Dear All
First of all, thank you for very useful forum.
I am new here and in SW, so let me bother you with stupid question

I have sheet-metal object "Dog-Kennel" and is necessary to bend it around Ø16mm tube.
File is attached.

If you have any suggestions please help.

Thank you in advance

Correct Answer

What part do you want to follow the contour of the round bar? Just the legs?

    Probably the easiest way is since you sketched the hat shape and made that your base flange, then just modify that sketch by putting in a reference circle of the 16mm dia. and make the legs match that. Done deal.

      Ok, but than, how can I keep "width" of legs?
      I mean, now I have lines (4mm) and you think I should have ARCs instead?
      
      thanks

        You are correct in that you would have arcs. If 4mm length is your critical factor, then put an arc dim on them to drive their length. If you want a particular length in the flat, then go that route. If you know that really you want a particular degree of wrap, then dim it that way.
        
        Either way, make sure you properly set the k-factor for those arcs (50%) vs. the 90° bends (probably about 37% or so).
        
        Keep asking and trying until you get what you want - don't give up. We'll still be here. :-)
