Draft BezCurve/ro

Descriere
Instrumentul BezCurve creează o Bezier Curve (sau o curbă Bezier în bucăți) din mai multe puncte din planul curent work plane. Este nevoie de linewidth and color setată anterior pe fila Activități.

Obiectul este creat ca o singură curbă Bezier de grad (număr_de_ puncte - 1). Aceasta poate fi modificată la o curbă Bezier în parte, de un anumit grad după crearea folosind editor proprietăți. Bezier Curves poate fi editat folosind.

The Draft BezCurve and the Draft CubicBezCurve commands use to define the position and curvature of the spline. The Draft BSpline command, on the other hand, specifies the through which the curve will pass.





Cum se folosește
See also: Draft Tray, Draft Snap and Draft Constrain.


 * 1) There are several ways to invoke the command:
 * 2) * Press the button.
 * 3) * Select the option from the menu.
 * 4) * Use the keyboard shortcut: then.
 * 5) The  task panel opens. See Options for more information.
 * 6) Pick the first point in the 3D view, or type coordinates and press the  button.
 * 7) Pick additional points in the 3D view, or type coordinates and press the  button.
 * 8) Press  or the  button to finish the command.

Cum se foloseşte

 * 1) Apăsați butonul ,  sau apăsați  apoi tastele
 * 2) Faceți clic pe un prim punct din vizualizarea 3D sau tastați un  coordinate
 * 3) Faceți clic pe un punct suplimentar în vizualizarea 3D sau tastați un  coordinate
 * 4) Apăsați  sau  sau faceți dublu clic pe ultimul punct sau faceți clic pe primul punct pentru a termina sau a închide filamentul/polilinia. Dacă filamentul este închis, acesta va fi, de asemenea, o fațetă, chiar dacă acesta apare ca o rețea wireframe.

The single character keyboard shortcuts available in the task panel can be changed. See Draft Preferences. The shortcuts mentioned here are the default shortcuts.


 * Apăsați tasta sau butonul  pentru a finaliza funcția B spline, lăsând-o deschisă
 * 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 BezCurve tool will restart after you finish or close it, allowing you to draw another one without pressing the BezCurve 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.
 * Apăsați tasta sau butonul  penru a abandona comanda BezCurve.

Limitări

 * Acest instrument nu este disponibil înainte de versiunea FreeCAD 0.14
 * Proprietatea puncte nu apare încă în lista de proprietăți.
 * OpenCascade nu suportă Bezier Curve cu grad> 25. Aceasta nu ar trebui să fie o problemă în practică.

Preferences
See also: Preferences Editor and Draft Preferences.


 * To change the number of decimals used for the input of coordinates:.
 * To change the initial value of filled mode: . Changing the filled mode in a task panel will override this preference for the current FreeCAD session.

Proprietăți
See also: Property editor.

A Draft BezCurve object is derived from a Part Part2DObject and inherits all its properties. It also has the following additional properties:

Data

 * : (read-only) specifies the area of the face of the curve. The value will be if  if  or the face cannot be created.
 * : specifies if the curve is closed or not. If the curve is initially open this value is, setting it to will draw a segment to close the curve. If the curve is initially closed this value is , setting it to  will remove the last segment and make the curve open.
 * : (read-only) specifies the continuity of the curve.
 * : specifies the degree of the curve.
 * : (read-only) specifies the total length of the curve.
 * : specifies if the curve makes a face or not. If it is a face is created, otherwise only the perimeter is considered part of the object. This property only works if  is  and if the curve does not self-intersect.
 * : specifies the control points of the curve in its local coordinate system.

View

 * : specifies the size of the symbol displayed at the end of the curve.
 * : specifies the type of symbol displayed at the end of the curve, which can be, , , or.
 * : specifies whether to show a symbol at the end of the curve, so it can be used as an annotation line.
 * : specifies the Draft Pattern with which to fill the face of the closed curve. This property only works if is  and if  is.
 * : specifies the size of the Draft Pattern.
