  • I think you're using the command correctly. "dbGet head.layers.spacingTables" shouldn't return 0x0.

    I just tried using 9.1.USR1 and 8.1.USR3 and it working as desired.  What version are you using?  If you're using 8.1.USR3 or newer perhaps you could file a service request or provide more information.

    Thanks,
    Bob

       SPACINGTABLE
      PARALLELRUNLENGTH     0.00    1.00    1.50    4.50
      WIDTH    0.00         0.20    0.20    0.20    0.20
      WIDTH    0.39         0.20    0.24    0.24    0.24
      WIDTH    1.50         0.20    0.24    0.50    0.50
      WIDTH    4.50         0.20    0.24    0.50    1.50 ;

    But  ,  I  have  only  this  lef  file  ,  how  to  do ?
