The Assembly Editor allows you to extend the BW Tools with your own pieces of clothing, props and things. Please use the menu commands Tools / Assembly Editor to start this tool.
In order to create a new item, you first have to create a textual file describing its properties, parts etc, the assembly file (stored with .asm extension). You can create this file with any text editor which is able to store a plain ASCII file and import it into the system. The easiest way, of course, is to use the integrated text editor of the Assembly Editor. This editor knows about the syntax of the BW Tools assembly language and helps you with coloring of the keywords.
The assembly can be compiled and interactively viewed by using the Refresh! menu command.
Use the File / Create or Create As... to create the final outfit or thing.
