Part Connect failing to merge wires together into a singular one

[SpeeQz1]

Following the tutorial Cogset Tutorial and making a very basic example, I couldn't get the wires to connect as they kept failing due to errors:

11:38:58  pyException: Traceback (most recent call last):

according to the error message, the sketch has some stray vertices. From your screenshots, it looks like there is one at sketch origin that is not construction geometry. Try deleting it, or toggle into being construction geometry.

had to remake the sketch but I checked the vertices and there isn't any free one yet the part fails again:

I guess, it might be some new behavior of FreeCAD here that i'm not quite familiar with. I can open your file in my older FreeCAD, and change all the line ends into construction, and then the populate can be connected.

If that still doesn't work for you, Lattice2 Downgrade to Wires then Connect works.

Both solutions seemed to have worked so thanks. But it would be good to take a look into somehow fixing this so that normal points can be used.

So, in FC v1.0, standalone vertices created in Sketcher follow the the state of construction mode toggle, just like all other geometry. I'm closing this as it is not a Lattice2 issue; i might even say it is not a bug at all. Basic features like Part Extrude are also affected by these vertices.
