Curves workbench

[Chris_G]

Hi all,

If your feature for 3D-BSplines would work, maybe "some people" would be happy.

I have a little feature request:
Would something like this be hard to implement
If one will have lots of Sketches linked to lots of Profiles, they are really hard to maintain, especially if there are only small differences between the involved shapes.

I don't have much free time these days, but I will put this on the todo list :
- Parametric BSpline curve interpolating a group of vertexes
- make the Pipeshell_profile tool able to work with document objects (currently it works only with list of edges )

Hi Chris_G,
I have also a feature request, it concerns the possibility to snap to imported point cloud and create a bspline out of the points.
...
I wish to have a 3D spline to select and snap points in 3d view and create a bspline out of the points.

If I make a 3D BSpline interpolating curve first, then we would only need a little tool to convert a point cloud to vertex cloud object.
This one should be easy.

There's really no need to hurry

Perfect. Thanks !

Whow, that is great. Thank you so much Werner.

@Chris_G, no problem if you have not time. I can wait.

I added a new tool to CurvesWB.
It is a sublink editor (icon above the mouse pointer).

Some parametric objects use "PropertyLinkSub" and "PropertyLinkSubList" properties to link to a subshape (Vertex, Edge, Face) or a list of subshapes.
These 2 types of properties don't appear in the Property View. I had no way to change them ( except with python console ).

How to use:
- select an object (that has sublink properties) in the Tree View
- activate sublink editor
- a widget appears with the list of sublink properties, and the selected object disappears (to have clearer view of the subshapes)
- the View button temporarily shows the current link
- select another subshape and push the set button to change the property.
- Quit to apply the changes

It may also be useful to fix a toponaming issue.

You can try on the Ruled surface of the attached file :

Hi,
Thanks for testing.
Any message in the report view ?
On what kind of object did you try (the ruled surface of the attached file, or something else) ?
We are running the same system, so that's pretty strange.

When I try to load the workbench using one of the python3 / qt5 conda builds I get this error message in the report view:

name 'reload' is not defined
Traceback (most recent call last):
File "<string>", line 46, in Initialize
File "C:\Users\mwganson\AppData\Roaming\FreeCAD\Mod\Curves\ZebraTool.py", line 7, in <module>
reload(Zebra_Gui)


And a window pops up saying something about loading the workbench failure, name 'reload' is not defined. None of the toolbar icons come up. Neither does the Curves menu.

Edit, forgot the info:

2nd edit:

After uninstalling the workbench, then reinstalling to get the new feature, I get this error:

Missing parentheses in call to 'print'. Did you mean print('accept and resetEdit')? (sublink_edit.py, line 103)
Traceback (most recent call last):
File "<string>", line 65, in Initialize

By the way, in the following version of FreeCAD, the sublink editor seems to work just fine using the ruled surface as the test object:

First time you use python 3 and for python 3 reload see
https://stackoverflow.com/questions/182 ... ort-object


For the second i think it's weird rhat it complaint about parentheses since also that is python 3
