    I just realized I've hi-jacked this thread and turned it into a curve discussion, sorry.

    Bridge curves will pickup the mid point of an existing curve. 3D curve (3d fit spline) will not:


    So, one of the reason's I liked Ilya's 3D spline feature script, with my modification, I could pick the mid point of another curve. This is something I do a lot when creating planar faces on mesh data. But, can I stay in native code without feature scripts?

    planar face on mesh:
    1. construct 2 vectors
    2. sweep one vector along the other
    3. extend surface edges beyond working area
    4. sketch your stuff
    5. offset 0mm to create a trimmed surface

    I used a modified feature script but you can use a bridge curve and create 2 vectors:


    Sweep to create a plane:


    Extend surface to make plane usable, this is a feature script:


    Use this plane to create a sketch:


    Create another sculpted surface (trimmed surface) from sketch:

    I went from mesh data to a planar face which is the start of a part. Notice the 2 vectors (highlighted curves) are co-planar to my sculpted face. This is repeated several times to stitch together the beginning of a part.

    This is an example of surfaces migrating into solids.

    @billy2
    You can use this feature to extrude a line in a direction defined by two vertices, rather than having to create another line to sweep along:

    @mbartlett21 nice! I've been looking for thins and you've brought them to onshape. It's in my tool bar.
