Re: Curves workbench
...first try => it looks a little bit weird
Re: Curves workbench
...PipeShell apparently does not like the "Slot-Feature" in sketcher.
I used an actual example out of the german forum. (flattened pipe)
Using only circles in sketcher the feature works as expected and parameters can be explored.
Sorry for the bad start.

Re: Curves workbench
...and it works with BSplines .
Is it also usable with open profiles?

Re: Curves workbench
It is usable with open profiles.
It is a "Part.Sweep" with more options.
So it should be able to do everything Part.Sweep can do.
I don't know if this tool will be really useful, but at least, it offers an easy way to explore the different options.

Re: Curves workbench
Hello,
Wow, what an incredible work here!
I've installed this WB.
But: I am new in FreeCAD world, and I've seen screenshots here and there with other amazing curved stuff, and I wonder : do I need this WB to my project? Or is there something simpler in my case? And, I am with v16, I heard v17 does more with curves but are there commun points/differences with your great Curves WB?
Thank you!

The workbench is not tested with 0.16, and I know some tools won't work with this version.
I'll go there for further discussion.Stéphane Combet wrote: ↑Fri Apr 27, 2018 12:46 pm (my project: molds for a personnal RC sailplane, https://forum.freecadweb.org/viewtopic.php?f=12&t=26757)
Re: Curves workbench
Just played a little bit with "sketch on surface", immediately coming up with a question.
How should a sketch looks like, to fit onto a cone?
outline didn't fit to cone's face. Seem should be a straight line, shouldn't?

Re: Curves workbench
Hi,
Every surface in FC (and I suppose this is the same in every CAD software) has a rectangle topology: its parametric space is a rectangle that goes from (u0,v0) to (u1,v1).
Code: Select all
Cone.Shape.Face1.ParameterRange
>>> (0.0, 6.283185307179586, 0.0, 107.70329614269008)
Then set to True the properties "Construction Bounds" and "Scale" of the Sketch_on_surface object. In your cone example, you'll see that the upper edge of the bounding square degenerates to a point ( the tip of the cone ).

Re: Curves workbench
Oh, yes, i see.
Many thanks for clarification!
Unfortunately its a non conformal transformation , even if surface is developable.

Re: Curves workbench
Some support also spherical/polar coordinate systems. this can probably change the results of that kind of curves...Chris_G wrote: ↑Sun Jun 24, 2018 8:18 am Every surface in FC (and I suppose this is the same in every CAD software) has a rectangle topology: its parametric space is a rectangle that goes from (u0,v0) to (u1,v1).Code: Select all
