Edit path of sweep in Revit 2021

[andreas.weber_rkw]

Hello there,

I am facing a difficulty in editing the existing path of a sweep, as it appears to me that the workflow of editing sweeps has changed since Revit release 2021.

Problem is, that when editing the sweep I pick the path, it is then highlighted and i can change the length of a path segment for instance, but i cannot select an endpoint of the path segment to align it to a reference plane. Instead I can pick a 3D edge (previously created model line), but when I delete the original path segment hosting the profile plane, the profile plane moves arbitrarily to another path segment and messes up the alignments of the profile.

Which is the proper workflow to edit an existing path and aligning it to ref planes?

Thank you for your hints.

Unfortunately I can't correct my spelling mistake in the title. This is going to be my next question 😉

I do not believe they introduced a dramatic change in 2021...if you created the sweep using pick 3D edges it is locked to those edges, that's the idea of it. Locking it to a plane would break the sweep if plane moves and sweep is locked to a 3D edge.

Instead using 3D edges for the path, use pick lines and associate path with a work plane or a ref plane.

The profile moves arbitrarily when deleting original sketch line hosting it....that is normal! Or do you expect that the software predicts which sketch path to host profile to?... you can edit profile and repost that first to a specific sketch line then edit path and delete the segment u do not want

 This works fine when creating a sweep from scratch.

This is clear but I haven't found a way to select the hosting path segment.

This is exactly what I haven't found. How do you rehost the profile to a specific sketch line?

Well that is the limitation of Pick 3D edges...not a limitation but kinda the intent where Sweep Follow Edge. if you notice when you use pick 3D edges, you do not even have the option to lock...

To rehost profile planes, the profile need to be empty ...ie: none. that wont work if the profile was sketched too. It can be done only if the profile is loaded and I am not sure that is even supported in 2021. 

Your alternative in this case is to

When you edit the path, you can drag the profile plane to any segment you want. I believe @RDAOU showed this workflow on this forum a few years back.

@ToanDN i do not believe that works in his case...finish the sweep and try edit it and rehost...if u r using 2022 you should receive a message that the profile needs to be empty or something within this context

I'm on a train so I cant post a GIF

Yes I saw the same message.  There is a way around it by switching the profile back and forth between Named and By Sketch to empty it out so that I can move the plane, then assign or sketch the profile again.

That's why I told him he needs a loaded profile. . The sketched one cant be simply emptied

Ok, thanks to both of you (especially from ToanDN I have learned so much about Revit, so many thanks for all the time you invest).

I will check a little on the weekend and will then share my experience.

Have a happy weekend.

@ToanDN/ @RDAOU 

Ok, I've been playing around a bit.
First of all, in Revit 2019 one could edit the path by simply aligning it to another ref plane and honestly, in disabling this functionality in favour of "pick 3d line" I personally do not see the slightest improvement.
Secondly, as you've mentioned the problem at the moment is that i do not create a sweep but edit an existing one. Let's assume, a colleague has created it originally, let's assume it's a quite sophisticated door casing, let's assume the only thing that is wrong with it is that the path is aligned to the wrong base plane. I wouldn't want to dive into each alignment.
In my case what did work is:

- Edit profile -> Cut profile -> Draw some dummy profile -> Finish profile

- Edit path by picking 3D-lines (dont care where the profile plane goes) -> Finish path

- Edit profile -> Paste back profile from clipboard and move it to the right place -> Finish profile

- Finish sweep

However, as I've said in the beginning...

Thank you anyway.

There is not THE SOLUTION to the discussion I started but a workflow with contributions of @RDAOU as well as @ToanDN , so finding the best way for one self can be achieved by following the discussion.
