To modify column eccentricities

Note: The changes only affect the default values that appear in the dialog boxes. Making changes to the defaults will not change the settings of members placed prior to the change.

Select either:

Layout > Columns > Assign Eccentricity

or
the Eccentricity tool from the Layout Column dynamic toolbar

The Assign Column Eccentricity dialog opens.

For the Strong Axis Eccentricity, select the method by which eccentricity is specified:

To calculate eccentricity as…	Do this…
1/2 the column dimension plus a specified distance	select the Distance + 1/2 Column Dimension option
an absolute distance from the column centerline	select the Absolute Distance from Center Line option

Type a Distance as it applies to the option selected in step 2.
Repeat steps 2 and 3 for the Weak Axis Eccentricity.
Select a Single column or Fence a group of columns to apply the eccentricties.
