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!

Sketcher CreateArc

Description

The Sketcher CreateArc tool creates an arc by its center and its endpoints. (v1.0) : Or optionally by its endpoints and a point along the arc.

*Arc created in Center mode with automatically applied constraints defined by entering all On-View-Parameters*

Usage

See also: Drawing aids.

Pos-OVP = Positional On-View-Parameters. (v1.0) Dim-OVP = Dimensional On-View-Parameters. (v1.0)

  1. There are several ways to invoke the tool:
    • Press the Center and endpoints button.
    • Select the Sketcher → Sketcher geometries → Create arc by center option from the menu.
    • Right-click in the 3D view and select the Create arc by center option from the context menu.
    • Use the keyboard shortcut: G then A.
  2. The cursor changes to a cross with the current tool mode icon.
  3. The Arc parameters section ((v1.0) ) is added at the top of the Sketcher Dialog.
  4. Optionally press the M key or select from the dropdown list in the parameters section to change the tool mode:
    • **Center**: 1. Pick the center of the arc. Or with Pos-OVP: enter its X and/or Y coordinate. 2. Pick the start point of the arc, this also defines the radius. Or with Dim-OVP: enter the radius and/or start angle of the arc. The angle is relative to the X axis of the sketch. No constraint is created for this angle. 3. Pick the endpoint of the arc. Or with Dim-OVP: enter the aperture angle of the arc.
    • **3 rim points**: (v1.0) 1. Pick the start and end points of the arc. Or with Pos-OVP: enter their X and/or Y coordinates. 2. Pick another point to define the radius. Or with Pos-OVP: enter its X and/or Y coordinate. No constraints are created for this point.
  5. The arc is created and applicable Pos-OVP and Dim-OVP based constraints are added.
  6. If the tool runs in continue mode:
    1. Optionally keep creating arcs.
