Q - question

iLogic: adjusting model parameters to match model volume or mass

A - answer You can use iLogic code to automatically adjust parameters of your Inventor model to yield a specific volume or mass of the model. You can use it in iteration loops without calculating the volume mathematically.

This is a concept - a sample code accessing and increasing the d1 parameter by 10% while checking the resulting Volume of the model (you can replace it with Mass):

ThisApplication.CommandManager.ControlDefinitions.Item("AppUpdateMassPropertiesCmd").Execute
myVolume = iProperties.Volume ' or Mass
MessageBox.Show("Volume before = " & myVolume, "iLogic")
d1 = Parameter("d1")
MessageBox.Show("d1 before = " & d1, "iLogic")
Parameter("d1")=d1 * 1.10
ThisDoc.Document.Rebuild()
d1 = Parameter("d1")
MessageBox.Show("d1 after = " & d1, "iLogic")
ThisApplication.CommandManager.ControlDefinitions.Item("AppUpdateMassPropertiesCmd").Execute
myVolume = iProperties.Volume ' or Mass
MessageBox.Show("Volume after = " & myVolume, "iLogic")
