I wish to apply a bevel modifier to one edge, and not its two vertices.

Here is an exemple : enter image description here

The bevel is fine on the edge (blue), but it also smoothen the vertices (in red).

How can I avoid that ?

Thanks for any help.

EDIT : Here is an approximation of what i want : enter image description here

The goal is to have a quick and clean process for this.

  • $\begingroup$ with the bevel it is supposed to create several additional edges and I guess in your situation the triangulation is the only way it can do it, you should use the knife to create your additional edges $\endgroup$

  • $\begingroup$ All right. That's too bad since the 'manual' way to do a bevel (knife, ...) is longer and hard to get a good result with... thx anyway $\endgroup$

  • $\begingroup$ there's another way if you select the edges and subdivide, I'm going to answer with pictures $\endgroup$

  • $\begingroup$ Really wondering why You need this? It makes NGONS which are pretty bad so Im just curious mate... $\endgroup$

  • $\begingroup$ I agree ngons are bad. This can be solved with an aven amount of bevel sides ; or with the same amount of triangles as above, but aligned. For the why, i need a few of these to join perfectly when put against. $\endgroup$

I don't think you can avoid this triangulation with the bevel tool. But you can add edges with knife, or, easier, with a simple subdivision: il will keep your edges parallel, you'll just have to guess the good distance between them when you'll slide them:
