Modify concrete column alignment or specify offsets
Once you have created columns, you can adjust their alignments and specify their offsets, if necessary. You can adjust the alignment of a single column in the Properties window or the Properties dialog box, whereas multiple columns can only be realigned in the Properties window.
Note:
Unlike columns made of other materials, the snap points and offsets of concrete columns directly affect the solver model. Concrete column solver elements are always located at the centroid of each stack. For further details, see: Rigid offsets example 1 - concrete column
