Mapping Commands from Old to New FLAC3D Syntax

This document lists commands from FLAC3D 5 (and earlier) and provides links to their FLAC3D 6 (and later) counterparts. Tip: using page search for the browser (Ctrl+F) can help locate a command quickly; the list below is extensive.

Table 19: User-Data Operations

FLAC3D 5.0

FLAC3D 6.0

LABEL arrow

data label create arrow

LABEL delete

data label delete

LABEL end

data label create end

LABEL text

data label create text

LABEL x y z

data label create position

the first four above optionally take an index with the “id” keyword (i.e., LABEL id 1 arrow),

in which case the corresponding translation is
data label create name "1" arrow,
where the index is now a string (that may be a numeral)

SCALAR add

data scalar create

TENSOR add

data tensor create

VECTOR add

data vector create

for the three above, the “import”, “export”, and “remove” keywords will follow the same pattern as “add”

with comparable translations (e.g., “SCALAR remove” will be data scalar delete), though note that “remove” becomes “delete” in 6.0 as seen in this example (“import” and “export” are used in both 5.0 and 6.0 syntax)
