I was accustomed to the old issues where section fills would show OK in the model/scenes, but not necessarily in output animations, and back-saving to 2023 was the solution. However, the 2025 version seemed to resolve that. Now I’m using 2026, and I wonder if this new issue is due to the version, or if it’s a “me problem”.
The issue seems to be that a fill is there, but it has some opacity, and seems to be the lilac “back face“ colour, rather than black.
More than that, if the style is switched from “shaded with textures“, to “all the same“, shaded, etc., and even back to “shaded with textures“, then the section fill changes to the usual black, but isn’t retained with the scene. Hopefully the below video shows what I mean.
There are two scenes/sections, and section fill is ‘on’ and saved in both. There’s only one style, and section fill is ‘on‘ in it. Watch here as I switch the display style, which changes the “already on” section fill, from the lilac, slightly transparent type I mentioned, to the usual black. The display of the section fill reverts though on updating the scene tab and/or updating the style.
Looks like it is related to sketchy styles and the new graphics engine.I don’t see the issue with normal, non-sketchy edges nor with the Classic graphics engine selected. This is with the classic graphics engine.
Hopefully this bug will be fixed soon but in the meantime you could use TIGs SectionCutFace extension to create real faces ath the section cut. That will work with the new graphics engine and sketchy styles. You can also apply textures to the section cut faces and use the PBR materials.
No, I didn’t realise the axes were flipped, and I won’t have access to SU for nearly 24 hrs; do you know if that’s a factor in the issue… also the origin’s miles from the object, which is also odd.
No. It’s not related to the issue. If you didn’t move the axes for this model you should check the template you are using. Fix it if you need to and save as a new template. Also, turn off Length Snapping for your template. That gets in the way of accurate modeling.
I’m not sure where you had the axes when you made the geometry but resetting the axes places their intersection on the origin. It’s a little more than eight and a half meters away. You should keep the model close to the origin but it’s also not related to the section fill thing.
Predominantly resi architecture at concept/sketch stage. Typically a walkthrough with flyby/orbit, then introducing section cuts to show each floor plan and maybe a section, e.g. for vaulted ceilings.
