Symbol Library Annotation

In Draft, symbol templates are stored in Symbol Library (SYLB) elements. Each SYLB is like a drawing sheet containing pictures of all the symbol templates in the library.

In order to add annotation to the symbol templates it is necessary to create a Backing Sheet (BACK) element in Draft which is used as a backdrop on the symbol library sheet.

The annotation should be on layers separate from the symbol template graphics in the symbol blocks. This enables you to freeze the layer(s) containing the symbol template graphics and create a backing sheet from the remaining annotation layer(s) using the AutoDRAFT Frame Editor.

In Draft, you must add a reference to the backing sheet from the SYLB element (BSRF attribute) to see the symbol templates and annotation together.
