Slab not actually cutting the site model?

[Abby Erwin]

I have been building a quick house model to use for planting design, and used a hardscape slab as the foundation.  This slab does not seem to have actually cut the site model, and there are strange chunks of the site sticking up around the building (massing model).  Am I missing something here?  I've tried checking and unchecking the "Cut the site model" option, as well as restarting the program.

 

Any help is appreciated!

Hi Abby, I think your trouble is coming from the hardscape in the existing class, that you put inside your massing model.  I have highlighted it in the attached image.  Not sure why you would do that, you can check the "draw floors" box in the OIP and simulate the slabs that way.  You have that hardscape set to act as a modifier, so it is pulling up the edges of the site model to meet it.  You'll need to set the site model interaction for that hardscape to "no site modifier".  Then update the site model.  I did see a second modifier in that same spot, you may need to remove that too.  You will need to turn on the Site->DTM->Modifier class to see it.
