Dogbone dressup not on one corner

[chrisb]

Retested with the version below and it still works:
- load file PathTest_13c.FCStd
- mark DogboneDressup for recompute
- recompute
and there it is.

Perhaps it is a precision issue, I have set tolerance and accuracy both to 0.01mm.

Thanks chrisb.
I'll play around a bit more and see if I can track down what is causing my problem

Use "Adaptive" - it works the way you want.

Thanks for replying.
I haven't got as far as looking at Adaptive yet. I'm still working my way through the dressups.
The only problem I can see with your suggestion is that the tool will spend most of its time rubbing already machined surfaces whether I do a Contour before or after Adaptive.

The Dogbone looks more efficient and appears to work almost always after a recompute.
I have had problems with FreeCAD crashing when deleting a Dogbone and it doesn't recover.
Also I have experienced different things occurring a couple of times, but they aren't repeatable enough to document. eg twice simply double clicking the Dogbone dressup without doing a recompute has fixed the Dogbone.

I need to spend more time investigating because I think the dressups will be very useful.

Sorry for the late reply, I created a PocketShape with an extension and I think the result is quite nice. Added a Profile to make sure the square gets milled correctly though. Note that if you want to make absolute sure you can make the extension wider. By default it extends by half a tool diameter.

Apologies for the perspective view - I don't know where it came from and have trouble turning it off again.

Interesting - extension option was under my radar so far. *top*
