Geometric Design Lab- Lab 02
Leg Centerline and Lanes using MicroStation

Students taking this course may print one copy of this document for their personal class use.

Objective:   Learn the basics of MicroStation required to operate GEOPAK by drawing a simple leg centerline and lanes.

Activity:   Start MicroStation and create a 2D design file "Z:\MicroStation\lab_02.dgn" using the seed file "Z:\MicroStation\train2d.dgn" ; Use MicroStation to Draw a Leg Centerline; Use MicroStation to copy the centerline 12 feet parallel both above and below the centerline for lane edges; Change the lane edge attributes to color green (color=2) and solid style (style=0); Place a landscape oriented rectangle centered around the roadway in 8.5" by 11" proportion (2070 feet by 1583 feet); Place the title "Lab Assignment 02" centered at the top and your name, class name, and assignment due date in the lower right at a text height and width of 75 feet; Compress the MicroStation design file and Save the MicroStation design file settings; Select the black and white laser printer as the default printer; Place a fence around the rectangle and print the drawing; Exit MicroStation; and Reboot the computer.

Background:   MicroStation is a Computer Aided Drafting (CAD) software package.   GEOPAK is an MDL application that runs on MicroStation.   Some knowledge of MicroStation is required to operate GEOPAK.   Intersection analysis begins by defining the geometry of the intersection.   A circular fillet is an arc of a circle that is tangent to two intersecting lines.

A.   Start MicroStation and create a 2D design file "Z:\MicroStation\lab_02.dgn" using the seed file "Z:\MicroStation\train2d.dgn".

B.   Use MicroStation to Draw a Leg Centerline.

B.1.   Set the element attributes.

B.1.a.   Select the Active Level icon (leftmost icon) from the MicroStation Primary Tools menu at the top and choose Level 1 (level=Level 1).

B.1.b.   Select the Active Color icon (next icon to the right) from the MicroStation Primary Tools menu at the top and choose the yellow color (color=4).

B.1.c.   Select the Active Style icon (next icon to the right) from the MicroStation Primary Tools menu at the top and choose dash-dot style (style=4).

B.1.d.   Select the Active Weight icon (next icon to the right) from the MicroStation Primary Tools menu at the top and choose weight 0 (weight=0).

B.2.   Place leg centerline.

B.2.a.   Place a 600 foot line at 30 degrees.   From the MicroStation Main Tool menu, select the Linear Elements palette (row 2 right icon) and open it as a tool box in the MicroStation View 1 window.

B.2.b.   From the Linear Elements palette, choose the Place Line icon (2nd from left on the top row) .   From the Place Line dialog box, select Length to be active (a check mark will appear), enter a value of 600 feet (enter the tab character to set the number), select Angle to be active (a check mark will appear), and enter a value of 30 degrees (enter the tab character to set the number).

B.2.c.   In the MicroStation Key-in field, enter "xy=5000,5000" plus a carriage return or the Enter key.   This entry tells MicroStation that the line should start at an x-coordinate of 5000 feet and y-coordinate of 5000 feet.

B.2.d.   In Window 1, press the Fit View icon (the 5th icon from the left) ; the line should be visible.

B.2.e.   Place a 600 foot line at 0 degrees.   In the MicroStation window, choose Settings -> Snaps.   If Keypoint does not have a check mark to its left then select Keypoint.   In the Inform Message field, should be displayed.   From the Place Line dialog box, select Length to be active, enter a value of 600 feet, select Angle to be active, and enter a value of 0 degrees.

B.2.f.   Move the cursor in Window 1 near the top-right end of the previously placed line and press the Tentative button.   In the Status Message field, "5519.6152, 5300.0000" should be displayed, a larger cursor should be positioned on the top-right end of the previously placed line, and the previously placed line should be highlighted in magenta (if this did not occur, choose Workspace -> Button Assignments and set the tentative button to the middle button and try again).   Now press the Data button to accept this tentative point.   In Window 1, press the Fit View icon ; both lines should be visible.

B.2.g.   Place a 600 foot line at 30 degrees.   From the Place Line dialog box, select Length to be active, enter a value of 600 feet, select Angle to be active, and enter a value of 30 degrees.

B.2.h.   Move the cursor in Window 1 near the top-right end of the previously placed line and press the Tentative button.   In the Status Message field, "6119.6152, 5300.0000" should be displayed, a larger cursor should be positioned on the top-right end of the previously placed line, and the previously placed line should be highlighted in magenta.   Now press the Data button to accept this tentative point.   In Window 1, press the Fit View icon ; all three lines should be visible.   Close the Linear Elements palette by selecting the "X" in the upper right corner.

B.2.i.   Place a 1000 foot radius fillet with truncate between the lines 1 and 2 and lines 2 and 3.   From the MicroStation Main Tool menu, select the Modify palette (bottom row right icon) and open it as a tool box in the MicroStation View 1 window.
