Executive summary: A new layer for elements in layouts and in the title block worksheets. There should be no elements on the Archicad layer.

• The title block object and other stuff in its detail/worksheet window
• Drawing elements on layouts starting in AC10
• Master layout drawings and annotation elements

And it's never given us any trouble, but.

The concrete reason to forswear use of the Archicad layer is that it interferes with Teamwork. The only way to have the Archicad layer in your workspace is to have 'exclusive access' to the project, which is inconvenient in a real shared workflow. It's true that we don't use Teamwork much, but you never know.

Rather than confront the question under deadline pressure some time in the future, I'm changing the standards and templates now to include a layer for 'Layout' elements. This layer, +Z Layout, holds any element placed directly on a layout, including drawing elements, texts, PDFs, etc. It is also the layer for the title block object and anything else within the title block worksheets. The layer is visible and unlocked in all layer combinations except 0 Working Model.

Once all that always-showing stuff is placed on a regular layer that could potentially be hidden, you might wonder how to make sure it always shows anyway. The layout environment actually has its own layer settings, which are maintained simultaneously with the model window layers. Changing the layer settings of one does not affect the other, thank goodness. The templates are set up with the +Z Layout visible in the layouts. As long as you leave it alone, it will always show. If you do hide it, probably by accident, and WOW you'll know right away when everything vanishes, turn it back on. Layout layers are unaffected by view changes. This should be a set-it-forget-it situation.

Some people use multiple layers to turn layout elements on and off, but I don't see the advantage of that for us at the moment. One concern would be that layout layers can't be saved, with views or otherwise, so the user must remember to manage the layers before publication. I would be inclined to handle such visibility control in the title block worksheets. Here is some AC-Talk discussion.

The other advantage of using this standard is that the Archicad layer rule is much simpler: Don't use it, full stop.

Template changes:
• New layer +Z Layout. Show in all combos except Working Model.
• All title block worksheet elements to the new layer. Use F&S for all elements on AC layer, then Edit Selection Set to change.
• Set layer environment layers to combo xxAll, which shows everything.
• All master layout elements to the new layer. On each master, use F&S and ESS as above.
• All drawing elements on regular layout to the new layer. In Drawing Manager, sort by Placed To, highlight all non-master drawings, change layer in settings.
• Change default layer of Drawing tool.
• Redefine Drawing tool favorites with the new layer.
• Save favorites.

A reference marker is a special object that can intelligently refer to viewpoints within the project or drawings placed on layouts. They also create viewpoints, which is a strange kind of double duty. Then you can also create viewpoints without markers... it's not intuitive overall. For most cases, you can think of a viewpoint as an application window. Sections, elevations, interior elevations, details, and worksheets are all viewpoints. So are schedules and even stories, but they are not related to the marker discussion in the same way. Everything in here applies equally to sections, elevations, and details.

A source marker creates a viewpoint. It is the viewpoint, in a manner of speaking. If you delete a source marker, you delete the viewpoint. If you copy a source marker, a new, additional viewpoint is created.

A linked marker is more like an object, though still a special one. When you place a linked marker, no viewpoint is created; the marker points to something. Any number of linked markers can point to a particular viewpoint or drawing. They are just pointers, and they can be created or destroyed without affecting anything else.

Both source and linked markers can refer to drawings.

You can have a viewpoint with no marker. Such a viewpoint is independent. You will very often have independent details. At this time all of our worksheets are independent. You can even have independent sections and elevations, but I don't see any advantage to these. Interior elevations can't be independent.

When you get ready to place a marker, whether to draw a new section or refer to an existing detail, you will see these choices in the info box:

When you select a marker, the options look like this:

You can turn a source marker into a linked marker and vice versa, but don't. It's complicated, potentially destructive, and I'm pretty sure it's silly. Treat your viewpoints as 'real' things, and use linked markers to point to drawings in any way you like.

In practice, a linked marker should always refer to a drawing. It makes for a smoother workflow if you place the drawing in the layout before placing linked markers.

When you choose to refer to the drawing rather than the viewpoint, you have three choices.

• The selected drawing lets you choose the drawing manually from the layout tree.

• The first placed drawing of the viewpoint means you don't have to choose the drawing. The marker will find the first drawing of that viewpoint in the set and refer to that. You can choose this option before the drawing is placed. If you go this route, make sure the first drawing is the only drawing, or you are sure the first one is the one you want. N.B.: In our layout tree, the schematics sub-book comes before the CDs, so this 'first' thing will always use a schematic elevation instead of the same elevation in the CDs.

• Similarly, the first drawing of the selected view lets you name a view in advance of placing any drawing. When the drawing is placed in due time, the marker will refer to it. This 'first' method is safer, because 'view' is more specific than 'viewpoint'. For example, the schematics and CDs use different views.

With a source marker, you can only choose a viewpoint, view, or drawing associated with the marker's viewpoint. A linked marker can point to anything.

When you have a source marker selected and you strike delete, you will get a warning to the effect that deleting a source marker will also delete that marker's viewpoint, unless you choose to keep it as independent. If you confirm that you want to delete the viewpoint along with the marker, you be warned again, to the effect that deleting sections (e.g.) is not undoable. This second warning is as old as the section tool itself, and you know what it means.

If you delete a viewpoint from the Project Map, you will only get the warning about undoability. When a viewpoint is deleted in this way, its source marker and any linked markers are automatically deleted.

When you delete a linked marker, you don't get a warning, because nothing important or non-undoable is happening.

Somewhere, a roof is unhappy. Most likely, the angles of nearby roof edges are causing the geometry to turn inside out. The report will say something like:

This is actually helpful! Use find and select to find a roof with that ID, and you can fix it. The trouble is that you probably have a lot of roofs with identical IDs, and you can't tell which of the n roofs is the problem.

If the IDs were unique, the report would lead directly to the bad guy. So you need to change the IDs of all the Roof 004 elements. You certainly can do this one at a time, and it will work.

Instead, use an Element Schedule to isolate the roofs, and correct the IDs.

Make a new schedule (Document -> Schedules and Lists -> Schedules -> Scheme Settings; Create New). The criteria:

For the fields, you just need 'ID', from the General heading:

This will give a schedule with all the roofs whose ID is not blank:

Make sure the 'Uniform Items' checkbox is off. If it's on, you'll get one line item for Roof 004, regardless of how many there are, defeating the purpose.

Now all you have to do is change all (but one) of the Roof 004 items to something unique. You can use numbers in the same pattern, as long as they aren't used elsewhere in the schedule, or you can add a, b, c, or something to the IDs.

Next time you run the 3D, section, or elevation window, you'll get the report again, but this time you can use the ID to find the specific element.

AC11 has a model view option to put the floor plan into reflected ceiling mode. It only works for objects, not regular elements (wish wish wish). I have several objects that take advantage of it.

This is the basic code you need to have a symbol draw itself differently in floor plan and RCP mode. The idea is that depending on the state of the switch, you set certain attributes, draw some things and not others, etc. Often, the shapes are the same, but the line switches from dashed to solid; stuff like that.

!! plnPen : Plan Pen (0=Match)
!! plnLT : Plan Linetype (0=Match)

The MVO dialog has three divisions. Options for Construction Elements concerns the display of real things, including openings, columns, beams, and markers. Options for Fills and Zones concerns how different categories of fills are displayed; turning cover fills on and off, e.g. Options for GDL Objects has only one item at the moment, the beloved Story Viewpoint Type, also known as the ceiling switch.

The keyboard shortcut to open the dialog is Cmd+9. I think the MVO dialog is pretty good about previewing the effects of most of the controls.

Rather than describe each combination, or heaven forbid build a table, I'll describe the A1/A2/A3 combination, then how the others differ.

I tweaked the Shape Tag object so you could have a masking fill within the polygon.

The intent is to show a solid white fill. To ensure wide compatibility, I've provided parameters for the fill and the white pen. Non-locals may want/need to change the defaults to their preferred solid fill and white pen.

The reflected ceiling plan is a universal drawing type that Archicad simply does not handle very well. We took a medium-size step forward in Archicad 11 with addition of the 'Ceiling Plan' model view option for GDL objects. This allows object developers to make objects that draw themselves differently whether the 'Ceiling Plan' or 'Floor Plan' setting is active. But this switch only applies to objects, and beams, slabs, etc. don't know you want a different linetype when they're overhead as opposed to on the floor. Hopefully, this switch will soon apply to all elements, and we will have dedicated attributes for 'Ceiling Line Type', 'Ceiling Pen', and 'Ceiling Cover Fill'. I have wanted this for a while.

In the meantime, the RCP still demands a lot of tracing of modeled elements. It's better than it used to be, but it's still one of the least unified drawings.

What shows:
• Walls
• Ceiling trim and finishes
• Ceiling fixtures including lights, fans, and mechanical fixtures
• Floor elements, including deck edges, stairs, counters; traced with a dashed line

A beam, or any other ceiling element, should be shown dashed in the architectural plan, because it's overhead. That same beam needs to be shown solid in the reflected ceiling plan, because then you're upside down looking straight at it. Using a conventional beam element, you would draw it with a dashed line in plan. But you can't show the same element in the RCP, because you can't make the beam draw itself solid. So you trace the beams with lines.

In Archicad 11, we have a model view option which allows objects, but only objects, to be drawn differently in floor plans and ceiling plans. This object is a simple wood beam that responds to this switch, so you don't have to trace it in RCP. There are limitations to using this instead of a beam element, see below. But for a simple beam such as a timber, you definitely should consider this object.

