Build Terrain Outcomes

[WW2Architect]

I've seen somewhat random results occur when building a terrain. I am using Elevation Regions as the results of creating elevation splines was, well, interesting to say the least. 

 

With my elevation zones I have several objects that represent flat areas, slabs and retaining walls. It seems I get random terrain lines when I execute the Build Terrain or Camera view. 

1. I get a shark tooth effect on the high side of the retaining wall at 168" 

2. I get a shark tooth effect on the low side of the wall that is also a slab is also a part of an elevation zone defined at 132 inches. 

3. I see some random terrains in areas that I expect the grade to be consistent

 

Finally, when I attempted using elevation splines and even when using zones I've got some random towers and wells in the terrain generation, wild elevations I know I didn't accidentally input. I could not find the root cause of these. I could only back out my updates until they disappeared. 

 

See attached image.

 

PS. I've watched and followed the "Terrain and Site Plans: Learn the Basics" multiple times and in the video everything works perfectly. Seems that isn't always the case. 

 

PSS. Does anyone know a simple way to connect two splines together End-to-Start? When I was drawing the splines a few times I must have broken the link and couldn't find a way to get them to connect.
