ilogic Rule To Change Units Of Measure

Issue:

Youve created some of your parts in inches and others in millimeters, but now youd like to convert them all to be the same. Is there a quick way to do this without having to open each file go to the Tools tab > Document Settings button > Unitstab?

Solution:

Heres an ilogic rule that can be run in an assembly or a part file that will set the units of measure. In this rule the length and mass units are being set. Set this up as an external iLogic rule to have it available for use in all of your model files.

You can use these links to learn more about creating iLogic rules:

------- start of ilogic ------

question = MessageBox.Show("Are you sure you want to change the units of measure?", _

"iLogic",MessageBoxButtons.YesNo)

if question = vbno then

Return

Else

get input from user

oUnit = InputRadioBox("Select a units of measure type", "Metric", "Imperial", True, "ilogic")

create precision value list

oPrecisionArray = new string(){0, 1, 2, 3, 4, 5}

get input from user

oPrecision = InputListBox("Select the number of decimal places to use for the units of length display.", _

oPrecisionArray, 3, "iLogic", "Decimal Places ")

example UnitsTypeEnum Enumerators

kCentimeterLengthUnits = 11268

kMillimeterLengthUnits = 11269

kInchLengthUnits = 11272

kKilogramMassUnits = 11283

kGramMassUnits = 11284

kLbMassMassUnits = 11286

If oUnit = True then

set to millimeter

oUOM_1 = 11269

set to kilogram

oUOM_2 = 11283

Else

set to inch

oUOM_1 = 11272

set to pounds mass

oUOM_2 = 11286

End if

Define the open document

Dim openDoc As Document

openDoc = ThisDoc.Document

set length units for the top level assembly
