Could you please clarify the extent to which a measurement tool may be used for a purpose other than what it is labeled for? I recognize that when creating this angle, you're not really measuring something. This preserves the spirit of using one measuring tool of each kind.
However, I want to ensure that corner case exploits cannot be extrapolated from the above wording / phrasing.
Laying a movement tool near the end of a range ruler while measuring range, then removing the range ruler but allowing the movement tool to remain on the board, effectively marking where the end of the range ruler was placed, could be seen as something other than it, "being used to measure movement". considered using that movement tool to measure movement. vs. "Being used to measure anything else". I understand the spirit of the idea but I'm concerned that people may try to exploit this by having more than one ruler on the table because it's "not being used to measure movement".
Are you able to offer further clarification for your ruling which may serve to preserve the spirit/intention of eliminating the simultaneous use of two tools of the same kind?
Thanks!
