How to model an inclined linear support/guiding ?

In some cases one wants to analyze a mechanism with an inclined linear guiding, which can not be modeled by "fixing" a node because this approach only works for horizontal or vertical linear guiding.

However, an inclined linear support can be modeled on the basis of the slider element. By fixing both the node and the angle of the base point of the slider, the moving node can only slide along a fixed line.
