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. 

 

Best regards. Peter

1 + 2 .....try putting a Terrain Break in the middle of the Retaining wall set to a 0" transition size, ie no slope - might need to move it a bit close to one side or the other to eliminate the jaggies/spikes

 

3. chief will automatically try and smooth terrains the best it can but sometime it's a bit like fight an old style waterbed, push down in one area and it will poup in another , chief used to have a vid on that too.

 

Also make sure you don't ever let any of the elevation data, ie splines, regions, points touch each other , they will fight each other for control at that point causing spikes or dips etc. too help with that I make the line style for Elevastion Data orange and use a orange 95% fill in the regions which will show darker in in overlapping zones.

 

PS you are better postings questions in the Q+A Forum and adding your .plan file if possible (14mb max) for people to look at and help out with.
