Voor de verspanende bewerkingen is het STEP formaat meestal de juiste weg. De AP203 standaard is de meest gebruikte.
Pakketten die draaien op de Parasolid kernel, zoals SolidWorks en SolidEdge, schrijven het beste uit in Parasolid(x_t). Ons CAD/CAM pakket(TopSolid) draait ook op deze kernel.
Pakketten die draaien op de ACIS kernel schrijven het beste uit in SAT formaat. Inlezen van SAT lukt echter niet altijd. Bij voorkeur dan in STEP.
IGES is de oudste standaard. Deze geeft echter vaak problemen omdat er nog al wat opties in te stellen zijn. Onderstaand een overzicht van het uitschrijven van IGES bestanden vanuit verschillende pakketten.
Solidworks IGES file exchange
SolidWorks Standard IGES export type uses analytic surfaces. To export models, use one of the other IGES types like SURFCAM or Mastercam that use NURBS surfaces.

Exporting From Mechanical Desktop
The best way to get geometry from Mechanical Desktop (MDT) release 2.0 into Rhino is to use the MDT IGESOUT command. To get the best results, you may need to adjust the MDT IGES export options.
To export:
5 In MDT start the IGESOUT command.
6 In the Autodesk IGES Translator R14 - IGESOUT dialog box, click Edit options.
7 In the IGESOUT Options Editor dialog box, click Start and Global.
8 In the IGESOUT Start and Global Options dialog box, set IGES Version to either 5.2 or 5.3.
Version 5.3 stores years as 4 digit numbers. Version 5.2 stores years as 2 digit numbers, and click OK.
9 In the IGESOUT Options Editor dialog box, click Structure.
10 In the IGESOUT Structure Options dialog box, set Map Layer Names to Level Property (406:3) and click OK.
11 In the IGESOUT Options Editor dialog box, click Geometry.
12 In the IGESOUT Geometry Options dialog box, set 3D Solid/Designer part mapping
to Surfaces, and set Trimmed Surface Mapping to Bounded surface (143) and click OK.
13 In the IGESOUT Options Editor dialog box, click DE Mappings.
14 In the IGESOUT DE Mapping Options dialog box, check Color Definition Entity (314) and click OK.
15 To save these settings, in the IGESOUT Options Editor dialog box, in the Description
box, type something like MDT to Rhino and click Save As. Save the options in a file called something like MDTtoRhino.opt.
Note
There are lots of MDT IGES options that are not mentioned in the discussion above. You may set these options as you see fit. (The MDT defaults work fine.)
