different blocks will be excavated. To display only excavations, turn this option on.
View > Hide > Excavations When activated, excavations are hidden.
View > Hide > Unused When activated, unused elements are hidden. Unused elements are
3D block surfaces or DD planes that are not used in the analysis. Such elements exist where a
fault cuts through an excavation, or where a material with a lower material number resides within a
zone with a higher material number (e.g. a dyke cutting through an ore zone).

this may change. To hide unused surfaces, turn this option on. Refer to

for additional discussion.
View > Hide > Translucent When activated, hidden surfaces as displayed translucent.
View > Hide > Show Errors Hide/display errors (when activated, show only element
errors). Note that this option can be used with the View > Hide > Translucent option.
View > Hide > Hide Errors Hide/display errors (when activated, do not show element
errors).
At the CAD stage the various colours indicate the following problems:
Purple - gaps have been found and filled, thus fixing this problem. This message does not
indicate an error and is given as user information.
Green - duplicate blocks have been found and deleted, thus fixing this problem. This message
does not indicate an error and is given as user information.
Blue - narrow gaps have been detected. These gaps do not indicate an error and are not
necessarily a problem, however if problems arise during the intersection analysis or BEM
analysis, these locations are the most likely causes. This message does not indicate an error
and is given as user warning.
White - edges that link the wrong way have been detected. Closed blocks must have all edges
linking in a consistent manner so that the inside and outside of a block can be consistently
determined. White edges do not satisfy this requirement. This message does indicate an error
which should be fixed before proceeding with the analysis.
Orange - edges that do not link to other edges have been detected. Closed blocks must have all
edges linking to one other edge to form a closed block. Orange edges do not satisfy this
requirement. This message does indicate an error which should be fixed before proceeding
with the analysis.
Yellow - edges that link to more than one other edge have been detected. Closed blocks must
have all edges linking to only one other edge to form a closed block. Yellow edges do not satisfy
this requirement. This message does indicate an error which should be fixed before proceeding
with the analysis.
Red - highlights Visco-Plastic zones with invalid hex shapes. In Map3D Visco-Plastic, plastic
zones are only permitted to have hexahedron shapes (4 corners at the top and 4 corners at the
bottom) or some degeneration of this shape such as tetrahedron.
At the INTERSECTION stage the various colours indicate the following problems:
Purple - a surface has been disabled due to an unresolvable contact. When the contacts been
various block surfaces was analysed, the way that this surface interfaced with another surface
could not be resolved so the surface was disabled and hence will not be used in the BEM stress
