Terrain - how to force it to not do a curved fit between elev data

[brian-sdesign]

Is it possible to get the terrain object to do a straight line fit between elevation data points?

[Richard_Morrison]

Yes, but you have to put THREE closely spaced elevation lines at that elevation.https://www.chiefarchitect.com/support/article/KB-00574/how-chief-architect-interprets-terrain-lines.html

You can also try using terrain breaks and elevation points.  Just make sure to only use a single elevation point between each terrain break

I might be interpreting your question wrong but I think the simplest way to do this is opening the terrain DBX and setting the terrain surface smoothing to "linear".

I believe Javatom is correct.

Michaels way will give you a stepped terrain with level benching.

 

The OP asked for straight lines between the elevation points, not level lines - unless he wrote incorrectly.

Yeah, I could be totally off-course.  I may have misunderstood the question.  Wouldn't be the first time.

Linear is what I want but it does not give the expected results. I have about 5 terrain data lines all parallel and instead of straight line there is a small vertical jog up and down around a couple of the elevation lines. I just ended up adding a bunch more data lines and sticking with the medium curve fit.

No simple way. You'll need to grade in between your main established points using the grade percentage in between. Easy on a rectangle lot, a bit more work on an irregular lot.

Just replic ate your established grade points (separately)  using the correct x,y,z, info and you'll have it. In my screenshots the established data points are metric which makes it way more fun. One less step if you're in imperial...I add elevation points every meter.
