It is possible to have more than one user library (for plants as well), but project libraries are not so easy. Material and plant libraries work in very similar ways, and all of the following information applies to both.
The files that contain the material libraries are normally stored in the c:/accuren3/common/support folder with the name USER.MLIB. The plant library is called USER.PLIB. If you need to back up your libraries (which you should do on a VERY regular basis) these are the ones to copy.
To create a new library, use the library menu in the materials/plants dialog box, and choose new. When you type the name, you will notice the new, empty library appear in the list. You will also notice that the library file (.mlib or .plib) appears in the c:/accuren3/common/support folder. By default, AccuRender only looks in that folder for the libraries, but this can be changed. Use the options dialog in the tools menu. Change the drop down box from "General Search" to "Library Search" and enter the new path there. Press Add, and when you move the library into that folder, it will appear in the library list. Notice, though, that if you put the .mlib file into a subfolder, it will not be found. Subfolders must be specified one by one.
The "General Search" is also very useful. It allows you to place your bitmaps (for materials) into folders other than the one specified in the material definition. If the bitmap is not found, AccuRender will go looking for it in the "General Search" path. Subfolders are included, so theoretically you could just add "C: D: E: etc." This slows down the operation of AccuRender, though, so its best to point to specific directories.
AccuStudio uses this to good effect. When you download the material or plant libraries, they are unzipped into the c:/accustudio folder. The .mlib and .plib files are found in the folder itself, so "c:\accustudio" needs to be added to the "Library Search". We also have many subfolders within the c:\accustudio folder for the bitmaps that are used in the materials. As long as the "General Search" points to "c:\accustudio" it will find them all.
One common question is "Can I have different libraries for different projects. In AR3, this is not so easy because the program does not look in the drawing directory for the library by default. Consequently you either have to add each project directory to the search path manually, or have a special folder full of .mlib files called after each project.
