Vbapi - step csys

[braynpower]

Hello everyone,

Could anyone clear up how to modify my code below to select a particular CSYS for export? I started having a hack at it myself, but to no avail.... I've tried looking in the examples, scoured PTC community, gone through vbug.pdf etc etc etc, but cant make heads nor tails of it. I'm pretty sure my hamfisted approach is wrong on many counts. I have no VBA training, no programming knowledge to speak of, just a will to persevere.

The Step export works, so if anyone has an idea, it would be really helpful!

Dim GenMod As IpfcModel
Dim GenOwn As IpfcModelItemOwner '---------------------- This seems to be necessary, but as later mentioned, cant get 3dexport instructions to select or use the csys....

Set GenMod = session.CurrentModel

'Set GenOwn = GenMod '------------------ not sure this is useful, but I'm doing my best

'Set cSysS = GenOwn.GetItemByName(EpfcFeatureType.EpfcFEATTYPE_COORD_SYS, "STEPEX") '------------------meh, this doesnt throw an error, but I cant use it afterwards.... grrrr

Set cDesFlags = New CCpfcGeometryFlags
Set DesFlags = cDesFlags.Create
DesFlags.AsSolids = True


DesC = session.IsConfigurationSupported(EpfcExportType.EpfcEXPORT_STEP, EpfcAssemblyConfiguration.EpfcEXPORT_ASM_FLAT_FILE)

'Msgbox ("DesC = " & DesC)

DesG = session.IsGeometryRepSupported(EpfcExportType.EpfcEXPORT_STEP, DesFlags)

'Msgbox ("DesG = " & DesG)

Set cDesExStep = New CCpfcSTEP3DExportInstructions
Set DesExStep = cDesExStep.Create(EpfcAssemblyConfiguration.EpfcEXPORT_ASM_FLAT_FILE, DesFlags)
Set Des3DEx = DesExStep
Set DesEx = Des3DEx '----------------- I tried messing with the instructions .ReferenceSystem, but then it complains of an unset block or variable... I figure I cant be a million miles off... but some way for sure

GenMod.Export SATempDir & SAPName & ".STP", DesEx
