' NX Journal: rebuild test master + diagnose why translator sees 0 solids (NX 2506)
|
|
'
|
|
' Hypothesis to test: UF CreateCyl1 built bodies that Part.Bodies counts (=2)
|
|
' but the STEP translator reports "0 solids". Suspect: unitless expressions
|
|
' ("bore=32" with no mm unit) produce degenerate/empty-shell bodies.
|
|
'
|
|
' This script:
|
|
' Phase 1 (single session, no reopen):
|
|
' OpenBaseDisplay -> ensure expressions WITH units (bore/stroke = mm) ->
|
|
' CreateCyl1 -> Update -> report body count AND face count per body ->
|
|
' add to MODEL refset -> export STEP (DisplayPart) -> Save ->
|
|
' export STEP again via ExistingPart (reads the saved file from disk).
|
|
' The face count tells us if bodies are real solids (cylinder ~3 faces)
|
|
' or empty shells (0 faces). The ExistingPart export tells us if the solids
|
|
' actually persisted to the .prt on disk.
|
|
'
|
|
' Run (run_journal takes one arg; use WorkingDirectory):
|
|
' WorkingDirectory = catalog-masters\KC (the .bat does "cd /d %~dp0")
|
|
' run_journal.exe <this file full path>
|
|
' Result log: <cwd>\rebuild-verify-master.txt Products: <cwd>\dbg_out\
|
|
'
|
|
' Note: English comments only (avoids GBK/BOM mojibake on no-BOM .vb files).
