Cosmetic Thread Parameters
The following table lists the parameters that can be defined for a thread at its creation or later when the thread is added.
On the Thread tab, click Properties, and then in the Parameters table, click a cell to change its value.

Value

Description
|
|---|---|---|
|
MAJOR_DIAMETER
|
Number
|
For standard threads, equal to BASIC_DIAM in the hole table. For internal simple threads, the thread diameter. For external simple threads, the surface diameter
|
|
MINOR_DIAMETER
|
Number
|
For standard threads, equal to TAP_DEC in the hole table. For internal simple threads, the surface diameter. For external simple threads, the thread diameter
|
|
THREAD_HEIGHT
|
Number
|
Thread height (used for conic surfaces)
|
|
THREADS_PER_INCH
|
Number
|
Threads per inch (1/pitch)
|
|
PITCH
|
Number
|
Distance between two threads
|
|
FORM
|
String
|
Thread form
|
|
CLASS
|
Number
|
Thread class
|
|
PLACEMENT
|
EXTERNAL/INTERNAL
|
Thread placement
|
|
METRIC
|
YES/NO
|
Thread is metric
|
Either THREADS_PER_INCH or PITCH is displayed, depending on the following logic:
• If the threaded surface belongs to a standard hole, then for internal threads, the used hole table determines which parameter is displayed.
• If the threaded surface does not belong to a standard hole, then the diameter is compared to the values in the hole tables. If the value matches a value included in a hole table, then the corresponding table determines which parameter is displayed. If no value is detected in the hole table, then the current unit set and the METRIC thread parameter value determine which parameter is displayed.
You can manipulate thread parameters as you can manipulate other user-defined parameters. Click >
