Arch Grid

Description
The Grid tool allows you to place a grid-like object in the document. This object is meant to serve as a base to build Arch objects that need a regular but complex frame, such as windows, curtain walls, column grids, railings, etc. The Grid object is editable like a spreadsheet, where you can add or remove columns and rows, define their size, and merge cells.

The Grid is a 2D object, and can therefore be used anywhere a 2D shape such as a Draft or Sketch is needed, but it can also behave as a Arch AxisSystem, and be used to propagate the placement of other Arch objects.



The image above shows a grid of columns, a railing system and a window, each based on a Grid object.

How to use

 * 1) Press the  button.
 * 2) Set the Width and Height of the grid in the properties.
 * 3) Enter edit mode by double-clicking the grid object in the tree view.
 * 4) Add rows and columns.
 * 5) Set the desired width and height of rows and columns by double-clicking the row or column headers.

Options

 * A column width or row height of 0 means its size will be adapted automatically to fit the total width/height of the grid.
 * Cells can be merged and unmerged by selecting them and clicking the appropriate button.
 * When used as the property of other Arch objects, the grid will drive the positioning of these objects. The  property defines how the other objects are placed on the grid: At vertices, edge midpoints or face centers.
 * By setting the or  properties to a non-zero value, the total number of rows/columns and their individual heights/widths is ignored. Instead, the maximum number of columns or rows of the given auto width/height get automatically created.

Properties

 * : The number of rows
 * : The number of columns
 * : The sizes for rows
 * : The sizes of columns
 * : The type of 3D points produced by this grid object
 * : The total width of this grid
 * : The total height of this grid
 * : Creates automatic column divisions (set to 0 to disable)
 * : Creates automatic row divisions (set to 0 to disable)
 * : When in edge midpoint mode, if this grid must reorient its children along edge normals or not
 * : The indices of faces to hide

The Grid tool can be used in macros and from the Python console by using the following function:


 * Creates a object.

Its, , , and attributes can be changed directly to define the appearance of the grid.
