This is actually the classic way to develop Real DWG applications - work on the code inside Auto CAD, relying only on classes that are available in Real DWG, such as Database - and, once tested, build the code into a Real DWG application.Auto CAD is the perfect UI and test harness for Real DWG code.This suggestion came up in reference to this previous post about using side databases.
Optional steps: To open a properties dialog box where you can add or edit all the properties at once and view document information and statistics, click Publication Properties at the top of the page, and then click Advanced Properties.
On the Summary tab, you can add or edit the Title, Subject, Author, Manager, Company, Category, Keywords (also called Tags), and Comments. Custom properties are properties that you define for an Office document.
Using a predefined template, PROPULATE can fill in Drawing Properties data in folders of drawings.
The information that can be applied includes literal strings, attribute values extracted from specified attributed blocks and lists of attached xrefs, images and fonts.
You can assign a text, time, or numeric value to custom properties, and you can also assign them the values yes or no.
