Allow projected sketch geometry to be used directly for extruded/revolved/swept/lofted surface features

[tstoutYZ3MS]

The current Inventor methodology of first projecting the necessary part edges, then duplicating that work by covering those same projected edges with line/arc/spline entities in order to be capable of selecting them for extruded/revolved/swept/lofted surface features is tedious, monotonous, and completely unnecessary. Autodesk needs to remedy this eggregious oversight by simply allowing the engineer to select the projected sketch geometry and subsequently extrude, revolve, sweep, and/or loft surface geometry.

What is the situation where you are not able to select the projected geometry?  Any chance you could post some pictures of the type of situation you're having trouble with?  

I ask because, assuming it isn't set as construction geometry, you should be able to select the projected geometry for all of the features you list.  You would have to draw new geometry on top of it if you needed to trim (or otherwise modify) the edges.  But if the original geometry as it was projected is what you need, you shouldn't usually need to redraw it.

In this example, the loft is between Sketch2 and a work point.  Sketch2 contains nothing but the geometry projected from a previous extrusion (nothing is manually drawn in the sketch). 

Projected Geometry as Loft Section

Make sure the edges aren't set as "construction geometry", construction lines are always ignored when extruding,... whether they are projected or not.

select the projected edges and turn off "construction"

Furthermore, in the application options you can choose whether Inventor defaults projected lines as construction or normal lines.

Splined edges, not set to construction geometry either. Inventor will not allow me so select the projected splines for extrusion as surfaces no matter what I attempt.

It sounds like you have a geometry-specific problem of some sort.  It is not a general rule that you can't select projected geometry for these types of features, so there must be some particular reason it isn't working for your case.
