Why does DTM site model crop always do this to me?

[Christiaan]

Any ideas how to fix this? Area in red shouldn't be visible.

can you post the file?

@ChristiaanHi is your model set to triangles or smooth mesh?

@Christiaan, also, is there a site modifier boundary object, encompassing the modifer? I think its called Grade Limits now.

Indeed it is. Only happens on this mode.

Changing yours from mesh to extruded contour seems to make it behave as it should.

 

I tried pasting the site model from one of my current projects into your file. Then I copied your crop object and applied it to my site model.

 

It seemed to work OK on mine , didn't produce the same result as yours - whether in mesh or contour mode.

 

Fiddling with yours, I found that offsetting the crop object inwards by 1000 made the messy bit disappear. I think there's something it doesn't like about the crop object being outside the extent of the survey data. I've a feeling I've come up against something like this in the past.

Yes, I think you're spot on. That crop is the boundary of the site so I think I'll just add some interpolated levels around that line. Thanks for spotting that.

Hmm, can we not mark a post as 'solved question'?
