I updated the first post with some info on Loft and Sweep support for multi profile sketches.

I am wondering if this information is correct or compleat. Might it be that the underlying code update has had impact on other functions than Loft and Sweep.

The linked post mentions a pipe function, is this the arch_pipe?

Are the changes in this regard tied to Part or PartDesign or is it both.?

I have not been running 0.17 lately, so I am a bit uncertain. Any info anyone can provide will be updated in the post.

You can edit your own posts, you only have to be a moderator to edit other people's posts. :)

My intention was to offer other people who already has editing privileges (such as yourself) the possibility to do so. I think it is important that the information is as up to date as possible now that DeepSOIC pinned the topic :D .

The proper way to do this is to make a wiki page. I'm soo lazy.... :oops:

If i understand the purpose of this thread correctly it is more about building momentum around FreeCAD 0.17 than anything else. Therefore in my opinion currently this is forum and not Wiki material.

Forum is good for me, because I see immediately the "unread symbol" can look at the entry and can hopefully learn something new again.

I have read the posts under this topic, have rebuilt several of the projects shown here and learnt already some basics about the new concept of Part Design Next.
With this post I would like to go the other way: I have this model for a car's door lock, which I would like to discuss here in order to learn how to improve stability in terms of parametrization. And so I would like to hear your recommendations how to achieve this task.
It has a linear dependency graph and is supposed to be fully parametric. However, it brakes very easyly, even if I make only tiny changes. E.g. if I change in the basic Sketch "Sketch" the distance of the holes at the right from 37.8 mm to 38mm. Here is not the place to discuss this topic, but the reason is, that with the change a renaming of faces takes place - although I don't understand why, because it seems as if all relations stay the same.
Anyway I hope to learn something about Part Design Next.

Any idea concerning the topological naming problem in doorlock.FCStd?

For this special problem I have found a solution: I don't use the equality constraints on the circles any more. Instead I use expressions making the diameters slightly different (1/10000 mm).
Since this is only fooling the topological naming I still would like to see a possibility to solve the problems with the new 0.17 possibilities.
