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!

App OriginGroupExtension

Introduction

An App Origin object, or formally an App::OriginGroupExtension, is a class supplying selectable elements that represent the three standard axes (X, Y, Z) and three standard planes (XY, XZ and YZ) to objects that are intended to arrange different types of geometry in space.

[Std Part](wiki-test2.php?gitpage=Std_Part) [(App Part)](wiki-test2.php?gitpage=App_Part) objects and

[PartDesign Body](wiki-test2.php?gitpage=PartDesign_Body) objects are created with Origin objects by default. If needed, Origin objects can be added to

[Assembly](wiki-test2.php?gitpage=Assembly3_CreateAssembly) objects of the

[Assembly3](wiki-test2.php?gitpage=Assembly3_Workbench) workbench, too.

The axes and planes are objects of type App::Line and App::Plane respectively. Each of these elements can be hidden and unhidden individually with the Space bar. This can be useful when selecting the correct reference for creating other objects e.g. Sketches.
