Civil Cells

I created my own civil cell for the first time, and everything seemed to work right when I created it. But when I went to place it for the first time nothing happened. I selected my new civil cell and clicked on the right reference elements and the EP lines from the civil cell showed up. But when I clicked "accept to place civil cell," nothing happened. Can someone please take a look and let me know what I'm doing wrong? I included a PDF that shows the steps I'm taking to try and place my civil cell and I also included my dgnlib file that has the civil cell I created so you can look at that also. Any help would be greatly appreciated.PDFKH.dgnlib

  • It appears that the vertical profile for the approach road is not really attached to the civil cell properly.  When I open the Civil Cell DGNLIB and test the horizontal geometry by dynamics by moving it around to test the connectivity the Civil Cell in the DGNLIB seem to follow along as you would expect.  When I display the profile model for the side approach road and change the slope or elevation of the profile element the Civil Cell does not dynamically follow along as you would expect.  If you look around in your design 3D model you may find that the civil cell 3D graphic model is there just not where you are expecting to see it i.e., attached to your geometry, because it seems to not be entirely connected.

    Was the GeomBL4 linear Geometry Profile generated as a profile by slope from element and with an offset and slope of 0.0 from the side road approach geometry? it appears to be defined as profile from absolute elevation 100. This GeomBL is the CL Linear geometry used in your approach side road civil cell model.  Note that is has set elevation of 100.

    Looks like the GML match line geometry was created using the "Profile by Slope from Element" that same method should be used on the CL and EOP(s) for the approach road.  This Mathcline GML is the profile properties of you matchline note that the geometry is a 0% slope and 0 offset from a "Reference Geometry" i.e. in this case main line edge and appears to work as it should but the overall civil cell does not really resolve as you would expect because of the hard coded in elevations.

    Could likely fix this by generating and setting the appropriate Vertical Profile geometry active. Not sure if the Pavement Terrain would need to be remade.  I think the Element Templates on the side slopes should reprocess attached to a new active profile element.  There is a number of geometry features with the Name GeomBL, if would be helpful to name each element specific to its application this would help in setting up.

  • I opened the DGNLIB dropped the civil Cell, created a new Profile element for the CL of the Drive using the "Profile by Slope from Element" (0%, 0 offset) set this new profile active, deleted the original, then remade the Civil Cell and it worked.  So really on the Drive Centerline profile element was the issue.

  • I'm really sorry, but I'm still struggling. I tried to create a new CL profile using "profile by slope from element." But now it won't let me click on my reference elements when I try to create the civil cell. Is there any chance you could send me a video or some screenshots to walk me through what you did to make it work? I apologize, I'm pretty new to OpenRoads and this is the first time I've used civil cells. 

  • I created another one per your instructions, but I'm still having the same issue. When I try to place the civil cell, it walks me through the steps and after I "click to accept civil cell" nothing happens. I've attached the new DGNLIB. Can you please take a look when you get a chance and let me know what I'm doing wrong?

  • Sorry, use this DGNLIB instead. I didn't label the reference elements to click on in the first one. This one should be less confusing.
