Donation Sponsor

$5 $10 $25 $100 $200 Other

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!

Assembly3 ConstraintAxial

Description

This tool builds a link between two or more objects of an assembly and matches their orientation. The selected elements of each object or more precisely their implicit coordinate systems (ICS) are used to position one object to another.

Assuming the first object is already locked in place by the Lock constraint then the following objects are moved to positions where the z-axes are collinear .

The offset of their origins on their common z-axis and the angle between their x-axes (and y-axes as well) are not defined. Related to the first object the following objects can still move along and spin around the z-axis. This is leaving 2 degrees of freedom (DOFs) for each link unconstrained.

The constraint accepts

: - straight edges, which become collinear, : - planar faces, which are aligned using their surface normal axis, : - cylindrical faces, which are aligned using the axial direction.

Different types of geometry elements can be mixed.

Usage

Place two or more objects into an assembly.
Select one element of each object.
Activate the Assembly3 ConstraintAxial command using:
- The Create "AxialAlignment" constraint button.

Kinematic Equivalent

Used in kinematic context this constraint resembles a cylindrical joint.

In real life we cannot handle axes and so cylindrical faces are used to represent the linked axes.

Constrained objects before and after running the solver and then slid along the axis
