Curves workbench

[Chris_G]

Give a try at this one :

Code: Select all

edge = FreeCADGui.Selection.getSelection()[0].Shape.Edges[0]

sk = App.activeDocument().addObject('Sketcher::SketchObject','Sketch')

sk.addGeometry(edge.Curve, False)

# Sketcher magic fonction :
sk.exposeInternalGeometry(0)
 

It seems that Sketcher has a "magic function" that adds all the necessary geometries and constraints ...

Thanks a lot Chris!!!
Great coding as always!
I will update my macro.
I think this would be also a nice feature to be added to your Curves WB!

Thanks again

You're welcome.
I learned new FreeCAD tricks today !

Hello Chris_G,

some days ago i encountered that "Map sketch on surface"

Map Sketch on Surface.png (9.75 KiB) Viewed 3371 times

doesn't work anymore.

Not even with "FreeCAD\Mod\Curves\TestFiles\Sketch_on_surface.fcstd".

Report view shows only:
Please select exactly 1 face and 1 sketch

I can't remember exactly, but i thought i've seen this working in the past.

Searched forum, but no results

Do i miss something?

Tested with:

Hi,
It works here.
The face must be selected in the 3D view.
The sketch can be selected in the tree view, or by one of its edges in the 3D view.
I suppose you are selecting the "face" object in the tree view ...

Oh, sorry, my bad!

The face must be selected in the 3D view.

That's the detail i didn't remember

A hint in error message probably can prevent from blocking innocent user (like me).

Please select exactly 1 face and 1 sketch (IN 3D VIEW)

Done. Thanks.

If I try to change into the curves-wb the following message appear:

I installed the curves-wb via addon-manager.

@Chris_G, please let me know if it's possible to create the selected green curves tangent to the edges of the two solids with your curves workbench, like to see in this picture:

I created the curves in Pro-Engineer Wildfire 5.0.

The file for to experiment with, you can find here:

Hi,
I just tried renaming my .FreeCAD/ folder and installed the WB with addon-manager.
I get no error ...

@Chris_G, please let me know if it's possible to create the selected green curves tangent to the edges of the two solids with your curves workbench, like to see in this picture:

There is the "parametric blend curve" (6th icon).
- it takes 2 edges in the 3D view as input
- set the continuities to G1
- Parameter properties move the endPoints of the curve
- Reverse properties to reverse the orientation of the tangents
- Scale properties modify the "strength" of the tangent

Whow Chris, you are my hero. Thank you so much. This is a great and helpful feature. I renamed my .freecad folder in Xubuntu, created it new by starting Freecad and installed the curves-wb via addon-installer. Here you can see the amazing parametric blende curve on my example model:
