Hi.
I've created a terrain model from spot level from a referenced dwg file using graphic filter method. Triangulation was done smoothly. But I'm facing a lot of issue working with the terrain model. As you see in the attached screenshot, irrespective of the contour interval, no contour is being generated. I've tried this both by activating and deactivating the rules. There is no problem with displaying the triangles though. Kindly help.
I'm using Openroads Designer Connect Edition 2018 Release 2.
Are you talking about the line in the information category that stated 'Contours 0'? That line is telling you that there were no contours in the original data.
Change the feature definition to 'Existing Contours' and the calculated contours will display - also, under 'Calculated feature', you can amend the interval that you want them displayed.
The 'QuickStart for Terrain Display' training module may be useful.

Thanks Mark for looking into the matter. I have changed the feature definition/contour interval as you suggested. But after that too, the contours are not getting displayed. Screenshot is attached for your reference. Triangles can be displayed though. For the same topo data, previously i created tria model in MX and imported that tria model to Openroads terrain while using MX Roads SS4. That time I could change anything as desired. But this time, I attached the topo data(.dwg file) as a reference in Openroads and created the terrain model using graphic filter method. By using this approach I am facing this issue.
Just to check that the terrain has been created correctly using the DWG spot levels.
1. It is in a 3D file i.e. if you rotate the view, so you see the terrain in 3D properly?
2. Using (from the terrain tab) Analysis > Analyse Point - do you get the dynamic contour following your cursor when you select the terrain you want to analyse?
Yes. Terrain can be displayed properly in 3D and dynamic contour is also showing.
Another check - to eliminate the obvious.
1. Are the levels that the contours are drawn on turned on?
2. Even though the feature definition is called 'Existing Contours', does its settings actually the display contours?
Yes Mark. Levels are turned on. And as per settings, it should display the terrain. Even with same feature definition, and settings, everything is working fine in other dgn. I have tried to create terrain from same .dwg file, this time with Max Triangle length option, in case any problem happened during triangulation. But this time too, I'm facing the same problem. So, is it due to creating graphic filter from referenced file? For another project, when I converted the dwg to dgn and created the terrain model following same steps, I did not face any issue.
