used because they require you to locate the model manually, which can
be difficult without a common reference point in both files.
The automatic options are more commonly used, and each has a specific
function:
Auto - Center To Center
This option links the file from its center
point to the center point of your file. The center point is determined
by the location of the model objects within the file. This option
should be avoided unless you and your consultants have a
coordinated center point and the makeup of the model will prevent
that point from changing.
Auto - Origin To Origin
This is the best option to use unless a
shared coordinate system is required. The origin of the linked file
will not change if the model changes size or shape, or even if
building geometry is moved or rotated, so you will be able to stay
coordinated with the building when major position changes occur.
Auto - By Shared Coordinates
This option should be used when
a project requires that common location coordinates be used. This is
most commonly used on projects that have multiple buildings
because it enables you to keep the relationship between buildings
coordinated. If you link in a file that is using shared coordinates, you
can use the same coordinates for your file.
Be careful when linking in a Revit file because the Auto - Center To
Center option is the default. Forgetting to change the option could
result in a serious headache further along in the project, because we
know that architects
never
relocate the building, right? Make it a
habit to use the Auto - Origin To Origin option, unless shared
coordinates are required.
