entities also selected
will be ignored. A heterogeneous selection of domains and blocks, different
extrusion types and different numbers of steps will place you into the Re-
Extrude Filter panel shown above when Re-Extrude is selected from the Grid
menu. Simply select the extrusion group you wish to re-extrude at this time
and click on Re-Extrude.
Once you have selected an extrusion group to re-extrude, the remainder of
the task is identical to the Extrude command. For example, if
the mode of the group selected for re-extrusion is Normal, you will be placed
in the Normal, Run tab as if you were doing a Normal extrusion for the first time. To re-extrude
and be able to modify the Initial Δs (initial step size) and Orientation
in the Attributes tab, you must first use the Restart command. Or you can
modify the existing extrusion by using Run 1, which will run a single step
forward, and Back 1, which will back up your extrusion one step.
When changes are made to the extrusion attributes for a domain or block,
linkages with adjacent domains or blocks will automatically be maintained. If
you do not wish to keep these linkages, then you must first cut and paste the
extruded domain or block using the Edit, Cut and
commands, respectively. Once you are in the Paste panel,
select Re-Extrude to re-extrude the domain or block without
Note that if a domain belongs to a block and is selected for re-extrusion, the
re-extruded domain should contain the same number of extrusion steps as the
original domain. If the number of steps differs from the original extruded
domain, the resulting block will be unbalanced even though the reextruded
domain is saved.
