terrain retaining wall with flat bottom?

Terrain retaining wall bottoms seem to follow the curve of the terrain on the low side of the wall.

 

Is there a method to show a horizontal bottom. I am trying to show it in elevation view and it currently looks like kind of ugly. I tried a normal wall but it has a flat top

 

 

Two of them are shown below. bottom one shows the issue:

I rarely use retaiing walls because of the top / bottom control issue. Instead I use a terrrain break (2" transition distance, centered on wall) and I almost always use a 3d solid for the retaining wall. This provides me with stable control without ever having to 'fight' an automatic height. It also gives me more control over the ret. wall display in all views. More control, saves time.

I was pondering this, but then the top of the wall will have to be conformed to follow the terrain? But given I suppose most times this will be flatter, easier

 

I'm not that good with the polyline tools, but maybe an option is to create a fence, or line or something beneath the terrain retain wall, and invoke one of the CAD/3D solid tools to have to extend to meet the line?

If you are still using retaining walls make sure the default top and bottom are selected as if you have adjusted the wall top or bottom  chief will no longer auto adjust there top or bottom positions to match the terrain

 

It looks when I made the, change to the bottom, only the bottom check box deselects. The top remains checked. If I move the terrain down say 20", the top still moves with the terrain but the bottom does not. see below

 

But is there a better option? A solid would needs its top changed to match the terrain, and in thinking about it maybe that is better as one could step the solid like a real wall,  and if the terrrain moved up and down as a whole, the solid would move with it, maintaining the bottom of the wall.

 

...per usual... a couple options...each with their benefits and drawbacks

A solid would need the top adjusted to be relatively close to the terrain, depending on retaining wall type. What I was referring to was a 3d solid that represents a concrete retaining wall, formed with either:

  • a straight, consistently sloped top slightly higher than the high side of the terrain
  • a straight stepped top, formed in even increments suitable for concrete form work 

What I was not referring to is a concrete wall with an undulating top and bottom as determined by Chief's terrain modelling characteristics. I prefer something useful for my modeling and my builders. I also don't care about Chief adding a footing to my retaining wall unless it is required for the particualr wall construction...which varies by builder preference, jurisdiction structural requirements, overall retaining wall height, retaining wall location relative to property line, structural engineering (if needed), etc. And for retaining wall con docs, I'm just going to be using one of my cad details, already completed or ready to duplicate for a unique application.

yes, that is more real life, I understood it to be a 3D solid, which is why I commented probably the better option.

Is that what you want

I dont need a footing, but that is interesting. Did you just pull down the footing (if so I suppose the footing could be set to the same width). Ultimately what I was trying to do was while I was adjusting the terrain, the wall would come along with it, but keep the bottom (below the terrain flat). Ironically in the end for this project, the terrain region was almost flat, so a 3D solid with a terrain break would have worked just fine.

 

But it did get me thinking for the next one how could I do it dynamically.

For this one I just put in a CAD box masking the ugly below the terrain terrain retaining wall, and for the moment, have yet to step the bottom. But I had to send it off Thursday so it went like that.. (...the workaround 3rd option..which is not my preference going forward)
