<p>The BSpline tool creates a <a rel="nofollow" class="external text" href="http://en.wikipedia.org/wiki/B-spline">B-Spline curve</a> from several points in the current <a href="Draft_SelectPlane.html" title="Draft SelectPlane">work plane</a>. It takes the <a href="Draft_Linestyle.html" title="Draft Linestyle">linewidth and color</a> previously set on the Tasks tab. The BSpline tool behaves exactly like the <a href="Draft_Wire.html" title="Draft Wire">Draft Wire</a> tool.

|
<p>The BSpline tool can by used in <a href="Macros.html" title="Macros">macros</a> and from the python console by using the following function:
|
|
</p>
|
|
<pre>makeBSpline (pointslist,[closed],[placement]) </pre>
|
|
<ul><li> Creates a B-Spline object from the given list of vectors. </li>
|
|
<li> If closed is True or first and last points are identical, the wire is closed. </li>
|
|
<li> If face is true (and the bspline is closed), the bspline will appear filled. </li>
|
|
<li> Instead of a list of points, you can also pass a Part Wire. </li>
|
|
<li> Returns the newly created object.</li></ul>
|
|
<p>Example:
|
|
</p>
|
|
<pre>import FreeCAD,Draft
|
|
p1 = FreeCAD.Vector(0,0,0)
|
|
p2 = FreeCAD.Vector(1,1,0)
|
|
p3 = FreeCAD.Vector(2,0,0)
|
|
Draft.makeBSpline([p1,p2,p3],closed=True) </pre>
