 Does it possible to have a regulate who give a perfect angle of 90° (not rounded) ? Attachments:

 2309.2 In reply to 2309.1 Hi Pilou, Blend is meant to create a smooth surface - an object with a perfect 90 degree angle in it will have a corner in it and will not be smooth, so it won't work as a Blend. Normally to put in something like that you would just draw a couple of polylines and then use Construct/Planar to build a planar surface from the outline. If you like you can also select 2 edges at a time and use Edit/Extend to make extended lines where they intersect one another, like this: - Michael Attachments:

 2309.3 In reply to 2309.2 Ok I had expected that exist a special Tangent (G1, G2,....) or Curvature :) Of course it's possible with another methods but with some steps ;)

 2309.4 In reply to 2309.3 Hi Pilou, > Ok I had expected that exist a special Tangent (G1, G2,....) or Curvature :) Those options for Blend are for how the Blend surface behaves where it touches the other edges, I mean at these areas here: If I understand you correctly, you're asking for an option to have the "Blend" surface be G1 at those edges, but have a sharp crease in the middle of the surface instead? Basically Blend will not do that job - Blend basically assumes that the blended surface itself is a smooth surface object, to make a creased object you will need to use other commands for that. - Michael Attachments:

 2309.5 In reply to 2309.3 Hi Pilou, > Of course it's possible with another methods but with some steps ;) Yes, just as many steps if there was a 90 deg blend function ;) 1.Plane 2.Rectangle 3.Boolean, Diff :) Cheers ~Danny~ Attachments:
