Please integrate new features into old tools like loft and sweep

[freecad-heini-1]

Guten Tag,
last days I played a bit around to design complex mold inserts for injection molding. One task is to create parting planes.
I can say that Freecad is very powerful in designing such things. With split / slice, the Surface workbench and boolean operations I'm able to create complex parting planes. From my point of view Freecad plays in the same high level like the Top5 cad systems concerning mold design. I'm really impressed. I think about to create a demo video to show how powerful Freecad is concerning this matter.

I'm a friend from Lattice2 sublink. It creates copy from faces and edges, and they are full parametric.
The bad thing, Loft ignores this nice features.
Copy from edges are Lattice2 "subelements" If I convert they to joincurve Loft accept it.

For example, I copied these edges to create a loft face:

parting_plane_loft_2.png (170.25 KiB) Viewed 1007 times

The result should look like this:

parting_plane_loft_1.png (109.11 KiB) Viewed 1007 times

Loft is much better than ruled face for such operations, but it didn't accept sublink features.

My wish is to modernise tools like Loft and Sweep that new features are useable.

Please let me know your thoughts.

Best regards
Wilfried

Yes, please! A video on that will be nice.
Thanks!

For example, I copied these edges to create a loft face:
(...)
The result should look like this:

This does not seem possible to me. The outer edges generated from the start profile (the green selected edges at the top) to the end profile (the selected edges at the bottom) should be straight, not rounded. Wouldn't a boundary surface tool be better suited here? As far as I know you can already do this with the Surface workbench, and the result is parametric.

Otherwise, to get a Loft with the orange patch in your picture, the Loft tool would need to support guide rails.

Hi Normand,
my question is, why is subelement from Lattice2 workbench sublink not supported with the part wb Loft tool?
JoinCurve from the curves wb is supported.

Here a video for you:
