Re: Patch #2864: PathHelix x10 issue on "Step in Z" inputfield and "Step in Radius"

Should be fixed by git commit 8a4952044. I just made a pull request for this.

Turns out a locale independent solution is to use the UserString attribute of Quantity as input for Gui::InputFields setText() method.

Problem with Gui::InputField property "quantity" using python (and possible locale issue)

Hi there, I am having trouble using the nice unit-aware Gui::InputField widget from python. I can query the "quantity" property just fine: >>> widget = ui.createWidget("Gui::InputField") >>> widget.setText("1 mm") >>> q = widget.property("quantity") >>> q 1 mm However, it does not seem possible to s...

Re: Helix machining for circular holes

Thank you all for testing this!

Meanwhile I have also reworked the task panel a bit, it now also uses a QToolBox based layout to make it more consistent with the other Path operations.

I will submit a PR shortly, based on my commit f2faa5080.

Kind regards,
Lorenz

Re: Helix machining for circular holes

I was able to drop the requirement of scipy, see my commit 1edc151c5.

Maybe a windows user could test this before I submit another pull request?

Re: Helix machining for circular holes

Hello lorenz, Thank-you for this! On Win scipy is a real show stopper. With no opensource or even free Fortran compiler we have no good way to support this requirement. We do support numpy if this helps. If numpy is OK as a dependency (it seems, numerous FreeCAD scripts require it) I could probably...

Re: Helix machining for circular holes

wmayer has merged the PR but I think this needs some additional work. My biggest concern is that it adds a dependency to scipy which is pretty heavy. If it's not present, the operation will throw an error and not work at all. If the same functionality can't be done with occ, we should be looking fo...

Re: Helix machining for circular holes

If you decide to integrate it somewhere, please, do not call it drilling, that is a completely different operation.

Helix machining for circular holes

I updated my code for machining circular holes with helicular paths (see also the old discussion ). I made a pull request for this, see https://github.com/FreeCAD/FreeCAD/pull/417 . Compared to earlier versions I removed the feature to automatically detect "counterbore" holes. Currently it seems tha...
