getEffectiveNameFromBtrId helper works for AutoCAD, however BricsCAD doesn’t have a direct API to do this for parametric blocks, I’m investigating alternatives.
vla-get-effectivename, "EffectiveName~Native" are designed to give us the name from a block reference
blk = table.blockTableRecordId(cell.row, cell.column)
gives us a Block table record id, not a reference
I have a working solution with the help of Bricsys support that should give us what we need, it’s a bit of a kludge though
