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!

Reinforcement BillOfMaterial

Description

The Reinforcement BillOfMaterial tool allows the user to create a bill of material of reinforcing bars.

This tool is part of the Reinforcement Workbench, an external workbench that can be installed with the Addon Manager.

*Bill Of Material of reinforcing bars*

Usage

1. Select Arch Rebar and Rebar2 objects you want to include in the Bill Of Material. Or select Arch Structure objects to include Arch Rebar objects hosted by those into Bill Of Material. If nothing is selected, then Bill Of Material will be generated for all Arch Rebar and Rebar2 objects present in the model.

2. Then select Rebar Bill Of Material from the rebar tools.

3. A dialog box will pop-out on the screen as shown below.

:

:

Dialog Box for the Arch Rebar BOM tool

4. Modify data to suit your requirements.

5. To edit Rebar Bill Of Material SVG configurations, click on Edit SVG Configurations. A dialog box will pop-out as shown below.

:

:

Dialog Box for the Arch Rebar BOM SVG configuration editing

6. Modify Rebar Bill Of Material SVG configurations and then click on OK to apply changes.

7. Click OK or Apply to generate Bill Of Material for rebars.

8. Click Cancel to exit the dialog box.
