Making the Transition from AutoCAD
Mechanical Desktop 6 is built on AutoCAD 2002 and uses many of the tools
you may already be familiar with. Because Mechanical Desktop is a parametric
modeling program, exercise care in using standard AutoCAD commands.
In the sketching stage, you can use any AutoCAD command to create the
geometry for your sketch. You can use AutoCAD drawing and editing tools
to edit sketch geometry after it has been consumed by a feature.
In general, follow these rules:
Use Mechanical Desktop dimensions. AutoCAD dimensions are not
parametric and cannot control the size, shape, or position of Mechanical
Desktop parts and features.
Use sketch planes and work planes to control the UCS orientation. Using
the AutoCAD
UCS command does not associate the current plane with
your part.
Do not use the command EXPLODE. Exploding a part deletes the part
definition from a Mechanical Desktop drawing.
Use the Assembly Catalog or the Browser to insert external part files into
drawings and externalize part files. Using the AutoCAD
INSERT, WBLOCK,
XREF, and XBIND commands could corrupt Mechanical Desktop data.
Use the Mechanical Desktop drawing view commands to create drawing
views. The AutoCAD
MVIEW command does not create associative views
of your parts.
Migrating Files from Previous Releases
In Mechanical Desktop 6, you can add more than one part to a part file for
creating combined parts. The first part becomes the part definition, while all
other parts become unconsumed toolbodies. You combine toolbodies with
each other and the first part to create a complex part.
To migrate parts from a part file that contains more than one part and was
created before Mechanical Desktop Release 2, you need to follow specific
procedures. See "Running the Desktop File Migration Utility" in the Autodesk
Mechanical Products Installation Guide on the product CD.
The File Migration Tool (FMT) is a component of Mechanical Desktop
Migration Assistance, an independent Visual Basic (not VBA) application
located on your product CD. The FMT migrates multiple files from previous
releases of Mechanical Desktop to the current format. You can install
Mechanical Desktop Migration Assistance during or after the installation of
your Autodesk mechanical product.
