Issue:
In Fabrication CADmep 2026, the LFILL (Line Fill) command intermittently applies insulation to newly created parts even when the active service has no insulation specification assigned. This occurs despite the service database being confirmed clean and does not affect parts placed manually or via other routing methods. The issue appears isolated to LFILL behavior and is reproducible within the same session. Observations include:
LFILL-created parts showing insulation when Service Insulation Spec = None
The issue occurring after switching from an insulated service to a non-insulated service
Insulation persisting at the part-instance level even after reapplying the service
Manual part placement not exhibiting this behavior
Insulation only clearing if manually removed or if the service insulation is temporarily toggled on and off
This means every pipe that incorrectly assign insulation requires manual cleanup via Item Properties.
To reproduce this issue:
Open CADmep
Draw pipe with a service that has insulation assigned to it
Switch to a non-insulated service
Run LFILL
Insulation appears on non-insulated service
After discussing possible causes/workarounds with ChatGPT, it told me this: (Not sure if it helps, or is even accurate)
- LFILL appears to reuse previously initialized part data or cached part state and does not fully re-evaluate or clear insulation metadata based on the active service at the time of part creation.
