Grading Object Infill Problem

261 Views, 1 Replies

I am creating a simple, and although it's large (100 million gallons), the grading object routine is relatively simple.  I have the inside crest of the berm and I'm grading down 40-50 feet.  Everything is fine until I infill the bottom of the basin and then the infill line around the perimeter of the bottom has two points that are way below the actual bottom, like another 100+ feet.  The two points are on opposite sides of the basin so obviously it throws off the whole resulting surface and causes earthwork calculations to be invalid.  

 

I've tried various sizes and shapes, having the crest feature line both "open" (with a tiny gap) and "closed", straight and arc shapes for the crest, grading to elevation and to relative elevation, and probably more.  This problem seems to appear in each scenario.  Any help?

Why not dump the Grading Object.  It appears you already know what you want.  Make it out of Feature Lines.
