Wall Measurement Assistant Program

I'm looking for a tool that can help me with my wall measurements. This program should be both a spreadsheet and a diagram software. I will input the dimensions of my walls, and it should automatically calculate other necessary measurements and generate a list of materials needed to cover the walls.

- Ideal Skills: Proficiency in software development, experience with creating spreadsheet and diagram programs, and knowledge of wall covering materials.
- Experience: Previous work on similar projects will be highly regarded.
