Arch MultiMaterial/es

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 with a MultiMaterial will use the material definitions and thicknesses to create a multi-layer wall
 * Windows 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 with a MultiMaterial will use the material definitions and thicknesses to create a multi-layer panel

How to use

 * 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  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.
