What constitutes an "edge"?

Consider this simple shape:

Why does Onshape show the intersection of the fillet with the flat surfaces as edges? It looks like I cut a tiny bit too deep with a mill.

I want the actual edges to show, but not the intersections of the fillet, which should be invisible.

    This could be remedied with an option like SolidWorks has to show tangent edges as visible, phantom, or removed. I prefer that tangent edges display differently than a non-tangent edge.

    In CAD the perimeter of any face is considered an Edge .

    to expand on what adrian said:


    This is a basic concept to learning solid modeling. Vertices, edges & faces make up a solid model.

    Truth:
    -every edge has 2 faces (at least in pro/e)
    -vertices can have multiple edges
    -a "solid" is a volume defined by a face or faces (once again pro/e)

    While this may seem trivial, these 3 little nouns hold all the secrets to solid modeling.

    This is so fundamental to what's going on here, you'll appreciate the importance more as time goes on.

    Mastering these 3 nouns:




    My vote, I want to see the face edges in the brep definition. Please don't take those away.

    The improvement request here is not to take these away, it's to represent them slightly differently so that you know they are tangents edges.  Like this:

    Representing the tangent edges as PeteYodis illustrated is a good idea, I think, but I'd also like the option to not show them at all. My objective is to be able to render a more photo-realistic image.

    @jon_woellhaf -  Is this what you are after?  Choose 'shaded without hidden edges'

    No. Close, but this view softens details too much and seems to blur the image.

    you may want to check out the App Store for rendering add-on.

    I hadn't thought of that. Thanks, bruce_williams. I'll do that.
