3D Gridlines

3D Gridlines

Win64, English

On Target BIM
Inserts 2D/3D gridline family at chosen levels with user defined offset. Export gridlines in NWC to help your coordination team.

General Usage Instructions

Simply click on the 3D Gridlines ribbon button in the OTBIM tab, and you will be asked for the following selections:

  • Choose to use the included family or one of your own. (Generic model - line based family with a text parameter to accept the grid name)
  • Select one or more levels using standard Windows Ctrl & Shift selection.
  • If you want your 3D grids to be above or below each of the selected levels, enter an offset value. Offset values can accept standard Autodesk® Revit® units measurements.
  • If you choose to use your own custom family, select which parameter should be mapped to the grid name parameter.


There are 2 included types in the standard OTB family:

  • 2D & 3D Grids - In addition to the 3D grids for model coordination, this type also has annotations at selected intervals along the gridlines for easy reference in plan views.
  • 3D Only - Hides the annotation markers in plan views. 3D grids are visible in fine detail views, and export to NWC for coordination.


The included family has the following user parameters to customize:

  • 3D Grid Height - Default 4" - Controls the height of the 3D letters in your model.
  • 3D Grid Spacing - Default 10' - Controls the approximate spacing for the 3D (and 2D) grid markers.
  • Line Size - Default 1/8" - Controls the size of the "line" extrusion in the model.
