Useful Rhino 7 commands to work with engineering models

Rhino has very large set of commands to operate on 3D geometries. The full list can be found here: Command Quick Reference | Rhino 3-D modeling

The pdf document attached here outlines Rhino commands that are very often used by Itasca engineers when creating, modifying, and/or cleaning various types of geometries to prepare them for surface and volume meshing with Griddle 2.0.

If you often / heavily use other Rhino commands (not included in the list) to prepare your models for meshing, consider sharing information about them in this topic.

Thanks for the great list.
Further useful commands:

SelBadObjects: Selects any “bad objects” which can result in problems during meshing later. Read about bad objects here: Fixing Bad Objects [McNeel Wiki]
Grasshopper: Visual programming language and environment, useful for people that might not be very well versed with python (or other programming languages you can use in Rhino).
Invert: Inverts the entire selection. Very usefull to hide everything but the object you are currently working on
FillMeshHoles: Next to “FillMeshHole”, tries to fix all holes in a mesh. Use with care as sometimes holes are not filled as desired
DeleteFaces: Deletes a mesh face. Can be used instead of “ExtractMeshFaces” and delete

_VolumeCentroid: to create a center point of the bounding box created around an excavation that requires analysis in ITASCA software.
_ScaleNU: to scale up the bounding box created around the excavations of interest.
_ExtractPt: to create and extract 8 points at the edges of the bounding box required for setting up a boundary for you to assign a constitutive model like in the snapshot below.
