May I please offer suggestions for the first paragraph under Protocols? This is meant to be constructive rather than just critical.

The second sentence is confusing. The concept of projecting three dimensions onto two is already available from the first sentence of the introduction. The mention of scale is confusing. Unless multiple scales are specified, the reader should assume that a single consistent scale applies for the whole construction. What is meant by "an invisible (point view) axis receding ..."? This suggests perspective although that probably was not intended. What is meant by "... shares a full-scale view ..."? Each projection can be made independent of the others.

Rewriting the paragraph should be considered.

I agree. I added one of those templates used for that purposes. There actually a lot more things needing work than this sentence, I'm confused also by the diagrams at the end, and most of the info is given without telling the sources. --Allefant (talk) 16:12, 18 November 2007 (UTC)[reply]
