Inventor - Surface area in assemblies

By Florentina Stirbu

When checking iProperties for the Area of an assembly, the value displayed is the sum of the areas of the parts it contains.

As this assembly has a portion of contact between 2 surfaces, it should be excluded from the surface Area value.

In order to view the “real” value, the following workaround can be used:

• Derive the assembly file into an .ipt - when deriving, make sure a single solid body is created!

• Check the iProperties of the Derived part – it now displays the value of the external area, excluding the portion where the surfaces are in contact with each other.
