Hello Team,

I have a nice video showing step by step how to create a site improvement for Takeoff (using line-string and making sure the properties for the surface sharpness is set to sharp and texture boundary)

But for some reason I am missing something. every time I click inside a boundary its flooding and filling the whole OG surface. The test file is attached, please let me know what I am missing here.

2nd question how I can convert multiple cad line to String line all together.

thanks in advance

The lines need to be a part of the surface that you are applying the Site Improvements to as well as having the property Sharp and texture Boundary.

  I am having the same problem when configuring simple subgrades and the line I am using as a site-improvement region is both part of the surface and has the property sharp and texture boundary and when the improvement is applied it still floods the whole surface region as essentially a total surface offset. Maybe I am overlooking something here.
  
  Also on another note I am having difficulty having surface cross-sections that are referenced by a corridor plotting to the proper grid. For some reason the vertical grid runs all the way down to zero even when all of the cross-sectional data is around elevation 600. I have gotten the plotting to work properly on another project, and believe I have all of the settings identical. Again any tips you could help me with would be greatly appreciated.

    I think your plotting problem is caused by your HAL not having a VAL that
    is close to your Design Elevations. If you dont have a VAL just a HAL then
    add a Vertical to the HAL and give it an elevation of something close to
    the center of your project elevation range. Let me know if that doesnt work
    - I have seen that personally and I am pretty sure that is your issue.
    
    On the first point - you need to check that the area is closed - if you
    have a Linestring that looks like it starts and ends in the same place, set
    the Autoclose setting on the linestring to make sure that it closes out. If
    there is a small gap between the start and end of an "Apparently Closed
    area the SI can flood out.
    
    The other time I have seen this is when you are applying SIs to areas that
    are bounded by multiple lines, and in some cases one straight line is
    intersecting an arc element. Because of the way that the Triangles form (By
    Chording the arcs), the line element may intersect the Arc Mid Chord. If
    that happens, while graphically the line looks like it intersects the arc,
    as far as the model is concerned it is not - so what I do then is "Break"
    the Arc at the end of the Line segment and then rejoin the now two arc
    elements back together again - now the surface will update and the end of
    the line and the spot where you broke the arc are now 100% in the same
    place and you will find that you SI will now work correctly.

In TBC v5 there is a new Macro Command that Converts Polylines / Cad Lines to Linestrings en masse

In prior versions you had to use the Elevate Lines using Text - put a piece of text that says 100.000 a long way away from the lines, use that piece of text to elevate all lines but with a very small offset tolerance - then no line will be elevated but all selected lines are converted to linestrings in this process
