Create lines and triangles/polygons

<p>Hi,</p><p>how can I create lines or triangles/polygons? In version 2014 I ofter used the create lines feature together with the Extrude-feature to rebuild geometries with a hugh amount of triangles/polygons. In my point of view it is an important feature for component modeling. In general a real sketch-function to create features would be a real improvement.</p><p> </p><p>br/Ralle</p>
