    Hi,

    you can create Sketch feature (i.e. planar datum curve) and use it as reference in several following features.

    yes your answer is good but my idea is to use construction lines in other extrude for example as refference

    is a posibility for this?

    somebody have other ideas?

    You can't use construction lines outside of the sketch, they are for construction of the sketch only.

    If you add a datum point within sketcher, it creates a point you can use as a reference  (or an axis if it's a sketch within an extrude.
