BO BOUNDARY - selecting internal point to create a region/boundary
EXT EXTRUDE - extruding a shape to give it height/length
UNI UNION - combining two solids together
SUB SUBTRACT - subtracting one object from another




SETTING KEYBOARD SHORTCUTS
Choose Express > Tools > Command Alias Editor
 (create a personal shortcut, ex: psolid to become pso as personal shortcut)


SOLIDEDIT - editing an already created solid
     FACE
     EDGE


Start with basic primitive shapes
BOX
SPHERE
CYL CYLINDER
CONE
WEDGE
TORUS
PYR PYRAMID
PSOLID POLYSOLID



Choosing lines or plines to form a region vs. selecting internal point (BO).
REG REGION - selecting lines to define a region
(2nd option create lines to be a shape beside boundary)


Start creating walls immediately.
PSOLID - creating solid walls, set height, set width
     SET WIDTH
     SET HEIGHT



Create unusual surfaces by drawing a profile of your object.
REVSURF - revolve to create surfaces, use front/back view

Set the following:
SURFTAB1 - viewing of how many facets, how smooth the object looks = 24
SURFTAB2 - viewing of how many faces, how smooth the object looks = 24
 (1 is for REVSURF, 2 is for REVOLVE)
  1. SET VIEW TO FRONT VIEW
  2. DRAW A PLINE
  3. DRAW A SECOND LINE TO DEFINE AXIS OF ROTATION
  4. USE COMMAND REVSURF
    1. Select Object to revolve
    2. Select line of axis
    3. Keep default of rotation 0
    4. Set amount of revolution, up to 360

Create unusual forms by drawing a profile of your object. 
REVOLVE - revolve to create solid forms
SURFTAB1 - viewing of how many facets, how smooth the object looks = 24
SURFTAB2 - viewing of how many faces, how smooth the object looks = 24

  1. Create closed shape using PLINE and CLOSE the object.
  2. Use command REGION to select lines to form shape.
  3. Draw a second line to define axis of rotation
  4. Use REVOLVE command
    1. Select Object to revolve
    2. Select Object to use for rotation
    3. Set the revolution, up to 360
