Civil 3D Medians and Curb Islands made easy in CORRIDOR

Autodesk University was great again this year. My biggest regret was not meeting with every client that was lucky enough to be out there. I would also like to thank the clients that did hangout. First year that the CRAPS table thanked me for coming to AU.

I spoke for the 4th year in a row and the title of my class was AutoCAD® Civil 3D®: "Curbing" Your Enthusiasm. I presented Conditional corridors for driveways, ADA ramps and sidewalks. I also provide a SOLU-AROUND for medians. Below shows a small portion I presented about medians. I will provide the ultimate part about my class after this solu-around.

This method of creating medians was not practical until the 2012 version. In version 2012 we can add multiple baselines alignments to a single corridor and all assemblies show up together in cross section view. So why not create alignments from each island and use the corridor surface as the profile? This would be dynamic and update as the corridor changes. Unfortunately Civil 3D corridors will not accept the elevation from the corridor profile. Solu-Around, create a new surface called medians. Now paste the corridor surface into it.

·         Create a corridor surface

·         Create a surface called medians

·         Paste the corridor surface into the medians surface

·         Create alignment from the edge of pavement around the median

·         Create profile from median surface.

·         Create assembly using only curb attached to the assembly

·         Add the alignment, profile and assembly to existing corridor

 

I will post part of the AU class or recorded Solu-Around at ADSKSolutions.com I will provide

Intersection Design with ADA Ramps - Civil 3D

This workflow will utilize conditional subassemblies and automatically place ADA Ramps at selected locations. We will use the Intersection Wizard, draw a couple of polylines, set targets and apply a simple assembly set. The images below represent expected results once code set styles, default settings and custom assembly set have been established.

Download my custom assembly set.(XML File) The image below displays the Sterling Curb Return Fillet assembly that creates the ramps.

1.    Draw at least two alignments; create and design road profiles for intersection design.

3. Start the Intersection Wizard, set parameters. (offset, slopes, radius,etc)

4. Import Custom Assembly set

   5. Complete the wizard

6.    Draw polylines to represent sidewalk ramps.

                                              

7.    This step requires some knowledge of Civil 3D to completely understand the workflow (Solu-Around). Zoom to the assembly set that was imported into the drawing after completing the intersection wizard. Locate the Sterling Curb Return Fillets assembly. This assembly utilizes a conditional subassembly (horizontal targets). Select the intersection; locate edit targets in the ribbon. Select the one corner of the intersection and select target, locate Target Offset (ConditionalHorizontalTarget) select the polyline that represents the ramp. Repeat for the Target Offset below in the same dialog box and select the same polyline.

8. Ramp has been inserted into the corridor. These steps are not a solutions for all intersections or ramps, but a suggestion on how this can be approached. My second Solu-Around will be shown in Part 2. I will show how feature lines are utilized to design ramps. Build a surface from these feature lines and paste the new surface into the corridor surface for final grading.
