While Stripe doesn't support monthly donations, you can still become a sponsor! Simply make a one-time donation equivalent to 12 months of support, and you'll gain access to the corresponding sponsoring tier. It's an easy and flexible way to contribute.

If you are not sure or not able to commit to a regular donation, but still want to help the project, you can do a one-time donation, of any amount.

Choose freely the amount you wish to donate one time only.

You can support FreeCAD by sponsoring it as an individual or organization through various platforms. Sponsorship provides a steady income for developers, allowing the FPA to plan ahead and enabling greater investment in FreeCAD. To encourage sponsorship, we offer different tiers, and unless you choose to remain anonymous, your name or company logo will be featured on our website accordingly.

from 1 USD / 1 EUR per month. You will not have your name displayed here, but you will have helped the project a lot anyway. Together, normal sponsors maintain the project on its feet as much as the bigger sponsors.

from 25 USD / 25 EUR per month. Your name or company name is displayed on this page.

from 100 USD / 100 EUR per month. Your name or company name is displayed on this page, with a link to your website, and a one-line description text.

from 200 USD / 200 EUR per month. Your name or company name and logo displayed on this page, with a link to your website and a custom description text. Companies that have helped FreeCAD early on also appear under Gold sponsors.

Instead of donating each month, you might find it more comfortable to make a one-time donation that, when divided by twelve, would give you right to enter a sponsoring tier. Don't hesitate to do so!

Choose freely the amount you wish to donate each month.

Please inform your forum name or twitter handle as a notein your transfer, or reach to us, so we can give you proper credits!

Description

A rail button is a small button attached to the side of the rocket that allows the rocket to be guided using a rail until it is fast enough to be aerodynamically stable.

Usage

  1. There are several ways to invoke the command:
    • Press the Rail Button button.
    • Select the Rocket → Launch Guides→ Rail Button option from the menu.
    • Double click on a Rail Button object in the Tree view.
  2. Set options and press OK.

Options

Rail Button Shapes

Rail buttons have two general shapes:

  • Round.

Round Rail Button

The round shape is the most common and is the simplest to manufacture in bulk. As the name implies, the button is round, with a groove that allows it to fit onto the launch rail. It may be glued to the main body, but is more typically fastened with a screw.

  • Airfoil.

Airfoiled Rail Button

The airfoil shape improved on the basic round button by giving it a more streamlined shape. Similar to the round button, it has a groove that allows it to fit on the launch rail. Adding a fillet on the top edges has been shown to further improve aerodynamic performance.
