Dear Sovelia Plant users.
An issue with isometric generation in Plant 2026 was brought to our attention. In isometric drawings the numeric material code gets rounded in the BOM. So the material "1.4307" becomes "1.43" etc.
After troubleshooting we could confirm that the problem was not caused by Sovelia Plan, but was present in Plant 3D v.2026 out of the box. We have been in contact with Autodesk, and they are aware of this issue. A solution is lined up and the fix will be implemented in the upcoming AutoCAD Plant 3D 2026 update. However, the release date for the update is not public yet.
The best workaround at this point is to add a space in the material code, for example "1. 4307", "1 .4307" or similar. Material codes with letters/spaces are not effected by this issue.
Thank you for informing us about issues so we can push for solutions from Autodesk.
