Followfy 0.2 (2014-05-15)

Aaaaaaaaaaaaaah !

And this also don't work because I don't put it at the extremity!

Now all is fine!
Advantage against the FollowMe in this case: select by triple click!

Nice tool, Caul.

@Pilou: "Followfy is meaning something ?" Straightforward answer is similar to the suffix in Quantify- which means apply a quantity to. Or Signify. It's a somewhat informal attachment commonly done in English, but new for the word follow.

Great! could have done with having this yesterday as I had a component in a model that 'follow me' just wouldn't work on.

Great addition to the toolbox

@Mitcorb Thx!

CAUL,

Having written a similar plugin almost three years ago, I was very curious as to how you did yours. About the only similarity was the projecting of points on bisecting planes at the corners.

It is impossible to test for all possible things that could go wrong so when I seemed to find a situation that causes a failure in the mergeCoPlanarFaces method, I thought you might like to know.

Left clicking anywhere in the model causes this results to appear.

Adding the next statement eliminates the failure but typically, collecting the edges to be deleted and deleting them after all edges are processed, usually works best.

    es.each { |e|
		next unless e.faces[0] && e.faces[1]
        vs = e.faces[0].vertices + e.faces[1].vertices
        p = Geom;;fit_plane_to_points vs
        cop = vs.all? { |v| v.position.on_plane? p }
        e.erase! if cop
    }

Interesting, how did you approach the problem?

Thanks for the feedback! The mergeCoplanar-method was/is a disaster waiting to happen. I will release an updated version soon.

May I ask for a modification/addition? Would it be possible to have it also Smooth/Soften curves like the native Follow Me tool does?

That's on the TODO-list.

ps Maybe an info Message "Followfy is calculating" will be fine for complex path/profile !

As it happens, almost all time is spent trying to build the geometry with the api method add_face. In this release the geometry is built with triangles. The next release will use rectangles when appropriate (which is almost always) and that will roughly double the speed.

It is called Edge Follow Me and can be found in the plugins store. It was written in request of a tool that would use an edge/curve profile and do an extrusion.

Thank you very much, what a great plugin!

Followfy is remarkably more solid than native followme for any tested planar nonlooping path.

Please consider adding solidsolving for non-planar paths.

Nice! Great plugin.
