Surfaces

[Anonymous]

I have created 2 surfaces in the attached drawing (SG for Sub Grade and DG for Design Ground). There is also a 3rd surface being referenced (EG for Existing Ground).

I have also created a Wall Breakline and added it to the DG surface but for some reason the contours and triangulation looks weird in some places (very noticeable when you look where my building is. The Wall Breakline I created has the top being at my slab elevation and the bottom being 0.10m lower.

Have I done this wrong or can somebody see what is wrong?

I have attached a screenshot where the blue line is my building outline and the red markings are circling the oddities.

I have also attached the .dwg file (15524-SITE) and the file that contains the EG surface (16-0005 warner park sketch)

Thanks in advance Caddies!

Your DG surface has elevations as low as just over 1000m and as high as over 2000m. There are nine points over 2000m. Eliminate those and the surface looks fine.

I would check the others, too, if I were you.

Hmm, shouldn't be any over 2000 I don't think. Will have a look, thanks!

Ok, I looked in the points editor and didn't have any above 2000. They were all around 1040 except for a couple at 0 which I deleted. Got rid of the weird formation on the left side but the two over my building slab are still there.

Yeah, I couldn't figure out where those points are coming from, either, but you can eliminate them by setting your Surface Properties to exclude points above a certain elevation.

Where did you even see that there was points above 2000?

Yup, that did it! Thanks!
