    Question Modeling: Border on either side of a Edge?

    see JPEG:

    In the given situation illustrated, I'd like a continuous border to be created on both sides of the selected Edge loop, one on the flat plane of the object, another inside the depression. But JUST around the green highlited Edges.

    What's the best way to do that? The inside is trivial (Cut or Bandsaw), but the big flat area is baffling me. :stumped

    Tnx!

    But I don't want the outside edge of the big polygon to get a bevel/border. Just the bit around the selected Edges.

    bevel, then select the n-gon and the outer border and merge polygons, then just delete on attached points (easy to select them from the point statistics panel).

    I was going to suggest using Edge Bevel, but I gave it a quick go and it went bonkers. Half went in, half went out.

    Sandman's suggestion sounds best. Bevel it then delete/merge the stuff you dont want.

    Well, that seems to be the consensus.

    I sure wish there was some sort of "External Bandsaw" available.

    Thanks guys.

    Actually, this is all (painful) prep FOR Rounder, since Rounder isn't working for me here on the objects in question.

    I get a variety of errors when I try this w/Rounder, so I'm doing this effect to make it more predictable.

    This can easily be done with LWCad's Mass Offset.

    How I long for the cash to purchase LWCad.

    Mass offset? well Im not sure that will work on native lightwave already constructed geometry and select edges and offset them, working with lwcads tools from scratch completly might be different thou.

    Here's why I'm not using Rounder to get the fillet (chamfer?) I'm attempting. See JPEG. Note the size of the grid.

    Rounder is just too unpredictable, when it works at all. I never know quite what it's going to cough out.

    Agreed ..it is tricky and could be improved, but I think I tested the Lw cad rounder on a certain part that would fail no matter how I set it, but with Lw native rounder that worked very well, so it ainīt all crap.

    I think it might be best to simply bevel polys, merge polys as mentioned in one post above I think.

    Im curious thou, would you mind posting the object file for testing, Im curious if I know some settings in rounder that works wich you donīt know about?

    Edit..worked nicely on making these gym lockers and safety locker (I know to small image on the website)




    And on some cushions on the machines from time to time..



    Cheers

    I didn't save that last object, just whipped it up for testing.

    But here's a thing: after the bad situation pictured, I UNDO'd, and tried again without changing any geometry but RESETting Rounder, and WALLAGH! it worked reasonably. But another inset in the same, uhhh, foundation (that is, a similar indent, so there was two), kept giving me "red line" status errors. I could never get Rounder to work on the second indent. That type of thing disinclines me from using Rounder very much, because I can invest too much time in one part of a model, only to be stymied an hour in.

    Simple situations work best. Although, these were pretty darn simple, just a lot of points.

    Hey Jeric,

    Also, you can use multishift with zero shift.... merge the four polys created around the box border with the big flat plane on top. Really just the same thing as the bevel solution.

    The real issue is that you can only really go as far as the most extreme angle of your "shape" will allow.
    That's a pretty sharp spot on the second example you posted. (see attached)

    Also, you've got a LOT of points defining that curve. Use less (I think you can still get nice curves with less) and you'll have much less headaches (severe angle notwithstanding). With fewer points you can then massage that one trouble angle by hand if necessary.
