Layer combinations

It’s a complex world.

Pens

A bit about the BDA pen tables for ArchiCAD.

Layer Lingo

NOMENCLATURE KEY FOR LAYER LIST
VESDView, Elevation, Section, Detailtypically sharing the same Layer Combination
2DTypically means "Plans", but often means "lines, arcs, splines, fills"a plan knows only X and Y
3DVESD drawings - more than just axon and perspectiveany drawing that knows about Z

Layers

PREFIX KEY FOR LAYER LIST
!Used once for A-grid, throwing it to the top of the list.
+Drawing or annotation, no model, printed
OOption layers. Create as needed to temporarily store options. When an option is selected, move the selected option's elements to the correct A-layers, and delete any remaining O-layers.
A, C, D, F, L, M, P, S, etc.Architectural, Civil, Demo, Finish, Landscape, Plumbing, Structural
VSpecific to visualizaton or rendering.
XSpecific to software processes, not printed.
ZSpecific to building or design processes, not printed.
SUFFIX KEY FOR LAYER LIST
no suffixGood for both 3d and 2d printing and modeling at any paper scale
-12, 24, 48, 96, etcShorthand for annotation layers unique to a particular paper scale.
12 = 1"
24 = 1/2"
48 = 1/4"
96 = 1/8" and so forth
-2A unique 2d layer, for plan output only. No 3d content.
-3A unique 3d layer, for VESD output only, not for plan.
NameWhat goes hereUsage Notes
ArchiCAD LayerNothing!Do not use
!-gridCenterlines, layout lines, regulating lines, calculations, gridUsually just the ArchiCAD grid object.
Usually printed.
This is an important layer in that it communicates design intent.
