I believe that it is impossible to influence the range of dimension ticks or arrows that are included with the OTB Revit, Arch, Str, MEP etc, but does anyone know if it is possible using the Revit Software Development Kit? I wish to know because I would like to have a dimension 'tick' that shows as 'X' not the usual '/' and do not want to launch into learning how to use the SDK if it is not able to help.
I would recommend you contacting our ADN development team directly:
Hope that helps!
