Exercise 1: Creating an Assembly with a Transition Lane

In this exercise, you will create a corridor assembly with transitions.
Create an assembly baseline
  1. Open Corridor-2a.dwg.
  2. Click Home tab Create Design panel Assembly drop-down Create Assembly  Find.
  3. In the Create Assembly dialog box, for Name, enter Transition. Click OK.
  4. When the ‘Specify assembly baseline location’ prompt is displayed on the command line, click a point in the drawing to place the assembly.
    The viewport zooms to the assembly baseline, which looks like this:
Add a lane subassembly
  1. If the Tool Palette containing the subassemblies is not visible, click Home tab Palettes panel Tool Palettes  Find.
  2. In the tool palette, right-click the Tool Palettes control bar. Click Civil Imperial Subassemblies.
  3. Click the Basic tab.
  4. Click BasicLaneTransition.
  5. In the Properties palette, under ADVANCED, specify the following parameters:
    • SideRight
    • Default Width14.0000
    • Depth1.0000
    • TransitionChange Offset And Elevation
  6. In the drawing, click the marker point on the assembly baseline.
    A lane is drawn, extending 14 feet to the right, with a slope of -2% and a depth of 1 foot.
Add a curb and gutter subassembly
  1. In the tool palette, click BasicCurbAndGutter.
  2. In the Properties palette, under ADVANCED, specify the following parameters:
    • SideRight
    • Gutter Width1.2500
  3. In the drawing, click the marker point at the top-right edge of the lane to draw the curb and gutter.
Add a sidewalk subassembly
  1. In the tool palette, click BasicSidewalk.
  2. In the Properties palette, under ADVANCED, specify the following parameters:
    • SideRight
    • Buffer Width 12.0000
    • Buffer Width 23.0000
  3. In the drawing, click the marker point at the top back-side of the curb to add the sidewalk and its buffer zones.
Add a ditch subassembly
  1. In the tool palette, click BasicSideSlopeCutDitch.
  2. In the Properties palette, under ADVANCED, specify the following parameters:
    • SideRight
    • Cut Slope3.000:1
  3. In the drawing, click the marker point at the outside edge of the outer sidewalk buffer zone to add the cut-and-fill slope.
Add a transition lane subassembly
  1. In the tool palette, click BasicLaneTransition.
  2. In the Properties palette, under ADVANCED, specify the following parameters:
    • SideLeft
    • Default Width12.0000
    • Depth1.0000
    • TransitionHold Grade, Change Offset
  3. In the drawing, click the marker point on the assembly baseline. A lane is drawn, extending 12 feet to the left, with a slope of -2% and a depth of 1 foot.
Mirror the subassemblies outside the right lane
  1. Press Esc to exit subassembly placement mode.
  2. In the drawing, on the right-hand side of the assembly, select the curb, sidewalk, and daylight subassemblies. Right click. Click Mirror.
  3. Click the marker point at the top-left edge of the transition lane to draw a mirror of the curb, sidewalk, and daylight subassemblies.
    The subassemblies are displayed on the left side of the assembly marker.
    The Mirror command creates a mirror image of the selected subassemblies. All the subassembly parameters, except for the Side parameter, are retained.
    Note:
    The parameters of the mirrored subassemblies are not dynamically linked. If you change a parameter value for a subassembly on one side of the assembly baseline, the change will not be applied to the opposite side.
    The finished assembly looks like this:
