Projected Curve, Terminology

famadorian

I'm wondering about a few things here: 

1. why does the box ask for "sketch"; isn't it an entity or a sketch entity it should ask for? You pick an entity here, not a full sketch, which might include several sketch entities
2. why can't a sketch entity be a construction entity? If I try to make "Edge of stigning" a construction spline, it fails.

It could be changed in the Projected curve feature

        annotation { "Name" : "First sketch", "Filter" : EntityType.EDGE && SketchObject.YES && ConstructionObject.NO }
        definition.sketchEdges1 is Query;
        annotation { "Name" : "Second sketch", "Filter" : EntityType.EDGE && SketchObject.YES && ConstructionObject.NO }
        definition.sketchEdges2 is Query;

could be:

        annotation { "Name" : "First sketch entity", "Filter" : EntityType.EDGE && SketchObject.YES }
        definition.sketchEdges1 is Query;
        annotation { "Name" : "Second sketch entity", "Filter" : EntityType.EDGE && SketchObject.YES }
        definition.sketchEdges2 is Query;

I would like the change proposed in 1) and I do not see any problem in making the change proposed in 2)

I have created an improvement request here https://forum.onshape.com/discussion/10883/change-projected-curve-precondition/p1?new=1

1. Because you might want to pick a full sketch (although extrude surface says "sketch curves" so maybe that would be better)
2. Because construction entities are for construction only

1. Isn't entity a more broader term, then?
2. in the image here, I only use the splines in 1) to construct the splines in 2). Shouldn't 1) be construction splines, then?

Actually hereunder is an example in which I would prefer to be able to select constructive geometry (with the Beams feature).

Having the lines of the sketches as constructive geometry does not highlight the areas in the sketches and sometimes it is easier to select other entities
