Folks:
I have able to do some fairly consistent profile projections of inlet/ manhole SUDA nodes. However, some of the node projections come into the profile fine (manholes, in particular) while others (various inlets) seem to not have a correct projection; in particular, an inlet which is over 10' Lg. tangent to C/L which shows up as a bit over 4' wide in a profile cut/ run. How is SUDA looking at the nodes for what it considers to be their actual sizes for projection?

Mark,
Please provide screenshots and/or your data for us to reproduce the issue you are having.

Thank you, Holly.
Attached, you can see a simple drainage system layout, parallel to a particular centerline. The pipe lengths show up fine in the profile, but the structure widths do not. When applying the "Project Profile" tool, the projection lines do indeed represent the widths of the structures projecting to centerline, but you can see in the profile window that the widths are incorrect. Interestingly enough, the Engineering Profile shows the widths correctly.
The only structures which project consistently in my profiles are cylindrical manholes.As well, the issue seems to be random with larger structures showing up smaller than reality at times and smaller structures showing up larger than reality. But again, the issue is mostly random.
Thanks!
I have been unable to duplicate your results with my data set. If you send me your data, I can test with that.
Please try going to the Explorer > Drainage and Utilities Model > Profile Runs. Right click on the Profile Run that is displaying incorrect node sizes. Click Regenerate Profile Run. Does this help correct the display of the nodes?
There is a disconnect between hydraulic calculations and the physical model of the hydraulic system for structures. If you think about the cells that are used to model the structures; is the a cell for each box size? I haven't seen any workspace that has a correct box size for each structure. So while we have a 3d model, the level of detail of the model isn't very high. The calculated box size is not displayed graphically.
PEvans:
Well, I spent a great deal of time creating 2D and matching 3D models for all of our inlets, headwalls, and a custom Inlet Library and Conduit library to match these structures. I am still testing a few things before I send a file(s) to Holly, but there i literally no reason as to why these projections are not working correctly. As I am currently doing no hydraulic modeling for these structures, there would be no reason for the software to flip sizes based upon anything at all. All I am doing here is laying out some structures and projecting them upon a centerline profile; that is, any sizing is not relevant at this point.
Thanks for the input!
Holly:
I have done a regeneration of my profile run with the same results. Could you present to me an upload link such that you can analyze my drawing/ models? What information do you need from me? I am assuming just my dgn file?
You can upload your dgn here: https://bentley.sharefile.com/r-rbf5c3f0d22f499a8.
File uploaded, and thanks so much for your help! I feel like it has to be something "simple", but we will see.
Please upload the .cel file as well.
I uploaded a stripped version of the cel library only containing the structures of current interest. I feel that whatever maybe wrong is somewhat of a universal issue, so to speak.
I don't believe you have the correct cells that you want to use assigned to your Feature Definitions for the Nodes. For example....
In the dgn you sent me, the PR Inlet Cl Desc. 1 (6" Curb) Feature Definition has a cell called Top_Cl_Inlet_Des_1_6 assigned to the Top and Bottom_Cl_Inlet_Des_1_6 assigned to the bottom. Neither of these cells are within the .cel file you sent me. I edited the element template to point to a top/bottom cell from where you sent. I had to update the drawing my reconnecting the conduits to the nodes, but then the profile fixed itself. It seems that your Feature Definitions aren't operating like you'd like for them to. I recommend investigating your FD to make sure everything is pointed correctly.
I do have the correct cells assigned to my FD's; I just forgot to include those particular cells within the library that I sent to you... my fault- of course- on that one. All of the line-work from SUDA does indeed get projected to the profile, that is not the issue. The issue is that the widths (lengths along CL/ CRL) do not show up correctly with correct dimensions. I am provided three images which show the issue. Here, I have laid out some simple manholes and a couple of junction boxes, with the manholes being 4' ID, 5' ID, 6' ID, 7' ID, and 8' ID, and the junction boxes being 13' x 10'. The manholes should project to the profile as 4', 5' 6' 7' 8' wide, and the junction boxes as 13' wide. This is not what is happening. The projection shows 4', 5' 5' 6' and 7' with the junction boxes being 8' and 4.9213' wide. This number "4.9213" shows up quite often, especially when the structure is at the beginning or end of a run.
The first image is of the drainage along the centerline of the system. One may easily see by inspection that the widths of some of these structures is just not right. The second image is of a 3D cut along the centerline of the system. Here, one can see by inspection that the structures look absolutely great, with no errors to be perceived. The third image is of the system projected upon the CRL. The profile here is practically identical to the first image for the sake of inspection. Notice that the profile grid lines for the structure widths are correct as well as are the actual lengths of the conduits. SUDA seems to "understand" the actual widths of the structures even though they are not properly projected to these widths in profile.
This issue is critical to us here as SUDA only seems to fail utter perfection for us in only this single issue. I am uploading the cel library with the affected structures (yes, double checked this time), and another dgn for your inspection. If you find that the projections measure fine from your end, I would very much appreciate any ideas on what may be happening on my end. Right now. I am quite at a loss to explain what may be occuring here.
