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!

Arch MultiMaterial

Description

The Multi-Material tool defines a list of materials with, for each material, a name and a thickness value. This multi-materials list can then be added to an Arch object instead of a single Arch Material .

Not all Arch objects can currently make use of multi-materials, and the use they do of it differs. Currently:

  • [Walls](wiki-test2.php?gitpage=Arch_Wall) with a MultiMaterial will use the material definitions and thicknesses to create a multi-layer wall
  • [Windows](wiki-test2.php?gitpage=Arch_Window) with a MultiMaterial will attribute materials with a given name defined inside the MultiMaterial to window components with a same name or type (see below). Material thickness is not considered.
  • [Panels](wiki-test2.php?gitpage=Arch_Panel) with a MultiMaterial will use the material definitions and thicknesses to create a multi-layer panel

Usage

  1. Create first a series of Arch Materials that you will need in your Multi-Material.
  2. Optionally, select an Arch object you wish to attribute the new Multi-Material to.
  3. Press the Multi-Material button.
  4. Set the desired material layers.

Options

Upon creating or editing a multi-material by double-clicking it in the tree, the following options are available:

  • Duplicate another existing Multi-Material from the same document. This only copies the values over, and doesn\'t link the two multi-materials in any way.
  • The Name field will also set the material object\'s Label
  • The Composition list is the list of the different material layers that compose this multi-material. Each layer has a name, a material and a thickness value.
  • Click Add to add a new layer, Up to move a selected layer up, Down to move a selected layer down, or Del to delete a selected layer.
  • Double-click the name of a layer to edit it, the material will offer you a drop-down list of available Arch Materials in the same document, and thickness can be set to any value in any unit
  • Name and Material fields are mandatory. Thickness can be left blank (it will then adopt a value of 0).
  • When a multi-material contains layers with a thickness of zero, that thickness is considered variable. Arch objects that use the multi-material, such as Walls and Panels, will treat that accordingly, and give that layer the remaining space available given their own width or thickness.
  • If you name the different components of a multi-material \"Frame\", \"Solid panel\", \"Glass panel\" or \"Louvre\", and apply that material to a window, the given materials will be applied to the corresponding window components.

Relation to IFC

This roughly corresponds to a combination of IfcMaterialLayerSet and IfcMaterialLayer.
