9.1.1. Selecting Entities Using Commands
Table 9.2: Select Commands (p. 211) shows a summary of commands available to select subsets of entities.
Notice the "crossover" commands: commands that allow you to select one entity based on another entity.
For example, you can select all keypoints attached to the current subset of lines. Here is a typical sequence
of select commands:
LSEL,S,LOC,Y,2,6 ! Select lines that have center locations between Y=2 and Y=6
LSEL,A,LOC,Y,9,10 ! Add lines with center locations between Y=9 and Y=10
NSLL,S,1 ! Select all nodes on the selected lines
ESLN ! Select all elements attached to selected nodes
See the LSEL, NSLL, and ESLN command descriptions in the Command Reference for further information.
