Drawing structure entities have names of the form A3DDrawingEntityName, for example `A3DDrawingModel`.

Drawing structures are divided into 2 parts:

- structure entities (`A3DDrawingModel`, `A3DDrawingSheet`, `A3DDrawingView`, `A3DDrawingBlock`)
- graphic entities (`A3DDrawingEntity`)

The root drawing entity is `A3DDrawingModel`which is a set of `A3DDrawingSheet`.
