How to switch everything in an assembly to metric

[chan67]

So I have a big assembly that is done in inches. 

I am now really fed up with it and want to change every single sub assembly and part file in it to mm and kg. 

How do I do that? I can change one part/sub assembly at a time from document settings, but I want to change everything at once. I have already set the default to mm and ISO but it didn't seem to make a difference. 

Thanks

If you want to do that all at once you might want to take a peak at iLogic.

The folks in Inventor customization might be able to help you start out 🙂

Have a look at that, especially message 10.

Hi, try to execute the following ilogic code at the main assembly level.
If it works, remove the asterisk in the line

'docFile.save
not what I removed before because if it does not work well, I would save the file with an error, for security I avoid saving the file in the codes until I am sure that they work as I want.

Dim oLengthUnits As String = 11269
Dim oMassUnits As String = 11283

Dim oDoc As Document= ThisDoc.Document
oDoc.UnitsOfMeasure.LengthUnits = oLengthUnits
oDoc.UnitsOfMeasure.MassUnits = oMassUnits

For Each docFile As Document In oDoc.AllReferencedDocuments	
	On Error Resume Next
	docFile.UnitsOfMeasure.LengthUnits = oLengthUnits
	docFile.UnitsOfMeasure.MassUnits = oMassUnits
	'docFile.Save
	docFile.Rebuild
Next




'---------LENGTH UNITS--------------
'kFootLengthUnits 11273 Foot Length
'kInchLengthUnits 11272 Inch Length
'kMillimeterLengthUnits 11269 Millimeter Length
'kCentimeterLengthUnits 11268 Centimeter Length
'kMeterLengthUnits 11270 Meter Length 
'kMicronLengthUnits 11271 Micron Length. 

'---------MASS UNITS---------------
'kLbMassMassUnits 11286 LbMass Mass
'kSlugMassUnits 11285 Slug Mass
'kGramMassUnits 11284 Gram Mass
'kKilogramMassUnits 11283 Kilogram Mass

 This rule will change the units of your assembly and all assembly reference files.
I hope this helps with your problem. Regards

Hello @chan67 !

Great to see you here on Inventor Forum.

One part (only one as far as I can tell) got deleted for some unknown reason and it broke my assembly. Other than that it seems to work fine. Maybe some problem with the loop? 

(don't worry I backed everything up)

No one knows. Without seeing the files.
