Hello!

I have a 3D block where I have simulated the 2015 Nepal earthquake (see 1st picture). The earthquake was simulated along a fault plane located within the 3D block. The fault plane is defined by x,y,z point data (see 2nd and 3rd pictures). The fault plane is not planar.  
Using Delaunay2D I am able to make a plane out of the point data (see 4th picture). I would like to slice/cut the block using this plane but am struggling to do so. Is this possible? The 5th picture is the spreadsheet view for the MergeBlocks and Delaunay2D layers.

Thank you for any help you can provide!  
Michelle

The simpler way is to manually allign a slice plane with your plane. You can do that with the shortcut `P` and `N`.
