ORD CONNECT 2020 Release 1 Update 8 10.08.00.88
I am trying to recreate an existing terrain model that we are currently using for a project. The current terrain was created by importing a .dtm file. The problem with the .dtm import is that all of the original .dtm features were assigned a feature style of Random Points. This creates an issue because we are receiving new survey that needs to be incorporated. We do not want to maintain a .dtm file and a terrain model. I have the original 3d base map file that coincides with the points from the .dtm.
I tried to create a new terrain model by using graphical filters. All elements imported fine. Panning around to compare the contours from the .dtm & the new terrain model I noticed some of the terrain model contours were inconsistent with the original contours. I realized that some of the triangulation was not correct. I updated the terrain from the graphical filter source data which fixed the contours associated with that filter (misc surface breaklines) but then other contours were wrong (roadway breaklines). Updating the roadway breakline graphical filter causes the misc surface breaklines to mis-triangulate.
I then started over by creating a new file from the project seed and merged the 3d base map into the file. Created an exterior boundary for the overall area using Create From Element. Then I tried using <Feature Management <Add Features. I turned off all levels in the file. I turned on my first level which is for sidewalks. I selected all of just over 8,000 elements. The import was successful. I turned the next level on which contained roadway edges and only has 3,200 elements. Everything was importing fine, but I received a message that states there are too many elements selected and could not be linked to the terrain. Do you want to continue with unlinked elements?
This is a big problem. I need the features linked to the terrain so that we can edit/remove/replace the elements in order to update the terrain model with the new survey.
I have been through this process several times trying to create features linked to a terrain. I continue to receive inconsistent results with importing elements. Sometimes I can import large amounts of elements without a problem then trying to a relatively small amounts of elements causes a problem.
How do I get around this problem?
Please see this forum post: https://communities.bentley.com/products/betas/openroadsdesignereap/f/openroads-designer-early-access-forum/128406/terrain-create-by-elements---performance. The element limit for terrains is 10,000. There is an enhancement to increase this: Enhancement 623863: [Terrain] Create Tm>Elements>Please Disable the 10000 Element Limits for testing to see if increasing limit is appropriate

So I cannot have an existing terrain model with more than 10,000 linked elements? My surface has 72,000 elements & that does not include the massive amounts of random points.. I realize that not all of them need to be linked, but I will still be over the 10,000 limit. How soon is the enhancement going to be incorporated? I think this is something that needs to be addressed ASAP.

Do you really need the overhead of linking 72000 elements to a terrain? How often does the survey data change? If it did not change that often, would it not be easier to just rebuild the terrain when needed?
As I stated previously, not all of those elements need to linked, but it will still be more than 10,000 elements that need to be linked.
No, we do not want to keep rebuilding the terrain. That has the potential to introduce mistakes not to mention the added time in doing so. We are still in preliminary design on a complex interchange. The project goes through residential areas with a lot of base map features. We have a lot of survey to be incorporated and there is potential for a substantial amount to be added.
Hi,
I'm currently facing the same problem, trying to create a terrain but I have 49,000 elements. I need the terrain to be linked.
Did you manage to resolve this issue and if so, how?
Thank you!
