Locking Columns to a Grid

You can constrain the current position of vertical columns or the tops and bases of slanted columns to a grid. This state allows you to move the grid and keep columns or ends in their respective orientation to their grid placement.

To lock vertical columns to a grid

Valid columns must be within a grid and have a valid column location mark.

Select the vertical columns to lock to the grid.
On the Properties palette, under the Constraints section, select Moves with Grids.
Click Apply.
The modified columns may still be moved and modified but they will proportionately move with the grid if it is repositioned.

To lock slanted columns to a grid

Because the ends of a slanted column move independently from one another, it is possible to lock the column tops, bases, or both to the project grid.

Select the slanted columns to be locked.
On the Properties palette, under the Constraints section, select Move Top With grids, Move Base With Grids, or both parameters.

Because of the unique orientation properties of slanted column ends, locking to grids requires situational guidelines.

If both ends are locked to a grid and the grids at each end are not a subset of each other, the Column Style parameter (see Structural Column Instance Properties) of the columns will be changed to Slanted - End Point Driven.
Movement of a grid to which an angle-driven column is locked will move the entire column.
Movement of a grid to which an endpoint-driven column is locked will move only that end of the column. The column will lengthen or shorten to meet the new location of the grid.
