fair continuous sheerline

[mutt]

4.2.1 The sheerline shall be a fair continuous concave curve when view form side elevation.

[John m]

Why not would surely be a better question?

[mutt]

because it restricts avenues of invention.
'why not' is not a better question - surely there has to be a reason for our rules. We don't just write them for fun.

[THG]

Isn't this the rule that Radical Edward got around?  In view they are continuous curve in plan they are not??  Maybe wrong....
