Using iLogic to set component visiblitity based on Postional REpresentation

[NickRuberg]

Hi guys,

Can anyone suggest what code I would use in an assembly if I want to enable and make visible certain parts depending on the positional rep I am using.

Basically I am having trouble reading the pos rep into an iLogic code

Thanks,

Nick

I would probably abandon the pos-reps in their traditional Inventor form, and look at doing everything you want with your iLogic.  e.g If your pos-rep overrides an assembly constraint to move something, then your equivalent iLogic code would just set a new value for that constraint.  You can build from that simple example into amazingly complex assembly configurations using logic commands that make decisions about components based on your input.  (Yes - I'm a huge iLogic fan!)

Check our Curtis-the-iLogic-god's website for all the gold he shares with us mortals:

The visibility code is:

Component.Visible("PartA:1")

Which gets (or sets) the visibility of the part.

I should add this useful line:

Component.IsActive("Part1:1")

When you use this: Component.IsActive("Part1:1") = False

Not only makes "Part1:1" not visible, but it suppresses it also.  

The suppression is different from LOD suppression because you'll find the component is removed from the BOM too - which makes assembly configurations through iLogic all the more useful/powerful.

Hi,



I know that line and it is very useful, however my question is: how do I
read the pos rep in order to apply that line. What I want is the correct
iLogic syntax of:



If positional representation = raised, then

Component.isactive(... = false



If positional representation = lowered, then

..



So what is the correct way to query whether the pos rep is in position A (in
my case I call it raised) or position B or maybe position C



Thanks,

Nick

Hi NickRuberg,

Here's a quick example:

 'set a reference to the assembly component definition.
Dim oAsmCompDef As AssemblyComponentDefinition
oAsmCompDef = ThisApplication.ActiveDocument.ComponentDefinition

'record the active posistional representation name
Dim sActivePosRep as String
sActivePosRep = oAsmCompDef.RepresentationsManager.ActivePositionalRepresentation.Name

'Check the representation 
'and set visibility
If sActivePosRep = "Master" Then
Component.Visible("Part:1") = True
Component.Visible("Part:2") = True
ElseIf sActivePosRep = "Raised" Then
Component.Visible("Part:1") = False
Component.Visible("Part:2") = True
ElseIf sActivePosRep = "Lowered"
Component.Visible("Part:1") = True
Component.Visible("Part:2") = False
End If

'zoom all
ThisApplication.ActiveView.Fit

 I hope this helps.
Best of luck to you in all of your Inventor pursuits,
Curtis

Hi pcrawley,
Thanks for the kind words.
