Arch

Popis

If no profile is given, a set of presets are available to quickly build a structural element from a predefined standard profile.

Použití

Vlastnosti

An Arch Structure object shares the common properties and behaviors of all Arch Components.

Data

View

• PohledNodes Type: The type of structural nodes of this object, linear or area.
• PohledShow Nodes: Shows or hides the structural nodes.

Presets

The Structure tool also features a series of presets that allow to quickly build standard metallic profiles or precast concrete elements.

Some presets for steel structures

The presets are obtained by choosing a Category from the structure options panel. Available categories are Precast concrete or any of the industry-standard metallic profiles such as HEA, HEB or INP. For each of these categories, a number of presets are available. Once a preset is chosen, its individual parameters such as Length, Width or Height can be adjusted. However, for metallic profiles, the profile size is set by the preset and cannot be changed.

The Switch L/H button can be used to switch Length and Height values, and therefore building a horizontal beam rather than a vertical column.

Structural nodes

Structural objects also have the ability to display structural nodes. Structural nodes are a sequence of 3D points stored in a "Nodes" property. By switching the "Show Nodes" view property on/off, one can see the structural nodes of a structural element:

Structural nodes made visible for a set of structures

• Nodes are calculated and updated automatically, as long as you don't modify them manually. If you did, they won't be updated if the shape of the structural object changes, unless you use the "Reset nodes" tool below.
• Arch structures can have not only linear nodes, but also planar nodes. For this, 1- There must be at least 3 vectors in the "Nodes" property of the object, 2- the "NodesType" property of their ViewObject must be set to "Area".
• When the nodes calculation is automatic (that is, if you never touched them manually), when setting the "Role" property of a structure to "Slab", it will automatically become a planar node (there will be more than 3 vectors and the NodesType will be set to "Area").
• When editing a structure object (double-click), a couple of node tools are available in the task view:
  • Reset the nodes to automatic calculation, in case you modified them manually
  • Edit the nodes graphically, works the same way as Draft Edit
  • Extend the nodes of the edited object until it touches the node of another object
  • Make the node of this object and another one coincident
  • Toggle the display of all nodes of all structural objects of the document on/off

Scripting

structure = makeStructure(baseobj=None, height=None)
structure = makeStructure(baseobj=None, length=None, width=None, height=None, name="Structure")

Příklad:

import FreeCAD, Draft, Arch

rect = Draft.make_rectangle(200, 300)
structure1 = Arch.makeStructure(rect, height=2000)
FreeCAD.ActiveDocument.recompute()

structure2 = Arch.makeStructure(None, length=500, width=1000, height=3000)
Draft.move(structure2, FreeCAD.Vector(2000, 0, 0))
FreeCAD.ActiveDocument.recompute()
