Arch Wall/it

Descrizione
Questo strumento crea un oggetto Muro utilizzando come base una forma o oggetto mesh. Un muro può essere costruito anche senza alcun oggetto di base, nel qual caso si comporta come un volume cubico, utilizzando le proprietà lunghezza, larghezza e altezza. Quando è costruito usando una forma esistente, un muro può essere basato su:


 * Un oggetto lineare 2D, come ad esempio una linea, un arco, una spezzata o uno schizzo, in questo caso è possibile modificarne lo spessore, l'allineamento (a destra, a sinistra o al centro) e l'altezza.
 * Una faccia o una superficie piana, nel qual caso si può modificare solo l'altezza. Le proprietà Lunghezza e larghezza non hanno alcun effetto. Se la faccia di base è verticale, invece, il muro utilizza la proprietà larghezza invece di altezza, e consente di costruire pareti usando lo spazio come oggetto o studi della massa.
 * Un solido, nel qual caso non è possibile cambiare nulla. La parete utilizza semplicemente il solido base come sua forma.
 * Un mesh, nel qual caso il mesh deve essere un solido non-manifold chiuso.

L'esempio sopra mostra delle pareti costruite su una linea, su una spezzata, su una faccia, su un solido e su uno schizzo.

Walls can also have additions or subtractions. Additions are other objects whose shapes are joined in this Wall's shape, while subtractions are subtracted. Additions and subtractions can be added with the Arch Add and Arch Remove tools. Additions and subtractions have no influence over wall parameters such as height and width, which can still be changed. Walls can also have their height automatic, if they are included into a higher-level object such as floors. The height must be kept at 0, then the wall will adopt the height specified in the parent object.

When several walls should intersect, you need to place them into a floor to have their geometry intersected.

Drawing a wall from scratch

 * 1) Press the Arch Wall button, or press  then  keys
 * 2) Click a first point on the 3D view, or type a coordinate
 * 3) Click a second point on the 3D view, or type a coordinate

Drawing a wall on top of a selected object

 * 1) Select one or more base geometry objects (Draft object, sketch, etc)
 * 2) Press the Arch Wall button, or press the  then  keys
 * 3) Adjust needed properties such as height or width.

Options

 * The height, width and alignment of a wall can be set during drawing, via the task panel
 * When snapping a wall to an existing wall, both walls will be joined into one. The way the two walls are joined depends on their properties: If they have the same width, height and alignment, and if the option "join base sketches" is enabled in the Arch preferences, the resulting wall will be one object based on a sketch made of several segments. Otherwise, the latter wall will be added to the first one as addition.
 * Press, or  after the first point to constrain the second point on the given axis.
 * To enter coordinates manually, simply enter the numbers, then press between each X, Y and Z component.
 * Press or click the checkbox to check/uncheck the Relative button. If relative mode is on, the coordinates of the second point are relative to the first one. If not, they are absolute, taken from the (0,0,0) origin point.
 * Press while drawing to constrain your second point horizontally or vertically in relation to the first one.
 * Press or the Cancel button to abort the current command.
 * Double-clicking on the wall in the tree view after it is created allows you to enter edit mode and access and modify its additions and subtractions

Snapping
Snapping works a bit differently with Arch walls than other Arch and Draft objects. If a wall has a baseline object, snapping will anchor to the base object, instead of the wall geometry, allowing to easily align walls by their baseline. If, however, you specifically want to snap to the wall geometry, pressing will switch snapping to the wall object.

Properties
Wall objects inherit the properties of Part objects, and also have the following extra properties:
 * : The alignment of the wall on its baseline: Left, right or center
 * : The base object this wall is built on
 * : The index of the face from the base object to use. If the vaue is not set or 0, the whole object is used
 * : If True, and the wall is based on a face, only the border wire of the face is used, resulting in a wall bordering the face
 * : The length of the wall (not used when the wall is based on an object)
 * : The width of the wall (not used when the wall is based on a face)
 * : The height of the wall (not used when the wall is based on a solid)
 * : An extrusion direction for the wall. If set to (0,0,0), the extrusion direction is automatic.

Scripting
The Wall tool can by used in macros and from the python console by using the following function:
 * Creates a wall based on the given object, which can be a sketch, a draft object, a face or a solid. align can be "Center","Left" or "Right". If you provide no base object, then you can use numeric values for length, width and height. Face can be used to give the index of a face from the underlying object, to build this wall on, instead of using the whole object.
 * Returns the created wall, or None if the operation failed.
