4.2.4.4 Male Thread (ger. "Außengewinde")

In this exercise you'll learn about the feature Male Thread. It is used for adding a thread to the mantle of cylinders.

Open the model cylinder, if you previously created it, and save it as male_thread according to the naming convention. Otherwise create the model male_thread and add a cylinder with the following dimensions to it:

Dimension	Value [mm]
Diameter	20
Height	50

Symbolic thread

symbolic thread

Select the featue Thread

Insert-> Design Feature -> Thread

detailled thread

The window Thread pops up.
Select Symbolic and highlight the cylinder's mantle.

The necessary values for the thread are calculated automatically, you just have to specify its lenght and enter a starting point. In this case enter 20mm.

Now click Select Start and select the flat surface on the right.
If the thread's axis points into the wrong direction, you can switch directions by clicking Reverse Thread Axis

Confirm by clicking OK.

Confirm again by clicking OK.

The thread should now be represented by a blue dashed line on the cylinders mantle.

Now delete the Symbolic Thread and create a Detailed Thread using the same method. Observe the difference. For modeling there is no difference, but the CPU load is increased for detailed threads. (refer figure "symbolic thread") and (refer figure "detailled thread")

You can also create a female thread using the same method. Anyways, using the feature Threaded Hole is way easier. You should always prefer using threaded hole for creating symbolic female threads if you're not explicitly advised to create a detailed thread.
