From the Autodesk App Store:
The “Auto Dimension Column and grid Tool” is an Autodesk® Revit® Add-On that aims to the automatic dimension between grid and column with offsets from column and dimension type which the user can specify.
Instead of wasting time in dimensioning each face of the column with the nearest grid or axis you can easily select all columns and grids needed. With only one click all dimensions from the face of each column to the nearest grid are placed.
