In the new drawing open the AutoCAD Dimension Style Manager, and then go to “Modify”.With the “problem” drawing open, start a new drawing file.There are suggestions to change the dimstyle so that it isn’t using the tick mark, then purge the tick mark block, _ArchTick, out of the drawing, and then reset the dimstyle back to having a tick mark. Instead of trying to do that, what you can do is redefine the block, _ArchTick, using the AutoCAD DesignCenter. The issue was within a particular AutoCAD drawing where a dimension style that contained architectural tick marks was being used, but the tick marks weren’t showing up in the drawing. I recently came across an interesting problem within AutoCAD.
