Threading

 

 

 

 

This command creates a threading on the cylindrical faces

 

Creation stages / Use:

 

Click the icon or select Shape > Threading... from the drop-down menu.

 

  1. Select the cylindrical face to thread.

  2. Select the original plane to determine the start of the threading.

  3. Determine the different threading parameters

  4. Validate the command with the button

 

 

To be able to create threadings, you must reference a library containing the standard you wish to use for the threading.

 

 

Available Options:

 

 

This option allows to create the threading along the entire length of the selected face.

 

 

This option specifies the length of tapping (measured in relation to the original plane).

If the Complete tapping is set to True, the length is grayed.

 

 

This option allows to create the actual thread shape for 3D printing.

 

Here's how to make a user threading standard compatible with 3D modeling:

  • In a 2D model document, draw internal and external thread profiles (in 2 different sketches).

  • Provide the Threading profile function to this 2D model document and fill publications (profiles, positioning frames, diameters ...).

  • Into your threading standard document, select your 2D model document in the Thread profile field.

For example, you can copy/paste and customize the 2D model document Metric ISO 724 available in the TopSolid library, Threads folder.

 

3D modeling is not compatible with tapered threads.

 

 

 

  • Standard: This option allows you to select the threading standard to use from those found in the project or references.

The threading dimension is automatically selected from the dimensions available in the standard based on the diameter of the cylindrical face selected.

If this option is deactivated, you have to fill every tapping values (Description, nominal diameter, pitch, internal diameter, but also in the advanced tab, if the tapping is left hand or not).

  • Strict: If this option is checked, the diameter of the selected cylinder must be strictly the same than the diameter of the selected standard.

 

 

  • Thread start number: Allows to define the tread start number. This value is generally set to 1.

  • Left hand: Allows to define the thread direction. This value is generally set to False.
