High rod – low rod = 3.45. Once the Survey Data has been imported and linework looks good Update the Surface Point Group on the Prospector tab, then Rebuild the EG Surface. Contours 1' and 5' (Background) is set as the Surface Style. In Surface Properties… Definition tab, the Build Definition Option I set the Maximum angle between adjacent TIN lines to 130°. With the Old Bainbridge Rd project that eliminated the need for adding a surface boundary. Saved me a lot of time! When you still need to modify the surface boundary in Surface Properties… set the surface style to one showing the boundary. Select it then on the Design panel of the Modify tab select “Extract Objects”. Then set the surface style to “_No Display”. Select the boundary 3D polyline then on the Surface Tools panel of the Tin Surface: tab from the drop-down select “Convert 3D to 2D Polylines”. Select the boundary 3D polyline and you should now see grips at the midpoint of each segment. Hovering over one of these midpoints display a menu where you can select add vertex. This allows you to quickly add points to that boundary using grips instead of the pedit command. When finished right-click boundaries under Surface Definition and select Add… then Ok. Now change the surface property in Surface Properties… to something showing contours to see how it looks.

You will still generally need to add Breaklines. In Toolspace, on the Survey tab, right-click Figures => Create Breaklines. In the Breakline column the check box next to the figures that you want as breaklines should have been set by the Figure Prefix Database. Modify them if necessary then click OK to create the breaklines. In the Add Breaklines dialog box, enter a Description for the breakline operation, then specify the Type of breaklines, or specify the Mid-ordinate distance for any breaklines that have curved segments if applicable. Click OK.

Once the surface has been completed open the layer dialog, select the Layer States Manager icon, select the Plan layer state, making sure “Turn off layers not found in layer state” box is not checked click the Restore button. Only feature lines and nodes wanted in finished drawing are thawed, linetypes are set, and all remaining points are labeled for plotting.

The first step in creating an alignment is deciding on the geometry. The centerline of the right-of-way has the advantage in that it is easily labeled and reproduced in the field for construction layout. It’s usually available from the Survey section. Everything you do from here on references alignments so think it through carefully. From the Alignment drop down on the Create Design panel of the Home tab select Create Alignment from Objects and select the geometry near the start end. I used Name: Alignment – Road, Type: Centerline, Alignment style: Existing, Alignment label set: Major and Minor only.

From the Assembly drop down on the Create Design panel of the Home tab select Create Surface Profile. Select surface, pick Add>>, then pick Draw in Profile View button. Rename the Profile view inside the first <> then click the icon and make sure the counter starts at 1. I used Profile view style: Major Grids and HGP, Data Bands selected EG_FG Elevations and Stations and defaults for everything. Select Create Profile View.

Select Sample Lines on the Profile & Section Views panel of the Home tab and select alignment. Create Sample Lines – On Sample Line Tools from the Sample line creation methods (icon) drop down select By range of stations, then add others as needed. Hit enter when done.

Click Place Adaptive Simulation on the toolbar or ribbon. Pick the path element(s). If the pre-drawn path elements consist of Lines/Arcs, select the path elements in the desired direction of travel, and then click a blank spot in the drawing. If the pre-drawn path elements consist of a polyline/complex chain or an alignment, select the path element nearer to the start than the end.

After the path has been selected, the simulation displays in the drawing with the default Centered option selected. Click OK to place a centerline path follow turn simulation.
