Retaining Walls Not Working With Imported Elevation Data?

[tandrasz]

Hi, 

 

I'm new to this. I'm using Chief Architect Premier X7. I have imported perimeter and elevation data from a DWG file. It looks correct in the Perspective Full Overview, however when I try to draw a retaining wall all I get is something that looks like a stripe of concrete on the ground (attached) - the terrain does not get broken.  In a new plan with perimeter and elevation lines created manually retaining walls work as expected. 

 

What am I missing?

Here is my plan:

The plan you posted has no retaining wall

[tandrasz]

It has, but it looks like a U shaped stripe on the surface - like in my screenshot. Try creating one in that plan.

You need to adjust your terrain elevation data like it needs to be different on each side of the retaining wall so break your elevation lines on the lower level area and adjust the heights as needed

@dshall - sorry Scott - I posted the original plan - without the retaining wall. 

@mark3D - thanks Mark, I will break elevation lines.

......I will break elevation lines. 

 

Elevation lines do not need to be broken.  If you use an elevation region,  that elevation region will override the elevation lines....  much quicker

Thanks Scott! I'm getting much better results with the elevation region, but I still must be doing something wrong. Here is the screenshot of mine (lower) vs Mark's (upper):

 

 

Mine has these rugged terrain irregularities, while Mark's is smooth.

Move your elevation region UNDER THE WALL BY ABOUT 3 inches, that should take care of irregularities.

That worked great!

 

 

Now, I just need to figure out how to convert the elevation region square into a polygon, so I can get rid of the up bump in the bottom right  corner.

Thanks - broke the right border at the start of the retaining wall and then made the shorter part almost zero length.
