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!

Description

The SheetMetal AddJunction command creates open junctions between two sections (walls/flanges) of a sheet metal object. Without these junctions sheet metal sections connected to the same base will not be unfoldable.

This command is the second of three steps to convert a shell object made with the Part Workbench or PartDesign Workbench into an unfoldable sheet metal object:

  1. SheetMetal AddRelief
  2. SheetMetal AddJunction
  3. SheetMetal AddBend

Make Junction - cut edges open

Usage

  1. Select one or more edges.
  2. There are several ways to invoke the command:
    • Press the Make Junction button.
    • Select the SheetMetal → Make Junction option from the menu.
    • Right-click in the Tree view or the 3D view and select the SheetMetal → Make Junction option from the context menu.
    • Use the keyboard shortcut: S then J.
  3. The Junction properties Task panel opens (introduced in version 0.5.00).
  4. Optionally press the Select button to add more faces.
    • Press the Preview button to finish the selection and display the changes.
  5. Optionally adjust the parameters in the Task panel.
  6. Press the OK button to finish the command and close the Task panel.
  7. A Junction object will be created consisting of one opening at each selected edge.
  8. Optionally adjust the parameters in the Property editor.

Notes

  • The commands SheetMetal AddRelief, SheetMetal AddJunction, and SheetMetal AddBend work best with hollow cuboids i.e. shell objects with a constant thickness and only 90° angles between faces.
  • See SheetMetal AddRelief for hints about creating shell objects of cuboids.
  • Junction in this case is not the result of this tool, which is a gap between adjacent planar faces, but rather describes the location where two planar faces of the finished real world object meet, to be welded, for example.

Properties

See also: Property editor.

A SheetMetal Junction object is derived from a Part Feature object or, if it is inside a PartDesign Body, from a PartDesign Feature object, and inherits all its properties. It also has the following additional properties:

Data

Parameters

  • Database Object (LinkSub): "Base Object". Links to the edges defining gap/junction positions.
  • Datagap (Length): "Junction Gap". Default: 2,00 mm.Size of gap/junction to be added.
