Surfaces

use surfaces as construction geometry
use surfaces to modify a solid (replace face, cut with surface, up to surface)
create construction surfaces
create solids from surfaces
use Move Face (Insert>Face>Move Face) to offset, translate, or rotate faces. It will move a face and extend or trim adjacent features.
delete, trim, knit faces, and thicken the part to break a solid into a surface part and back into a solid again.
with most free-form parts you need to model in draft and cannot add it as a feature later
switch from surface to solid via delete face, thicken and knit surface
extrude to, cut to, cut with, or replace surface if you have a solid and a surface body.
create surfaces off parts to trim solids

make a copy of a face of a solid, use offset surface or knit surface
use Surface Push to deform surfaces of target bodies by pushing tool bodies into them
under Mirror, keep the Knit Surfaces option cleared if you're mirroring multiple surface bodies, and knit them together manually.
if you shell a part, better to create a filled surface, rather than a lofted surface with a singularity
do corner blends as a series of delete, trim, filled surface to remove small corners
use split entities on a trim line to control the trim boundaries for easier lofting between edges

use Tools>Sketch Entities>Spline on Surface to create a 3d spline constrained to a surface. You can use existing edges to set spline tangencies.
use imported geometry to create a solid, or to create a knit surface that can be used for other purposes
choose curve-to-curve deform deform complex shapes from initial to target curves. Use this for handgrips.
offset an existing solid surface by 0.00, extend it, then cut with that surface
use Delete Face to delete existing faces (say fillets)
use deform when evaluating design concepts of making geometric changes to complex models that would take too long with the traditional methods
use Boundary Surface on a four-side patch to control C2 in two directions
create a surface model for a master model, and turn it into a solid downstream
work with a Surface Master Model or a Solid Master Model
