To Create Standard Cosmetic Threads
1. Click > > . The Thread tab opens.
2. Click
Standard Thread to use standard series and diameter.
3. To select a surface to thread, click the Placement tab, click the Threaded surface collector, and then select a surface.
4. To select the thread series, under
Hole/Thread, next to
Thread, select a series:
◦ For cylindrical standard cosmetic threads:
▪ UNC (Unified Coarse Thread) or UNF (Unified Fine Thread) —Sets the number of threads per inch and the Imperial system of measurement.
▪ ISO (International Organization for Standardization )—Sets the pitch and the metric system.
◦ For conical standard cosmetic threads:
▪ NPT (National Pipe Thread Taper) or NPTF (National Pipe Taper Fuel)—Sets the number of threads per inch and the Imperial system of measurement.
▪ ISO_7 (International Organization for Standardization )—Sets the pitch and the metric system.
5. To select the thread size, under
Hole/Thread, next to
Thread size, select a size.
6. To define the start of the thread, perform one of these actions:
◦ On the
Thread tab, under
Depth, click the
Starting surface collector, and select a reference (plane, surface, or quilt).
◦ Click the Depth tab, click the Start thread from collector, and then select a reference (plane, surface, or quilt).
An arrow appears indicating the direction of the thread creation.
7. To flip the thread to the other side of the start reference, click

on the
Thread tab.
8. For cylindrical threads, to set the thread depth (distance from the start reference), on the Thread tab, next to Depth, select one of the following options:
◦
Blind. Type a depth value in the box.
◦
To Reference. Select a surface, plane, curve, axis, vertex, point, or quilt at which to end the threading.
9. To change a parameter value, click the Properties tab, and then click a cell in the Parameters table.
10. Click
OK.
