SolidWorks Advance Thread Wizard

An add-in for SolidWorks that models threads from the standards, including tapered pipe threads, using the thread data of this site. It is not released yet; the video shows a trial version.

SolidWorks 2020 and later Release date to be announced
A preview of the unreleased trial version.

What it does

  • True 3D tapered threads

    Cuts real helical threads on tapered surfaces such as NPT pipe fittings, not a cosmetic line.

  • Specifications inside SolidWorks

    Loads the ASME reference specification for the chosen thread in the PropertyManager, so you do not leave the model to look up sizes.

  • Native thread profiles

    Works with SolidWorks thread profile files (.SLDLFP), the same format as the Thread Library on this site.

  • Wrench-tight sealing check

    Simulates the metal-to-metal interference of a tapered joint tightened with a wrench.

Series it will cover

The trial has data for the Unified (UN) and NPT threads. The other series are in progress or planned: they are the ones this site has pages for. The final list is announced at release.
