Detail sheets look nicer with a grid. The grid also encourages us to think about how details align, and forces us to be economical with the space we have for annotaions. Also it's standard practice.
The grid deployment has two parts: The grid module object, and the Detail Sheet master layout in PM.
All details should be developed with the detail module object. Place it before doing any annotations, so you can use it to align the notes. Most details should need only one grid cell. For larger details, stretch the object to an adequate extent.
The grid is designed to fill the standard title block. The grid itself must be drawn in PM. To make this easier, detail sheets have a special master layout with a drawing showing guidelines for the grid. The drawing also has hotspots at the cell corners for snapping the details into place. The lines must be drawn in PM in order to accommodate details of more than one cell. The lines should be drawn with a '3' weight pen.
The grid drawing exists in the project templates in three detail windows, one for each sheet size. Like with the title block details, the unneeded ones can be deleted.
Wall sections need not be placed on a detail grid, although you can place a wall section on a detail sheet if you have space. Better than making a new sheet for just one section.
Details' drawing titles should use the 'Medium' text size setting.
