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!

Swept-path Analysis GSoC Project

This page is describes a potential 2018 Google Summer of Code project regarding configuration management for the FreeCAD CAE application.

Outline

In Transportation Engineering, a common need is a \"swept-path analysis\", which simply analyzes the path a vehicle takes as it turns a corner. Vehicles of differing dimensions and wheel bases, obviously, have different turning capabilities, so it\'s necessary to ensure public facilities are designed to accommodate the least agile vehicles that are expected to use it.

Commercial packages exist which do this. The industry standard in the US is AutoTURN and sells for about \$12,000 per license. Despite the price, the technology and theory behind the software has been known and understood for well over 50 years. Yet, apart from one freeware (closed source) option, no freely available tools to perform this analysis exist.

Details

  1. Develop a simple database (a CSV file) which contains the key parameters for the design vehicles used in the analysis. This data includes parameters like vehicle height, length, width, axle count, wheel base, and others.
  2. Develop several generic vehicle templates as separate sketches into which the database parameters can be fed to create a template which represents a real-world vehicle.
  3. Create a Part-based geometry from the sketch object representing the design vehicle and generate a mesh
  4. Import a data file (DXF) which contains the roadway gemetry on which to run the analysis.
  5. Choose lines from the imported file which act as boundaries for the analysis collision detection.

Expected Outcome

  1. Accomplishing these items would provide the basis for performing swept path analyses in FreeCAD.

Future Possibilities

This work will provide exposure to highway design techniques.
