Delete a curtain grid

To delete a curtain grid, all one has to do is to select the grid line (by TABbing) and then press delete.

If the grid line is pinned, you have to unpin before deleting.

If the grid is part of the “type driven curtain wall”, Revit does not allow you to delete the grid line and does not give any warnings nor indication. (However, if you select the gridline and the mullions along the gridline of the “type driven curtain wall” and try to delete them, Revit gives this warning. )

You can use the ‘Add or remove segments’ in the option bar, after selecting the grid line, to remove segments of the grid line.

If you try to delete all the segments, using this command, Revit gives a warning:

 

The resultant curtain wall has split mullions because of the existence of the ghost grid line like:

Sometimes this split mullions can create cleanup issues in the elevation. This can be solved only by deleting the grid line. To do this, select the CW and change its type to “Curtain Wall: Curtain Wall 1”

 

This is a default CW type that is fully customizable and does not have many ‘type driven values”. After you change the type, Revit gives this warning:

Press OK. (If you select “Delete Gridline” Revit will remove your existing grid lines and mullions!) You should not see much changes in your CW. Now the CW is not a type driven element and so, Revit will allow you to delete the ghost grid line.
