First of all, I would like to thank everyone for trying to help.

Your terrain is very large and you have many elevation points....  this may be a contributing factor to the issue.  Attached is a picture where I reduced the size of at the terrain.  I understand that this may be not what you want,  but it proves that you have things built correctly by CA and your computer may not be able to handle this size model.

 

BTW,  thanks for posting the plan,  it speeds up the process.

I have to use this terrain. I tried many programs, including AutoDesk Infraworks, Civil3D, 3DS Max, SketchUp with Instant Architecture and ESRI City Engine. We need to prepare terrain for houses, draw roads and fences. Then we open this model in Lumion and render 3D video animation. So far we got best results with 3DS Max (successfully completed 6 projects), but Chief Architect is the most intuitive program we found so far. Our new architect is using it and he told me that CA can draw roads. I tired it, and definitely CA workflow drastically decreases modeling time.

This is my PC config:

When I place fence on the terrain it sometimes follows terrain correctly, but often it "sinks" under.

 

Have you checked 'follow terrain' in the Stairs dbx?

Yes I have.

Yes I did (several times), and nothing changed.

I have a problem with CA precision regarding roads and fences. I've imported elevation points and generated terrain. When I place fence on the terrain it sometimes follows terrain correctly, but often it "sinks" under.

Similar problem happens with roads when I try to join two roads to form an intersection (curbs are misaligned).

Is there any way to fix this problem?

Sorry for my bad English.
