NOTE The convention for denoting the type of IGES entity is the numerical

construction type:form. For example, 214:2 is the IGES entity number 214, form

2. Form numbers can also be signed (given a positive or negative value).

Notes

When 3ds Max exports IGES, it supports name and color mappings to IGES

names and colors.

Since IGES requires unique names per element, 3ds Max will append a unique

identifier to multiple objects with the same name.
