Cosmetic Threads
Cosmetic threads describe the attributes of a specific hole so you need
not add real threads to the model. A cosmetic thread represents the minor
(inner) diameter of a thread on a boss or the major (outer) diameter of
a thread on a hole and can include a hole callout in drawings.
The properties of cosmetic threads include:
You can represent threads on a part, assembly,
or drawing, and you can attach a thread callout note in drawings. You
can add cosmetic threads to conical holes. If the conical thread does
not end at a flat face, it is trimmed by the curved face.
A cosmetic thread differs from other annotations
in that it is an absorbed feature of the item to which it is attached.
For example, the cosmetic thread on a hole is in the FeatureManager design
tree as Cosmetic Thread1 
under the Hole feature,
along with the sketches used to create the hole.
When the pointer is over a cosmetic thread, the
pointer changes to 
.
Cosmetic threads in part
documents are inserted automatically into drawing views. A thread callout
is also inserted if the drawing document is in ANSI standard. (You insert
thread callouts in the Cosmetic
Thread PropertyManager,
but they appear only in drawing documents.) Thread callouts are not used
in ISO, JIS, or other standards, but you can show them with Insert
Callout on the shortcut menu (see the next paragraph). To insert
cosmetic threads from assembly
documents into drawings, click Insert, Model Items and click Cosmetic
thread 
.
In drawings, Insert
Callout appears in the shortcut menu. If a cosmetic thread callout
is defined in the part or assembly but is not displayed in the drawing,
you can display the callout by selecting this menu item. A leader attaches
to the thread by default. The callout is a note.
If you add a cosmetic thread while working in
a drawing view, the part or assembly is updated to include a Cosmetic
Thread feature.
You can dimension both the circular cosmetic thread
and the linear dimension of the sides in drawings. You cannot dimension
cosmetic threads in part or assembly documents.
The visibility of cosmetic threads follows the
visibility of the parent feature. When you change display mode, add features
to the Show Hidden Edges list,
or hide a component, the visibility of cosmetic threads changes automatically.
You can
set High
quality cosmetic threads to check all cosmetic threads to determine
if they should be visible or hidden.
You can reference patterned cosmetic threads.

For straight tap and tapered tap holes, you can add cosmetic threads
in the Hole
Wizard.
NOTE: For tapped holes with
cosmetic threads created in the Hole Wizard, the hole diameter is the
diameter of the tap drill. For tapped holes without cosmetic threads,
the hole diameter is the outer diameter of the thread.
For shaded
display of cosmetic threads, click Options
. On the Document
Properties tab, select Detailing.
Under Display filter, select Shaded cosmetic threads.
To insert cosmetic threads:
On a cylindrical feature (a boss, a cut, or a
hole), select the circular edge where the thread begins. If the feature
is a conical hole, select the major
diameter. If the feature is a conical boss, select the minor
diameter.
You can also select the feature after
you click the tool.
