ƒ ƒ

By using Precision Input Commands, 1st select a Starting point by clicking this button. Click on Intersection point of Cross lines on AutoCAD drawing, and press enter.

ƒ ƒ

Now have to construct cross section by “Precision Inputs”. The commands have to put here.

ƒ

These are the commands available to construct the typical section. Type the command on the second line and hit the Enter key. The window will ask you for the information needed based on the command. Keep using the Enter key, do not close this window. The typical section has to be created in a continuous way beginning at the crosshair point on the drawing. You have to draw only half of the section. RoadCalc can create a mirror image for the other side.

Option Absxy

Type A

Function This allows you to place the breakpoint using the values for an Absolute X and Absolute Y, referenced to the cross-hairs on the CAD screen.

dXdY

XY

dXS

XS

This allows you to place the breakpoint using the values for a Delta X and a Delta Y from the last breakpoint. This allows you to place the breakpoint using the values for a Delta X and % Slope.

dXH

XH

This allows you to place the breakpoint using the values for a Delta X and H/V Slope.

dXV

XV

This allows you to place the breakpoint using the values for a Delta X and V/H Slope.

dYS

YS

This allows you to place the breakpoint using the values for a Delta Y and % Slope.

dYH

YH

This allows you to place the breakpoint using the values for a Delta Y and H/V Slope.

dYV

YV

This allows you to place the breakpoint using the values for a Delta Y and V/H Slope.

Reset Pen

R

This starts the precision input command over. This will leave segments that have just been drawn and allow you to start from a different breakpoint.

Undo

U

This removes the previous segment added and positions the cursor on the previous breakpoint. This option is only available after a segment has been placed. It is not available in the middle of drawing a segment.

eXit

X

This stops the precision input command. Only available after a segment has been placed. Not available in the middle of drawing a segment.

PT Code

Use

-6 through -3

These codes are used to denote the four Superelevation Limit points on a divided highway typical section that follow the same rules as the 2 PT Code. They produce subsurface superelevation like the 2 PT Code.

0

This is used to denote a point on a cross-section that is not assigned to any special properties.

1

This code is used to represent the point on the typical section that is controlled by the Centerline Alignment and Centerline Profile.

3 and 4

This code is used to denote the Toe of Foreslope and Toe of Cutslope or where a ditch segment begins and ends. It is used during the Run Design command when a width controlled slope or a R.O.W. controlled slope is processed or when the Fill Ditches toggle is on.

10

This code is used to denote the outside top of the shoulder. When this code exists, it tells RoadCalc where to check for rollover, if this option has been specified by the .

1000 and 1001

These codes represent the left and right catchpoints (or daylight points) respectively.

ƒ

Example, to draw the following cross-section: ƒ 2-lane undivided highway ƒ 3.6 m lanes, 2% crown ƒ 3 m paved shoulder, 4% slope ▪ 1.5 m foreslope, H/V: 3/1 ƒ 0.5 m ditch

ƒ

ƒ

ƒ

ƒ

Start by clicking the moving crosshair to identify the starting point of the typical section on the drawing, type 1 for the PT code and hit Enter key. This code will establish the centerline of the alignment. For the next point, type dXS and hit Enter, type 3.6 and hit Enter, type -2 and hit Enter, type 6 and hit Enter. This will draw a line 3.6m wide with a -2% slope. The code will identify the end point as the end of the pavement. For the next point, type dXS and hit Enter, type 3 and hit Enter, type -4 and hit Enter, type 10 and hit Enter. This will draw a line 3.0 m wide with a -4% slope. The code will identify the end point as the end of the shoulder. For the next point, type dXH and hit Enter, type 1.5 and hit Enter, type -1/3 and hit Enter, type 3 and hit Enter. This will draw a line 1.5 m wide with a 1/3 down slope. The code will identify the end point as the left side of the ditch.

ƒ

ƒ

ƒ

ƒ

For the next point, type dXdY and hit Enter, type 0.5 and hit Enter, type 0 and hit Enter, type 4 and hit Enter. This will draw a line 0.5 m wide with no slope. The code will identify the end point as the right side of the ditch. For the next point, type dXH and hit Enter, type 1.5 and hit Enter, type 1/3 and hit Enter, type 0 and hit Enter. This will draw a line 1.5 m wide with a 1/3 down slope. For the next point, type dXdY and hit Enter, type 0.5 and hit Enter, type 0 and hit Enter, type 4 and hit Enter. This will draw a line 0.5 m wide with no slope. The code will identify the end point as the toe of the cut slope. To draw the pavement, reset the start point by typing Reset pen and hitting Enter. You can draw in AutoCAD a line that is 0.7 m in length to identify the new start point. to erase it later. Click on the moving crosshair to select the end of this new line as the depth of the pavement.

ƒ

For the next point, type dXS and hit Enter, type 3.6 and hit Enter, type -2 and hit Enter, type 0 and hit Enter. This will draw a line 3.6m wide with a -2% slope that will represent the bottom of the pavement layer.

ƒ

For the next point, type dXS and hit Enter, type 3 and hit Enter, type -4 and hit Enter, type 0 and hit Enter. This will draw a line 3.0 m wide with a -4% slope.

ƒ

For the next point, type dXdY and hit Enter, type 0 and hit Enter, type 0.7 and hit Enter, type 0 and hit Enter. This will draw a line 0.7 m vertical line. Make sure the line close the pavement area. The left side of the pavement area should be open to reflect that it continues to the right side.
