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.

We call sponsoring the act of donating money recurrently to the FreeCAD project. You can do that as an individual or as a company or institution, through different channels or platforms, depending on your preferences.

Sponsoring FreeCAD allows its developers to count on a steady flow of income, so it allows the FPA to plan things ahead, and the FreeCAD developers to invest themselves more seriously into FreeCAD.

To encourage persons and companies to sponsor the FreeCAD project, we have created different sponsoring tiers. When donating regularly to the project, unless you prefer to stay anonymous, your name, company name and/or logo will be featured on this website, depending on the tier you fit into:

  • ♥ Normal sponsor : 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.
  • 🥉 Bronze sponsor : from 25 USD / 25 EUR per month. Your name or company name is displayed on this page.
  • 🥈 Silver sponsor : 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.
  • 🥇 Gold sponsor : 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!

BCF support

This project was realized during GSOC 2019

This page is dedicated to the description of the Google Summer of Code 2019 project idea of adding BCF support to FreeCAD.

Outline

BIM Collaboration Format (or BCF) is a file format aimed at coordinating the work of several participants in a Building Information Modeling (BIM) project. The format specifications are maintained by BuildingSMART, the same consortium behind the IFC file format.

The BCF format implements a series of tools to allow users to create, annotate, classify, comment, discuss and solve issues on a BIM model. It works as a thin layer containing issues related to a BIM model. The BCF file itself doesn\'t contain or relate explicitly to the model, which allow different people who work on a same project but with different applications to still be able to discuss and process the same issues.

This project idea proposes to implement a BCF viewer for FreeCAD. The viewer would allow to:

  • Open BCF files
  • View the different issues with their comments and images (screenshots)
  • Navigate in a FreeCAD model to a camera position stored in the BCF file
  • Comment, annotate, classify and tag issues
  • Create new issues, save screenshots and camera position
  • Save BCF files
  • If time permits, explore the possibilities of server-based BCF serving (API)

Details

  • Get familiar with FreeCAD and the current state of BIM tools
  • Get familiar with PySide and Qt
  • Get familiar with the BCF format, gather a series of test files
  • Implement the different functions needed to interact with BCF files and data
  • Implement a Graphical User Interface to these functions

Expected Outcome

  • Documentation. Like all open-source projects, it is of uttermost importance to document a lot everything you do. This allows for other people to take on and extend your work more easily.
  • A complete, working GUI application, that works as a plugin/addon inside FreeCAD.

Future Possibilities

BCF use in the BIM industry is still at its infancy. One can think of many possible extensions, such as:

  • Connecting with other (open-source) communication structures: forums, chat/messaging systems, etc...
  • Connecting with other issues tracking systems

Project Properties

Skills

  • Programming language: Python + PySide
  • Knowledge of BIM modeling and workflows is a plus, or be ready to practice!

Difficulty

Medium

Additional Information

  • Potential mentors: Yorik
