2D fillets and CNC

TIG

That works for edges on any plane in 3D space?

I used face.normal since these edges will have faces, BUT you could also use a plane defined by the picked vertex.position and the two edges' other_vertex.positions [plane=Geom.fit_plane_to_points(p1,p2,p3)] and then get the plane's normal=[plane[0],plane[1],plane[2]] ???
Unfortunately this is all from memory...

think I got it working... hmm.... but I don't have much more time today to test this.

Hi all

to answer your question you do not need control over the parameters other than setting the tool radius before you start

so it would be the same every time

hey it would be perfect to have both options to process all and also indervidual corners
can this be done?

I included a DogBone extension in BezierSpline.
This allows to create directly dogbone when drawing a polyline, or to convert an existing contour. You can further change the radius.

So it is not a point and click, and more oriented to handle contours.

It is advised to install first the new upgrade BezierSpline 1.3, because it now converts a sequence of edges without having to weld them as a curve beforehands.

Here is a short video

thanks for your help so much
i did notice that when you apply the dog bone or t bone to a set of poly lines it made them
at every single intersection of polylines which is not what is needed only on the inside corners is it needed as that is where the cutting tool raduis is a problem for getting fits
the cutting tool can make sharp outside corners no problem .
if you take a look at the picture i uploaded you can see which places need dog or t bones in them and which do not
is there way to make the script only apply the t or dog bones to inside corners of a drawing as shown in my picture
i hope this makes sense?

and thanks again for all your help

Sorry, this is not really possible with the current design of BezierSpline.
You can still select the two edges bordering a vertex and apply the script however.

that will work fine. thanks for all your work on this

and to you tig thank you for your work and input as well did you end up finishing anything?

and to everyone els who took and interest thanks much

I've also been looking at this over the last week. Haven't had much time to work on it. (Nor can I do much work atm as my right eye isn't too good.)
But it touches upon something I've been having problems with before, determining the orientation of edges in relationship to each other. So with a milling tool in mind, I started writing a tool that let you click in a face to create the fillets in appropriate corners.

This is still just WIP. Haven't written the code that actually makes the cut.
