For several years I have been doing design work with the Excel Program alone as it is. I am in the Electrical Construction Business, I have made lay-out plans, wiring diagrams, block diagrams and even three dimensional detail structural type drawings. My
drawimgs have been submitted and reviewed by other Engineers which were left amazed by the design results since they all use Autocad. This has taken a lot of work of trial and error, inproving as I go.
My idea is that with a few changes to speed up the process Microsoft could have a new marketable product.
If interested I could send several samples of these drawings for your review.
