Draft Wire/zh-cn

描绘
利用连线工具可创建一条折线(一系列互连的线段). 本工具利用底图工具栏中的底图线条样式进行绘制. 除了允许用户输入2个以上的点之外，连线工具与底图线段工具的行为完全相同.

B样条工具与连线工具的功能相似，区别仅在于前者中的每条线段为曲线而非直线. 利用Use Draft WireToBSpline工具可令两者互相转换.



如何使用

 * 1) 按下按钮，或先按键再按键.
 * 2) 在3D视图中点击第一个点，或输入一个坐标再按按钮.
 * 3) 在3D视图中单击另一个点，或输入一个坐标再按按钮.
 * 4) 按键或按钮来结束本次编辑.

双击树状视图中的元素或点击按钮即可编辑连线. 接下来，您可以将其中的点移到一个新位置，或点击或按钮再点选连线来增添其中的点.

融合多条线段
如果选中了若干条相连的线段，并按下按钮，便会将它们转换为一条连线并退出当前的命令.

不同线段的首尾准确重合才能进行融合，反之则不可. 必要时，可以手动调整线段首尾端点的坐标，或利用Draft Snap搭配Draft Endpoint模式来令端点重合.

Options

 * Press or the  button to finish the wire, leaving it open.
 * Press or the  button to close the wire, that is, a segment will be added from the last point to the first one to form a face. At least three points are required to form a face.
 * Press or the  button to remove the line segments already placed, but keep editing the wire from the last point.
 * Press or the  button to adjust the current working plane in the orientation of the last point.
 * Press, or  after a point to constrain the next point on the given axis.
 * To enter coordinates manually, simply enter the numbers, then press between each X, Y and Z component. You can press the  button when you have the desired values to insert the point.
 * Press or click the checkbox to toggle relative mode. If relative mode is on, the coordinates of the next point are relative to the last one; if not, they are absolute, taken from the origin (0,0,0).
 * Press or click the checkbox to toggle continue mode. If continue mode is on, the Wire tool will restart after you finish the wire, allowing you to draw another one without pressing the tool button again.
 * Press or click the checkbox to toggle filled mode. If filled mode is on, a closed wire will create a filled face ; if not, the closed wire will not make a face.
 * the wire should not be filled if it intersects itself, as it won't create a proper face. If the wire is filled but no shape is visible, manually set to  to see the wire.


 * Hold while drawing to force snapping your point to the nearest snap location, independently of the distance.
 * Hold while drawing to constrain your next point horizontally or vertically in relation to the last one.
 * Press + or press the button to undo the last point.
 * Press or the  button to abort the current command; line segments already placed will remain.

属性
连线对象享有Draft Line中的所有属性，但是大多属性仅对连线而言才有意义.

Data

 * : specifies the first point in the wire.
 * : specifies the last point in the wire, not counting the initial point if the wire is closed.
 * : specifies if the wire is closed or not. If the wire is initially open, this value is ; setting it to will draw a line segment to close the wire. If the wire is initially closed, this value is ; setting it to  will remove the last line segment, and make the wire open.
 * : specifies the size of the chamfers (straight segments) created on the corners of the wire.
 * : specifies the radius of the fillets (arc segments) created on the corners of the wire.
 * : specifies if the wire makes a face or not. If it is a face is created, otherwise only the edges are considered part of the object. This property only works if  is.
 * do not set to  if the wire intersects itself, as it won't create a proper face.


 * : specifies the number of interior nodes in each segment of the wire.
 * : (read-only) specifies the length of the entire wire.

View

 * : if it is it will display a symbol at the last point of the wire, so it can be used as an annotation line.
 * : specifies the size of the symbol displayed at the end of the wire.
 * : specifies the type of symbol displayed at the end of the wire, which can be "Dot", "Circle", "Arrow", or "Tick".
 * : specifies a Draft Pattern with which to fill the face of the closed wire. This property only works if is, and if  is "Flat Lines".
 * : specifies the size of the Draft Pattern.

脚本
Draft API与FreeCAD Scripting Basics.

借助下列函数即可在宏与Python控制台中使用连线绘制工具：


 * Creates a object with the given list of points,.
 * Each point in the list is defined by its, with units in millimeters.
 * Alternatively, the input can be a, from which points are extracted.
 * If is, or if the first and last points are identical, the wire is closed.
 * If a is given, it is used; otherwise the shape is created at the origin.
 * If is, and the wire is closed, the wire will make a face, that is, it will appear filled.
