Best wishes from Germany.

It's done. The interpolate tool now has a "polygonal" property that interpolates to a degree 1 bspline curve.
But if you plan to use it as a sweep path, maybe a wire output would be better ?

Thank you so much Chris. If it's no big thing, please add the possibility to choose between bspline- and wire curve.

Thank you so much Chris. If it's no big thing, please add the possibility to choose between bspline- and wire curve.

I have added a "WireOutput" option, that appears when "Polygonal" property is set to True.

Thank you very much Chris. Very nice.

… is there anywhere an explanation what the commands

• to console and
  BSpline to console

are doing or what their use is?

[Chris_G]

to console and
BSpline to console

"to console" gives access to the selection in the python console.
It is the same as right-clicking an item in the Selection View panel and choosing "To python console", except that my version works on multiple selection.

"BSpline to console" works with a BSpline edge selected, and outputs a piece of code in the python console to create this curve.
Both tools are mainly development tools for python scripting.

Hi Chris_G,

I have just a little question about "Join Curves".

Here we have 2 profiles for later lofting:
a top side circle
and a bottom side rect, joint together with "Join Curves"
As well known, we have to control the start point of engaged curves to get a predictable result from loft.

red point well located:

red point bad located

AFAIK, one can control its location with choosing a specific selection sequence of segments which should be joint.

But it's really counterintuitive and needs several attempts until a usable config is found

If property "Forced Closed" needs to be set to true, because of gaps between the segments, some endpoints not are not reachable by changing
selection sequence

There should be a workflow for setting this point explicitly.

Hi,
Can someone outline how to add the curves menu to the the WB? I have installed version 0.17 on Windows 7.
Thanks in advance.

Hi Hooshsim, welcome here.
Menu->Tools->Addon manager. Select Curves from the Workbenches list and click Install/update. Terminate FreeCAD and restart again. Curves will be in th elist of workbenches.

Sweep two rails doesn't follow profiles. What I messed up?

Sweep2Rails doesn't work on Wire Profiles, but only on profiles made of a single edge.
So you need to join each wire first.
