Draft BSpline/ru

Описание
Инструмент BSpline создает кривую B-Spline из нескольких точек текущей work plane. Он берет linewidth and color, предварительно установленный на вкладке «Задачи». Инструмент BSpline ведет себя точно так же, как инструмент Draft Wire.



How to use

 * 1) Press the  button, or press  then  keys
 * 2) Click a first point on the 3D view, or type a coordinate
 * 3) Click additional point on the 3D view, or type a coordinate
 * 4) Press  or, or double-click the last point, or click on the first point to finish or close the spline. If the spline is closed, it will also be a face, even if it appears as wireframe.

Options

 * Press or the  button to finish the spline, leaving it open
 * Press or the  button or click on the first point to finish the spline, but making it closed by adding a last segment between the last point and the first one.
 * 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.
 * Press or click the checkbox to check/uncheck the  button. 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 (0,0,0) origin point.
 * Press or click the checkbox to check/uncheck the  button. If continue mode is on, the BSpline tool will restart after you finish or close it, allowing you to draw another one without pressing the BSpline button again.
 * Press while drawing to force snapping your point to the nearest snap location, independently of the distance.
 * Press while drawing to constrain your next point horizontally or vertically in relation to the last one.
 * Press or press the  button to remove the existing segments and start the spline from the last point.
 * Press + or press the button to undo the last point.
 * Press or the  button to have the spline filled with a face after it has been closed.
 * Press or the  button to abort the current BSpline command.
 * BSplines, when in "Flat Lines" display mode, can display a hatch pattern, by setting their "Pattern" property below.

Properties

 * : Specifies if the spline is closed or not
 * : Fills the spline with a face
 * : Shows an arrow symbol at the last point of the spline, so it can be used as an annotation leader line
 * : Specifies a hatch pattern to fill the wire with
 * : Specifies the size of the hatch pattern

Scripting
The BSpline tool can by used in macros and from the python console by using the following function:


 * Creates a B-Spline object from the given list of vectors.
 * If closed is True or first and last points are identical, the wire is closed.
 * If face is true (and the bspline is closed), the bspline will appear filled.
 * Instead of a list of points, you can also pass a Part Wire.
 * Returns the newly created object.
