Basic Technical Standards

The release of new national versions, the growing GRAPHISOFT®
product line and the BIMcomponents® portal
have dramatically increased the demand for GDL objects and object libraries.
As a result, many independent or third party GDL programmers have started
developing libraries or objects for GRAPHISOFT.

Basic guidelines are necessary to keep these objects compatible and
to achieve the standard of quality people expect from GRAPHISOFT products.
The purpose of this document is to provide guidance to GDL developers in creating objects,
with useful tips and tricks, examples,
descriptions of previously undocumented and new features.
