I am working on a program that uses classes to draw components of PIPE and HVAC systems in Detail and arrangement forms. Current the program has some odd 120 classes, one for each componet that we have done in PIPE or HVAC i.e. a sleeve, valvue, tee, and so on. The program is getting to the point where it is hard to manage and update because of the number of classes. I have been assigned the job of finding a way to eliminate the mass number of classes and replace them with some type of outside file, like a DB or INI or even a txt file. It isn't possable to use a dll thats the first thing i tried .

So my question is does anyone know of a way to store equations outside of VB in a file and then run them inside of a VB program. The Idea is to gather all the need information then read the geometry equation from an outdide file that would be easy to update and manage via a second program....
