Creating 3D threads
You can create threaded holes, insert threaded cylinders (used often as threaded ends of shafts) or create a thread at an outer cylindrical surface. If the current units are millimeters, you can select threads according to ISO (metric threads). If the units are inches, the threads are selected from list of Unified National Screw Threads (according to ANSI). For more information, see Threads.
This section of the tutorial shows you creation of a thread in the part used in the assembly example.

2D drawing in 3D, creating 3D sections
In 3D, you can draw a profile further used for extrusion or rotation to create a new solid. Such a solid is pre-inserted into 3D space according to profile’s location. This method can be, for instance, used for creation of a solid used as a section tool (like in this example). For more information, see 2D Drawing in 3D.
Selecting a drawing plane
Location projected from 3D into the drawing plane
2D was switched to “Ortho” mode. Outline of the section tool is created right according to an existing 3D solid. To define profile’s location, use the projection of 3D points – here is the projection of a circular edge center (intersection of axis of the hole and the drawing plane, more exactly). The profile is created as a multi-line and trimmed with the function creating a corner.

The thread was redrawn with the function “precise rendering”. Optionally, you can turn on drawing of the thread helix at threaded surfaces during the precise rendering.
2D drawing from 3D containing sections and threads
If a 2D drawing is created from 3D views with threads, the threaded surfaces are redrawn according to the current configuration. The configuration is available in the 3D export dialogue window. This example shows 2D creation of all outer or inner threads’ diameters according to ISO standards.
Active 3D sections are exported into 2D as cut solids. If the particular export is inserted into a list of exports and if the 2D creation is repeated, the corresponding sections are turned on or off the same way as they were switched during the first export creation.
3D view export definition
Front, top and left views were exported separately. Before the left view export, the section was switched off. The exported views are positioned at intersections of construction lines in 2D drawing area.
