PDM-IF IG Accomplishments 2016 Test round 1

• Active participation by 6 PLM vendors.

• Scope was: PDM-specific attributes, External

geometry, New versions of parts and document,

modification of geometry and placement, deletion of

element.

Test round 2

• Active participation by 6 PLM vendors.

• Extended scope compared to Round 1 was: Non-

CAD documents, Non-version changes, Lifecycle

state.

Test round 3

• Extended scope compared to Round 2 was: Explicit

configured product structure. Effectivities (Date,

STEP persistence in 3DEXPERIENCE

Ability to persist STEP files in 3DEXPERIENCE as alternate

representation of native part

Users can work in session either with the native parts or with the STEP Parts,

depending on their activity.

Design done with native Parts

Review, measurement, clash can be done directly with STEP Parts

Long Term Archiving taken into account since the design stage

STEP reference data can be checked all along the lifecycle

Archiving can be done easily (no geometrical conversion required)

STL (Stereolitography format)

Standards : 3 main formats for output to 3DPrinter

De facto standard & most often used today

Legacy format (1989), 3DSystem proprietary

Geometrical information only

Single object defined by a tessellation (list of

triangles)

AMF (Additive Manufacturing Format) 3MF (3D Manufacturing Format)

ISO standard (ASTM F42 / ISO TC26)

Emerging format (2013) extending capabilities

vs STL:

XML-based format

One or multiple objects

Support for color, textures, graded materials

Material for each volume - Materials can be

combined (graded materials)

Color for each volume, triangle or vertex

Constellations (Repeated instances)

Unit, formula

initiated by Microsoft and specified by the 3MF

consortium

Emerging format (2015), Open and royalty-free

specification from 3MFmembers

Similar capabilities as AMF offer (except formula) +

slicing description

Extensible, allow additional section to be added (new

extensions being prepared)
