Draft Line/ru

Описание
Инструмент «Линия» создает прямую линию, определяемую двумя точками. Он использует набор Draft Linestyle на панели инструментов «Тревожный лоток». Инструмент «Линия» ведет себя точно так же, как инструмент Draft Wire, за исключением того, что он останавливается после двух точек.



Usage

 * 1) Press the  button, or use the  →  from the top menu, or use the keyboard shortcut:  then  keys.
 * 2) Click a first point on the 3D view, or type a coordinate and press the  button.
 * 3) Click a second point on the 3D view, or type a coordinate and press the  button.

The line can be edited by double clicking on the element in the tree view, or by pressing the button. Then you can move the points to a new position.

Fusing single lines
If several connected Draft Lines are selected they can be fused into a wire by pressing the tool; however, this  Wire will not be editable. To create an editable wire, use three more times on the new shapes (wire, closed wire, face). You can also fuse the original lines with the tool.

Adding points
A wire can also be created from a single line by adding another point anywhere along its length. To do this, press the button, and click anywhere on the line.

Options

 * 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.
 * You can also define the polar coordinates of the point by giving a value to "Length" and "Angle". Click on the checkbox next to "Angle" to constrain the pointer to the specified angle.
 * 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 second point are relative to the first 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 Line tool will restart after you give the second point, allowing you to draw another line segment without pressing the tool button again.
 * Hold while drawing to force snapping your point to the nearest snap location, independently of the distance.
 * Hold while drawing to constrain your second point horizontally or vertically in relation to the first one.
 * Press + or press the button to undo the last point.
 * Press or the  button to abort the current command.

свойства

Data

 * : specifies the start point.
 * : specifies the end point.
 * : specifies the number of interior nodes in the line.
 * : (read-only) specifies the length of the segment.

View

 * : if it is it will display a symbol at the last point of the line, so it can be used as an annotation line.
 * : specifies the size of the symbol displayed at the end of the line.
 * : specifies the type of symbol displayed at the end of the line, which can be "Dot", "Circle", "Arrow", or "Tick".

Scripting
Draft API and FreeCAD Scripting Basics.

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


 * Creates a object between points  and, each defined by its , with units in millimeters.
 * Creates a object from a.
 * Creates a object from the first vertex to the last vertex of the given.
