Distance between two parts/assembly.

[gopinathmY575P]

Hello Community,

I'm looping through bom rows of an assembly environment.  i got output like below.

Level 4	Level 5	Level 6	Level 7	Level 8
Assly 1	Assly 2	Assly 3	Assly 4	Cylinder 1
Assly 1	Assly 2	Assly 5		Cylinder 2

i want distance between cylinder 1 and cylinder 2 based on its cg.

or if any other way, support with examples.

Hello @gopinathmY575P,

Knowing that the center of gravity of an occurrence is a point, we can use the distanceTo method to get the distance between the two points. Also, center of gravity of an occurrence is called Center of mass. Here an example that let's you pick two occurrences inside an assembly & calculate the distance between the two (default in cm) :

Dim occ1 As Inventor.ComponentOccurrence = ThisApplication.CommandManager.Pick(SelectionFilterEnum.kAssemblyOccurrenceFilter, "")
Dim occ2 As Inventor.ComponentOccurrence = ThisApplication.CommandManager.Pick(SelectionFilterEnum.kAssemblyOccurrenceFilter, "")

Dim cg1 As Point = occ1.MassProperties.CenterOfMass
Dim cg2 As Point = occ2.MassProperties.CenterOfMass

Dim distance As Double = cg1.DistanceTo(cg2) 'distance in cm!
MsgBox(distance)

Your question is not very precise, do you want to use the BOM to calculate ?

Kind regards,
