Unknown geometry showing up in analysis

mcauley-d14 — Fri, 28 Mar 2025 11:45:37 GMT

I have geometry showing in analysis (sun, daylight etc) that is not part of my proposal? I have everything turned on but I can only see these random geometries when I run analysis and so I can not find them to delete them. These random geometries are different in each proposal so I don't believe they are part of the base terrain, I have no idea what they are. Please help I am on a deadline

Hi!

This does not look correct, thanks for reporting. Is the geometry created inside Forma or are they imported?

Best regards, Vilde from the Forma team

Hi, thank you for replying. The geometry was created in forma using basic building and 3D sketch. I have used this in January and it was fine, so it is something I have done in the last few weeks

Hi @mcauley-d14,

Sorry for the issue! We might have introduced a bug in January that affected the creation of new 3D Sketch buildings which would cause this, but that bug has now been fixed.

As for the current element - which looks like it's actually several elements stacked on one another - you could try cut-and-pasting the data into a new 3D Sketch element (better to use just one element), then deleting the old in order to fix this:

Duplicate your proposal just in case
Edit the first existing piece in 3D Sketch by double-clicking
Ctrl/Cmd + A to select all, Ctrl/Cmd + X to cut
Exit, launch a new 3D Sketch from the toolbar
Ctrl/Cmd + Shift + V to paste-in-place - this is now your target 3D Sketch element
Exit the new one and cut the geometry from the next old element
Edit the new element and Ctrl/Cmd + Shift + V to paste-in-place
Eventually you'll have moved all the old piecemeal elements to the single new 3D Sketch element and you won't have this issue anymore
Optionally delete the old proposal if the new one looks good

This is only suggested since you have an existing 3D Sketch building that's in a bad state. New ones won't have this issue.

Let us know if this works?
