Hay people some challenge!!
Need to find the easest and simple way to make this:

Hi Andrei, at first I thought you'd just make a large 3 sided cutting surface and slice the full object with that.

But it looks like you want to have a controlled strip that comes more from a chamfer, but only a portion of the chamfer. So probably what I'd do in that case would be to do an actual chamfer, then select the chamfer face and do Ctrl+C to copy it to the clipboard temporarily. Now undo to go back to your original shape and Ctrl+V paste in the chamfer face.

Now slice the chamfer face using Trim with the "Isocurve" option to extract out just the region of the chamfer you want to keep.

Now draw lines from the end of the chamfer piece onto the main shape's edge, you now have 3 sided areas to fill in with Construct > Planar, join the chamfer and the 2 triangle pieces together to make your cutting surface and then use boolean difference to slice the main object with that as the cutting object (or use Trim).

Let me know if you are stuck on any of these steps.

Hi Andrei, actually I guess you shouldn't form triangles on the end because the side surfaces are not flat and if you just draw in a straight line it may not hug the surface well enough to cut it.

So instead of a straight line here:




Put in instead a 3 point plane surface (Draw solid > Plane > 3pts), snapped on to these 3 points:




So your cutting object would be the chamfer fragment and then one of those 3 point planes on either side.

I used flow. If I wanted to keep the 45 angle, I would scale the bottom points of the triangles out before I do the loft, so they do a complete cut without the history adjust.

Sorry what was the first file system of download ?
Some problems with it! Some difficulties to install etc...
Why don't send a simple .zip with a normal host ?

So I have not the example file for try something :)
But seems i will make a simple sweep + Boolean Diff

Frenchy,
When you first navigate to the file, look for the checkmark for "use our downloader" and uncheck that... Don't install their downloader.

too late... that makes some disturb on my browser!

And difficulties to remove it! :)

There goes the rest of your day!!!! :(

Never need a downloader... They are marketing tools.

Thanks guys, Michael interesting idea with chamfer and undo, I made chamfer surface using isocurves in my example. Burrman good idea but looks a bit complicated for me, I use Flow very rarely, it seems to me a bit complicated :) Anyway thanks.
I found today another method that is very fast, you have to set CPlain from view and then cut it. Very simple method but you have to go to ortho view and find good angle to cut.

Pilou, did not know about that stuff, just looked at download page, yes you have to uncheck - use our download manager. There was no this thing in the past :)

No problem but I am sure that a lot of people make the same error than me! :)

Pilou, did not know about it) This is new link: http://we.tl/qrvg08iiMM

Thx! this one was more clear! :)

Like seeing different methods, here's another.

Bravo DannyT, very cool! thanks!

But one thing! How to control angle of this?

Just found, some how it can be controled via chamfer. May be there is onother way to control it?

Maybe with this ?

Hi Andrei,

> But one thing! How to control angle of this?

One possibility is if you shoot a 3 point plane coming straight off that chamfer segment edge, you can then select it and use Transform > Rotate > Rotate axis to pivot it by your specific desired angle.

The "rotate axis" transform allows you to pick any line as the rotation axis and your object will pivot about that line.

Just make the plane long enough so that it sticks all the way up through the object after it has been rotated.

Thank you Michael good solution!

Pilou Im not sure I understood your method.
