3D constraint In assembly modeling, an associative link between two or more parts that controls their
locations relative to each other and to their placement within the assembly.
Assembly Catalog The means of attaching and cataloging local and external parts and subassemblies in
the Assembly Modeling environment. Use the All and External tabs to specify contents,
which can be instanced, copied, renamed, replaced, externalized, removed, localized,
sorted, unloaded, and reloaded.
assembly tree A graphical hierarchy that illustrates the order in which parts and subassemblies are
combined in the current assembly. The assembly tree is managed in the Desktop
Browser.
attach The act of connecting a reference file to the current assembly file. The attachment
remains with the current file after the file is saved.
definition All information about a part or subassembly, including its name, location, and
attributes.
detach Permanently removing a file as an external reference in an assembly.
external reference A part or assembly that resides in a file other than the current part or assembly file.
insert constraint Aligns center points and planes of two circles in a specified direction. Solves translation
degrees of freedom. Used to constrain a bolt in a hole, for example.
localized part Changes the definition of a part from external to local, severing the link to the external
file. Changes made to a localized part affect only the current part or assembly file; other
part or assembly files that reference the part are not affected.
mate constraint Causes a plane or axis on one part to be coincident with a plane, point, or axis on
another part in a specified direction. Removes a translational degree of freedom.
rename definition In the Part or Assembly Catalog, an attached external part or subassembly may be
renamed. The alias name is displayed beside the drawing name in parentheses.
scene A 3D orientation of an assembly that you can use to create a 2D view in Drawing
mode. You use scenes to provide exploded or assembled views of your assembly
without destroying the constraints.
trail In an exploded view, a line that shows how parts in an assembly are assembled.
tweak Adjusts the position of parts in an assembly scene to avoid overlap in some views or to
make some parts more visible.
