This really looks pretty amazing. It seems like Onshape should be in a position to power some very advanced gear design software. I know from working with several different plastic injection molded gear designers that there are a lot of subtleties to tooth design for those types of systems (designing for shrink in plastic and the deflection characteristics). With the power of FeatureScript, I could see some of these types of esoteric custom software moving to Onshape.

oh I realized what it is - you need to make a version in order for other people to be able to reference the tool in other documents

Set Property (New Custom Feature!)

Set Property allows you to:

• Dynamically set the properties of your part or multiple parts.
  
• Set custom properties.

We are releasing an exciting new Custom Feature!

Introducing HAVF Profiles, built in collaboration with Austin Holbrook and Greg Brown. This feature comes loaded with an extensive library of airfoil profiles, guaranteeing continuity at the leading edge and providing control over the core variables of the profile, such as chord length or angle of incidence.

We hope this feature will enhance your toolset when creating airfoils, not only with the preconfigured library of vectors but also with the tools to create custom libraries and vector profiles. Our user testing found greater surface quality and faster development times. We think the feature is robust, but let us know your thoughts in the comments.

You can find the custom feature here: https://cad.onshape.com/documents/33795c7f9b39612da14ee99a/v/5f0353863c39e4e7468cf450/e/7d0549e4402995ffee27b9c5

This project stemmed from a collaboration with RCTestFlight, as Daniel and Austin collaborate using Onshape. Find their propeller design competition here: https://youtu.be/oTpa0WVHspA

The feature will construct a profile using two Bezier splines, with guaranteed surface continuity at the leading edge. The custom feature comes with a library of profiles, but you can also create a custom profile using a vector approximation of the airfoils in this format:

Included in the custom feature is a segment of the Holbrook Aerospace Profile library; you can find an expanded library of airfoils on the Holbrook Aerospace website. [https://holbrookaerospace.com/product/album-2/]. If you wish to implement more vectors into your library, we have added the database Feature Studio tab, havfDatabaseExample.fs. As the airfoil profiles we included in the feature are proprietary the core library is hidden, you can add a second database or switch to your own set of vector profiles.

We are eager to see what you build with the new tool. Please add your comments so we can consider any future enhancements.

This is not an official Onshape feature, and maintenance is not guaranteed.

I've asked about a means to create a freewheel functionality using the built-in mates earlier. It wasn't thought to be possible. I didn't find any useful workaround either, and I am not a FS wizard. Now I seem to have another project coming that calls for a function where things can rotate, but only one way. What do the FS experts think: Would it be possible to create a mate that is like the rotate mate in everything, but only allows rotation in one direction? That is: The angle of rotation may only count up or may only count down, depending on the configuration chosen?

Until there is FeatureScript in assemblies, I can’t see FS being a solution to this. I would put in an improvement request for a check box for revolute mates.
