    Is there a Band Saw Pro with Smooth/Metaform?

    Is there a tool that does a bandsaw split on a loop and then adjusts the points to make a smoothed/metaformed curve with adjacent polys in one step?

    Normally I bandsaw and then maually size or tweak the points to follow the curve where I'm adding new geometry - It would be nice to save a few steps and have that in one tool. I have LWCAD but I dont know if it has anything like that - so I tend to just use Band Saw Pro...

    If what I'm asking doesn't make sense I can put up a picture of what I'm after. Thanks for any ideas.

    Yes, a picture or series of pictures would help.

    In the meantime it kinda sounds like your talking about a mix between creating edges with Detail Tab>Edges>Edit Edges and Multiply Tab>Extend>Multishift.

    I could be wrong though.

    Yes. It is called Swift Edge Loop.

    Bear in mind, if all you want to do is to create new edge loops, slide them up and down or delete them, then Edit Edges will do that. And you don't have to pay $50 for the priviledge.

    Just sayin'.

    an alternative could be using Chamfer.

    run Chamfer once,
    then one more time.

    example >




    note; not 100% the same, so Swift Edge Loop might be the way.

    (sorry, misunderstood issue, fixed now)

    Sensei, I'm not sure I understand how SwiftEdgeLoop lets OP conform the resultant edge to a curve, can you explain that better?

    Erik, as an aside and without hijacking the thread (hopefully), why didn't you just bring the line segment straight out so it met that vertical edge at perpendicular, instead of at an angle (see below)? That seems like it'd guarantee a clean result even across multiple chamfers.

    long time ago, as far as i recall it produced a less good result. i'm pretty sure i tried it.

    Yeah, figured it was a while ago, just wondered. I'd be a bit concerned if a perp. intersection did worse than a more/less acute one (90deg angles have simple mitering geometry compared to more/less acute), but definitely possible.

    I don't think so OP meant curve = Catmull-Rom curve..

    I showed on screen-shots in this thread:

    quick'n'easy smooth sub-patched mesh with relatively low-poly.

    You have mode in GUI, percentage or metric.

    It also obeys user polygon selection, so edge loop (Band Saw Pro does not)

    It also has option to preserve curvature of original mesh.

    It is all described on the website...

    Ah okay, if he just meant maintain or adjust curvature of sub-d then, yeah, SwiftEdgeLoop is a great option (esp. as it will maintain curvature if desired).

    Yes I meant the shape based on normals of adjacent looped polys... So it seems as Sensei's tool is kind of what I'm after. I might wait until he has a Black Friday sale though (hint hint)...

    Yup, I don't do sub-d anymore since I'm all about the realtime and Unity now... Kind of miss sub-d though... Just low poly for me these days.
