• S/E Status (Model/Drawing).
It is just really strongly recommended that all building elevations and sections be model views. Developing model sections is a little harder than elevations, but anyone can do it with practice.
I usually keep S/E's set to Auto-rebuild.
• S/E Element Placement. Marker ends should not extend too far beyond the building itself. Our section elements go on a non-printing layer, and we use a separate object to show the section locations in plan. This is because it is difficult to reconcile the extent of the cut with the desired graphic presentation of the markers. That is, To get the markers looking nice you need have them much more extensive than is required to create the view itself.
Cut sections using the section marker Plain Section JAM9. This simple marker just shows the ID and a flag to indicate direction.
Elevations should be as close to the building as possible; the marker should be stepped where necessary to achieve this. Watch out for eaves and gutters.
Sections often require a lot of tweaking to get them to cut through interesting/clear/consistent stuff on all stories. Watch for undesirable effects of stepping with respect to roofs. Where a section cut is perpendicular to a roof's slope, try to avoid stepping the section within that roof. If you can't avoid it, discontinuities in the roof can be patched, but the patch becomes a maintenance issue if you edit the S/E element again.
Section depth should be minimized in order to improve performance. The depth should reach only the most distant element you want to see; usually it's a ridge or a chimney. Infinite depth sections should never be used. Zero-depth sections come in handy sometimes for generating details, but building and wall sections should always have some depth. Section depths are typically off in display options; toggle them using Karl's marvelous add-on.
• Layers. All annotations go on the layer +A Arch Note Reg Scale. This includes text, arcs and splines used for leaders, and notation objects. All added 2D work should go on +A Misc Line, but this is not a critical issue. Since S/E windows usually only generate a single view, layer discipline is not as important as in the plan. You should, however, make consistent use of the Arch Note layer, to maintain the option of turning the notes off to display the S/E image by itself.
• Vectorial hatching.
Elevation (and 3D) hatching is generated by the 'Vectorial Hatching' setting of the material in Options -> Attribute Settings -> Materials. The pen of the hatching should typically be 150, which is light gray.
Display of the hatching is a setting in the model tab of the S/E element itself. Hatching slows down generation considerably; in typical use it should be off. Before publishing, turn the hatching on for all the markers by selecting all of them and checking the box in the info box. The hatching switch setting is not saved with views, which is too bad.
• Unwanted lines.
Ugly bits which are complex can be patched. To hide simple cases of a few unwanted lines, use a fill which matches the vectorial hatching of the elements involved (shingles, stone, etc.), and has an opaque background. For blank walls you can use a solid fill of a white-printing pen. I use 80, which is purple, so I can see the areas I've masked. Masking fills and patches should go on the layer +A Misc Line. The use of masking elements becomes a maintenance issue.
• Rendering of depth.
Foreground elements should be outlined with a heavy (5-weight) polyline. There is no reliable way to do this automatically, it's tedious. One tip: for symmetrical building parts, outline one half and then mirror. Another: Outlines can often be copied and pasted to the opposite-facing elevation and mirrored across the origin.
Use Marked Distant Area where appropriate. When using it, check 'Use One Pen' and use pen 30. Pen 30 is gray in AC and 1-weight black in PM. You need section depths on in display options to edit the MDA depth. Don't forget the shortcut.
When you combine outlining with MDA, you get three levels of rendering: Fills on and outlined, fills on with no outline, and fills off.
• Model pens. Except for walls and objects, elements are drawn in 3D with their floor plan pens. Walls have a dedicated 3D pen, which should be a 3-weight. (Typical walls are 13.) Objects can have a separate 3D pen, either as a parameter or hard-coded, this will vary. It is a long-standing wish that all elements have a separate 3D pen.
• The ground. The ground mesh section settings should be: Fill='Air Space'; Background pen=91; Cut pen=6-weight. (I like green land, so 36.) These settings give an invisible fill with a heavy ground line. The bottom and side lines of the mesh should be obscured by the object Grade Mask JAM8, which goes on the +A Misc Line layer.
Elevation notes. The main materials and building elements should be noted. This includes wall finishes, trim parts, decorative columns, panels, railings, chimneys, etc. To align the notes, use the object Note Column JAM9, in the drawing tools folder. Notes on the right side should be left-justified with the leaders starting at the first line. Notes on the left side should be right-justified with the leaders starting at the end of the last line.
It is permissible to fully annotate one elevation on each sheet, and then only point out unusual features on other drawings on the same sheet.
Levels. Use the object 'Elev Marker JAM8'. Elevation views should show the Z-height of each story. It is helpful to draw a dotted (not dashed) line through he elevation at each floor level. Dotted lines need to be heavy in order to be visible; use a 4- or 5-weight. In sections, levels should be should be shown for ceilings as well as floors, and for interior floor level changes (such as garage slabs). Level objects will auto-display their Y position, which is the height. They should be dimensioned to show the relationships among them.
Knee wall heights should be dimensioned in section.
In sections, unusual ceiling or floor conditions may be labeled with Slab Elev JM9. Examples: Lowered ceilings in small rooms, a stepped slab in a theater.
Roof pitches should be noted in section and elevation with the label Roof Slope JAM9.
Doors and windows should be labeled with Door-Window Label JAM9.
Structural members in section should be labeled with Description JAM9. Joists are shown 2D-only using 'Joists Sect 2D JAM9'. Our standards don't support modeling the joists.
