UPDATE....
The new sheet is coming along well, I've removed the "Golden Numbers" enclosures. Along with the rectangular style custom enclosures like before it has design parameters for WEDGE shaped enclosures as well with customizable angles for the front to match up to any angle you want such as the back of your back seat. I have even added a TUBE enclosure for the person who occasionally builds them, I did it cuz it was easy to add and would make that particular calculation much faster. Right now I'm also adding a sheet with a box size calculator for those who have the BASIC theile/small parameters and are looking for a volume suggestion. Another addition is buttons at the top to make changing from the calculator's to the cut sheets a simple click and finally a HELP sheet at the end to hopefully answer some FAQ's when using the sheet. That's about it, lots of changes, some tighter calculations, and I'm trying to add more of the more common designs. If anyone has ANY suggestions for things they'd like to see in the program PLEASE let me know, it's impossible to build something to suit the majority needs if I don't know what the needs are.
