<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Is it possible to use a node as the coordinate for \psStartPoint (Cartesian and polar coordinates work) as in the following example that does not work: vector D is not drawn.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">I would like to start a new vector sequence from the end of vector F’_1 (I don’t want to compute its Cartesian coordinates as I know its name is Vector2), I would like to use \psStartPoint(Vector2) or \psStartPoint[newnode-name](Vector2)
to simply continue the sequence of vectors. <o:p></o:p></span></p>
