How To Model this Solid

[AtD]

Hello All,
this time I have a fairly simple question. Is it possible to model this body in FreeCAD? I have 3 sketches, a triangle left, a triangle right and on the horizontal plane its a piece of an arc as path to extrude. The path end points are coincident to the triangle verteces.

Normally I would have searched for it first, but I don't know what this would be called, so excuse my lack of research.
I have tried using the Sweep tools in PartDesign and Part, but it seems to be impossible to use with two sketches that have coinciding edges (the vertical edge). Another tool didn't come to mind.
Happy for any suggestions!

My 2 cent:
Create sketches
Create surfaces with surface-wb
Convert surfaces to solid with curves-wb

I think the solution is very good. it is a nice example of the suggestion that curves should be included in the freecad basic system.

Nicely done. Thank you. I was not fully aware of this option.

I wish there was a more directy way though. I know you guys are tired of comparisons to other CAD systems, but Solidworks' Sweep tool is able to go with these inputs and create this in one feature. Actually, I need to cut this kind of shape out of another, which then takes me quite a huge amount of features just to cut away a piece. However, I am happy it works at all.

As for other CAD software, yes, you are correct, many are just tired of the comparisons...

To quote one of the "small team of developers" and founding member:

Yorik: "FreeCAD has a very small team of developers. We have not as much time as we would like to dedicate to FreeCAD, and things are not planned ahead, they are done when some developer sees it fit and when he finds time to do it. So we don't maintain a list of tasks to be done. It is up to you to find something you would like to do, for example a defect you would like to correct, or a small feature you think is missing."

As for the example offered...
Unfortunately, the Solid created fails Geometry check.

Indeed.

But, why can you extrude or loft to a point in Part, but not in Part Design?

I would use the simplemost tools: Cone+sketch based pocket.

The attached file passes geometry check.

For generalization with PartDesign_AdditiveLoft :
* sketch at the bottom
* the same sketch at the top but scaled to something really small.
* Additive loft
