Hi Rentlau_64,
Thanks for your work.
I've installed the last version and tried the new cutting tool but I 've an error... but I don't know why

ThierryM,

Yes I got the same error message...
You need to define a plane extending outside object limit (ie one of the Planes of the object's bounding box) and a line also extending across the object to cut the object in two parts.

Thanks Rentlau_64 for your explanations and the corrections on my file.

Thierry,

In fact you pointed a lack in my cutting tool...now I corrected and even with your first file we are now able to cut the Cone.

I will put the fix on Github soon.

Rentlau_64,
Happy to have pointed a lack... involuntarily

Hello everyone and thanks for your excelent work improving FreeCAD. This WorkFeature is excelent and very productive.
I have some questions:
- I can´t find the cut tool when I install this Macro.
- How can I proyected (or an intersection) a point created in 3D view in a Sketch for work in it? I can proyect it in a plane but when I do a sketch in this plane I can't access to this point for work with it .

Thanks again!!

JoseAntonioGutierrez,

If you get the MACRO from https://github.com/Rentlau/WorkFeature.git

You migth find the Cutting tool in the Modif. left tab (last one on the left)

Yes I know and I do not have any turn around right now to transform a Point into a Sketch point???

If someone know how to do it I can inroduce this useful function into th WF MACRO

Hello.

Yes I know and I do not have any turn around right now to transform a Point into a Sketch point???

If someone know how to do it I can inroduce this useful function into th WF MACRO

I worked at this some time ago, this is what I have:

Code: Select all

Sk = Gui.Selection.getSelection()[0]
Point = Gui.Selection.getSelectionEx()[1].SubObjects[0]

rec = Part.makePlane(1,1)
rec.Placement = Sk.Placement
recN = rec.normalAt(0,0)

VpP = Point.Point

Projection = VpP.projectToPlane(Sk.Placement.Base, recN)

Select a sketch, one point of an object and copy-paste at command line.

Variable "Projection" contains the coordinates of the projected point over the sketch plane.
If someone knows how to convert this to local sketch coordiantes( X,Y,0), you have the tool.

JoseAntonioGutierrez, Javier,

Thank you Javier for your answer, I guess I found to complete your piece of code;
So JoseAntonioGutierrez, when you want to transform a Point created by the WF MACRO into a Sketch Point you need the following command:

Code: Select all

# Select a Skecth first and a Point on the view

# Get the Sketch from the selection
Sk = Gui.Selection.getSelection()[0]
# Get the Point from the selection
Point = Gui.Selection.getSelectionEx()[1].SubObjects[0]
# Get the Sketch Plane info
rec = Part.makePlane(1,1)
rec.Placement = Sk.Placement
recN = rec.normalAt(0,0)
# Get the Point
VpP = Point.Point
# Projection of the Point selected onto the Sketch Plane
Projection = VpP.projectToPlane(Sk.Placement.Base, recN)
# Build a geometry list
geoList = []
# Append the Projection
geoList.append(Part.Point(Projection))
# Add the geometry list to the Sketch
Sk.addGeometry(geoList)

I will add buttons into the WF MACRO for all piece of geometry created in order you can transfert them into the Sketch selected.

Bonjour Rentlau_64,

Great Effort!

This MACRO:WorkFeature is "da bomb". If you dont know this expression, it is slang for, how you say (please excuse my French) La Meilleure Macro, No?

Not only is it nicely designed, functional, and productive, it provides a great tool for doing ad-hoc measurements and alignment checks at your finger tips without digging through multiple buttons and screens. It is a great tool for those people (including architects and engineers) not versed in FreeCAD.

It works well; check following.

User:rockn is right on track concerning the organization/management of MACROs; there needs to be some kind of Macro Installation "Convention" or "Best Practices" to manage files/folders to mitigate the duplication of similarly names.

If not too difficult, is it possible you might consider including; IsParallel, IsPerpendicular, and IsSamePlane, to quickly check object alignments during model analysis and assembly/placement.

For button labels, I would suggest relying on the "hover description", unless required, as is done in the rest of FreeCAD; small and concise.

Did I mention Great Effort! Cant say it enough!
