OK, great. Update 1 did have a fix for this issue so thanks for confirming. 🙂

Also, can you send me a file that demonstrates the issue?

Hi @drock019, Are you using VW 2026 Update 1 or the initial release? If you're using the initial release, please get 2026 Update 1 when you get a chance and see if that fixes it.

TBH, I don’t remember if I knew what it was but it was handed over to another developer and I believe they know. Sadly, Velux doesn’t seem to see the value of continuing it. A real shame given how much effort went into the project.

As others have mentioned, this may be dangerous or illegal in some regions. But, surely decisions like that are up to the designer and the fact that stairs like this are allowed and exist tells me the software should allow it. I believe the Stair was implemented in such a way where simply allow users to enter "1" riser causes errors in the geometry. So, this isn't just a matter of us allowing it but this is a condition we want to address.

Right. The problem does look to be isolated to section viewports.

Hey @Christiaan, Can you file a bug for this so we can have a closer look?

Can you send me (via private message, if you prefer) a VW 2025 version of a file that has the issue in 2026?

As I mentioned, we're currently looking at better ways to address this. The solution in my video is a way to simply "hide" all wall lines below the cut plane for any wall or wall style until we have a better solution. Point taken.

Hi Thomas, This is a VERY high priority issue and will be addressed as soon as possible.

Hi @Amanda Priano, Thank you for sending the file. This issue is due to a new behavior in walls (in Vectorworks 2026) where walls not create a Top/Plan representation of themselves by sectioning their 3D geometry. This includes showing parts of the wall below but the parts below graphics are given the attributes of a chosen class. However, the below graphics are not actually placed in the class so you cannot turn off the visibility of that class to hide them. We're currently looking into a better way to handle this. Until then, if you wish to "hide" those graphics, you can choose a class that has a Fill and Pen of "None". See video: ScreenFlow.mp4

This is a known bug so please don't worry about reporting it.

Can you please post a simple file showing the problem?

This is a known issue (bug VB-197164). I commented on the bug report to see if we can get this bumped up in priority.

Hi @jason schneider, The changes in Vectorworks 2026 for these attributes was mainly to make them more flexible in the sense you didn't have to choose to set all attributes of parts directly, by object, or by class. You should be able to do things the way you did in previous version but it no longer locks you into using one of those methods for all parts. That said, we do want to look at how attributes for parts of objects can be better standardized between different types of objects and possibly be made more flexible.