Size: Choose a dimensional lumber size, or choose 'Custom' and set the Depth and Thickness manually.

Slope: The usual roof slopes, or a custom angle. If the beam is sloped, parameters are available to control the Top and Bottom edge angles.

Roll Angle: Turns the beam around the long axis. If the beam is sloped this parameter is not used.

Plan Cover Fill: Just what it says. Turn it on and set the attributes, or don't.

RCP Attributes: The Pen and Linetype that will be used when the ceiling switch is on. When the switch is off, the object's 2D symbol will be drawn with the object's settings. In practice, the object should be set to use a dashed line, while the RCP linetype is solid. The pen doesn't really need to be different in most cases, but the option is there.

Pay no attention to where it says 'Transparent' when the pen is zero, and 'MISSING' when the linetype is zero. Those indicators are automatic and I can't get rid of them. In our case, zero means 'Match the object's settings'.

RCP Cover Fill: Just what it says; this fill will be used when the ceiling switch is on. This can give you some ability to show beams stacking in the ceiling, such as joists running over a timber beam.

Plan Lines: The symbol is a rectangle, with Start, End, Right, and Left lines. Any of these can be turned off, to make the beam meet a wall more cleanly in plan, for example. If the Roll Angle is non-zero, you will also have the option of showing the Roll Corner Line in RCP. This line won't show in the floor plan.

3D Pen: If this pen is non-zero, it will be used in 3D instead of the object's plan pen.

Start and End Miters: Turn these on and you can miter either end of the beam to meet other elements. The angles are graphically editable like any other mitered thing.

We have a special layer for elements we wish to see in plan and RCP, A Ceiling All. Use that layer for this beam.

This object is better than a beam element if you're just talking about the RCP. But there are plenty of ways it's not as good. One big disappointment is that you can't cross a pair of them and have them clean up in 2D and 3D. Another, beams can use custom profiles. A weird profile object has to be coded.

So, this object isn't a replacement for all ceiling beams. If it's a cased beam, you'll want to use beam element with a custom profile. If the beams cross, you need beam elements to make them clean up.

And if you're using real beams, you need to trace in the RCP. But, tip: If you have crown inside coffers, you might be able to skip out on the tracing and just let the crown objects (on the F Trim Crown layer) imply the beam shapes.

Another potential frustration is the case of a structural, visible timber beam. Normal structure beams are created with the Wood Beam object, which gracefully labels itself in the framing plans. The layer for these new ceiling beams can't do this, because I don't have a practical way to show the beam in all three plans, but the text in only the framing plan. A promising solution would be to create a label to refer to the beam, which could then show only in structure. Alas, here Archicad has stymied us again, because you can't show a label when the labeled element is hidden. And we can't show the beam itself because it's dashed. And I'm not putting the structure plans in ceiling mode, because I have no idea what the side effects of that would be.

For this case, model the beam using the RCP Beam object, and place another (Wood Beam) object on the +S Struct Note layer, with the Model parameter off.

With Drawing Title 10a you can:

• Set the Orientation of the title. You can have the title rotate to align with the Drawing (default), the Layout, or a Custom Angle. Use the Layout option to keep the title horizontal when you rotate a drawing. This is optional, and it's not always right. For example, if you rotate a wall section to fit on the sheet, the title should rotate too. I can't think of a purpose for Custom Angle, but it wasn't hard to put in there. If you do ever use it, the angle is graphically editable.

• Choose a manual scale from a list. Leave the field empty to use the drawing's true scale. This is usually correct. To show no scale text, choose 'blank' from the list. You need to set a manual scale for a scanned detail PDF; now you can choose it from a list.

A 2D symbol for plates, blocking, or other non-finish wood. This one replaces Lumber Continuous JAM81 and Lumber Blocking JAM8.

If you Use Standard Sizes, you can select the Board Size from the list. Better, you can stretch the symbol graphically, and it will snap to the standard sizes.

With Use Standard Sizes off, you can use any dimensions and stretch the symbol whichever way.

The Cross can be an X for continuous lumber or a slash for blocking.

There are separate pens for the Outline and the Cross.

The Fill switch turns the symbol opaque white.

Two objects (primarily) for cutting coved recesses into ceilings, using solid element operations. One's a circle, one's a rectangle. Guess which is which. The parameters of each are similar.

The fillet radius must be less than or equal to the height. The resolution of the fillet is controlled by the Fillet Facets parameter. For the disc, the Resol parameter controls the resolution of the circle.

You can turn the objects upside-down with Flip Z. I can't imagine many cases for doing so, but you never know.

In practice, your ceiling slab will be the target, and the object will be the operator.

The 11 version of these objects adds the ceiling switch-awareness that we've used previously in Soffit Cutter JM11 and Ceiling Line JM11.
