Basic Subassemblies

Use these basic subassemblies to design assemblies.

Image	Subassembly	Common Uses
	BasicBarrier: A simple jersey barrier which can be adjusted in size and shape through a number of parameters. Default Tool Palette: Basic Subassemblies	Highway medians, traffic control during construction
	BasicCurb: Simple rectangular curb. Default Tool Palette: Basic Subassemblies	Any road design
	BasicCurbAndGutter: A simple curb and gutter in which the height and width of the curb and gutter can be adjusted through a number of parameters. The gutter slope can also be set. It is a "rigid" shape with no target parameters. Default Tool Palette: Basic Subassemblies	All road and parking lot curbing
	BasicGuardrail: Simple guardrail structure. Default Tool Palette: Basic Subassemblies	Any road design
	BasicLane: A simple lane with no subsurface courses. Available parameters control width, depth, and slope. It is a "rigid" shape with no target parameters. Default Tool Palette: Basic Subassemblies	Any road design where there is a constant lane width and no material volumes are needed
	BasicLaneTransition: Simple lane in which the width and outside elevation can be controlled through target parameters. Default Tool Palette: Basic Subassemblies	Turning lanes
	BasicShoulder: A simple shoulder with no subsurface courses. Available parameters control width, depth, and slope. It is a "rigid" shape with no target parameters. Default Tool Palette: Basic Subassemblies	Any road design where there is a constant shoulder width and no material volumes are needed
	BasicSideSlopeCutDitch: Daylighting that creates an optional flat or v-shaped ditch in a cut condition and a simple fill slope in a fill condition. Default Tool Palette: Basic Subassemblies	Simple daylighting
	BasicSideWalk: Simple rectangular sidewalk section with optional buffer areas on either side. Default Tool Palette: Basic Subassemblies	Residential and urban roads with sidewalks
