Description
The corners of a Draft Wire can be filleted (rounded) or chamfered by changing its 数据Fillet Radius or 数据Chamfer Size respectively. It is also possible to subdivide the edges of a Draft Wire by changing its 数据Subdivisions property.

如何使用
- 按下
Draft Wire按钮,或先按W键再按I键。
- 在3D视图中点击第一个点,或输入一个坐标再按
add point按钮。
- 在3D视图中单击另一个点,或输入一个坐标再按
add point按钮。
- 按Esc键或Close按钮来结束本次编辑。
Options
The single character keyboard shortcuts available in the task panel can be changed. See Draft Preferences. The shortcuts mentioned here are the default shortcuts.
选项
- 按A键或
Finish按钮来结束当前连线的绘制,并关闭对此连线的编辑。 - 按O键或
Close按钮令当前连线闭合,即一条线段将连接当前连线首尾两点,从而构成一个面。而构成一个面则最少需要三个点。 - 按W键或
Wipe按钮来移除刚画好的线段,但是将继续保持从前一个点的位置继续编辑连线。
- 按U键或
Set WP按钮根据前一个点的方位来调整当前的工作平面。
- 在创建一个点后,按X、Y或 Z键来在对应轴上约束下一个点。
- 为了手动输入坐标,每当设置好X、Y、Z分量后都要按下Enter键。当您需要以特定坐标值插入一个点时,可点击
按钮。
- 按R键或点击relative多选框切换至相对 模式。若开启了相对模式,则后一个相对于前一个的坐标而定;否则采用绝对坐标,即相对原点(0,0,0)定后一个点的坐标。
- 按T键或点击continue多选框切换至连续(绘制)模式。若开启了连续模式,则连线工具在绘制一条连线后会自动重启,即允许您在不用点击连线工具的情况下,继续绘制下一条连线。
- 按L键或点击filled多选框切换至填充模式。若开启了填充模式,则一条闭合的连线将创建出一个填充面(数据Make Face
true); 否则,闭合的连线将不会创建出一个面(数据Make Facefalse)。
- 请注意: 若连线存在自相交的情况,便不能对其进行填充存在,因为它将无法创建对应真面(proper face)。如果对连线填充后却无法看到它本身的形状,就手动将数据Make Face设置为
false来查看连线。
Join
Usage
- The end points of the Draft Lines and/or Draft Wires to be joined must be exactly coincident. If required first adjust points to ensure that this is the case.
- Select two or more Draft Lines and/or Draft Wires.
- There are several ways to invoke the command:
- Press the
Draft Wire button.
- Select the Drafting →
Polyline option from the menu.
- Use the keyboard shortcut: P then L.
- Press the
Notes
双击树状视图中的元素或点击 Draft Edit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
add point或
remove point按钮再点选连线来增添其中的点。
Properties
See also: Property View.
A Draft Wire object is derived from a Part Part2DObject1.0 and below or a Part Feature object1.1 and above and inherits all its properties. It also has the following additional properties:
Data
Attachment
The object has the same attachment properties as a Part Part2DObject.
Draft
数据
- 数据Start: 指定连线中的第一个点。
- 数据End: 指定连线中的最后一个点,如果是闭合连线则不计入初始点。
- 数据Closed: 指定连线是否闭合。如果连线原本是开放的,此值为
false;将其设置为true则为会原连线再绘制一条线段使之闭合。如果连线原本就是闭合的,此值为true;将其设置为false则会从连线中去掉最后一条线段,令其变为开放连线。 - 数据Chamfer Size: specifies the size of the chamfers (straight segments) created on the corners of the wire.
- 数据Fillet Radius: specifies the radius of the fillets (arc segments) created on the corners of the wire.
- 数据Make Face: 指定是否令连线构成一个面。如果为
true则创建一个面,否则仅绘制本对象中的边。如果数据Closed为true时,本属性才会生效。
- 请注意:如果连线自相交,则不要将数据Make Face设置为
true,因为在这种情况下不能用它来创建一个真面(proper face)。
- 数据Subdivisions: 指定连线中每条线段内的内部节点数量。introduced in 0.16
- 数据Length: 指定整条连线的长度(只读属性)。

视图
脚本
wire = make_wire(pointslist, closed=False, placement=None, face=None, support=None)
wire = make_wire(Part.Wire, closed=False, placement=None, face=None, support=None)
- 利用指定的一个点列表
pointslist来创建一个Wire对象。- 列表中的每个点都被定义为
FreeCAD.Vector,单位为毫米。 - 或者, 输入也可以是一个
Part.Wire,从中提取各点。
- 列表中的每个点都被定义为
- 如果
closed为True,或者如果连线中的第一个点与最后一个点为同一点,则连线是闭合的。 - 如果指定了
placement,则在此位置创建连线;否则在原点处创建连线。 - 如果
face为True,且连线是闭合的,则连线将构成一个面,即表现为一个填充图形。
示例:
import FreeCAD as App
import Draft
doc = App.newDocument()
p1 = App.Vector(0, 0, 0)
p2 = App.Vector(1000, 1000, 0)
p3 = App.Vector(2000, 0, 0)
wire1 = Draft.make_wire([p1, p2, p3], closed=True)
wire2 = Draft.make_wire([p1, 2*p3, 1.3*p2], closed=True)
wire3 = Draft.make_wire([1.3*p3, p1, -1.7*p2], closed=True)
