Draw Rules for Antitank Ditch and Wall

joebayles opened this issue · comments

From Esri/military-symbology#273

The point ordering for these two items is reversed, in both 2525C and 2525D.

Looking at the point order, some draw left to right, and others draw right to left, if the teeth are to be oriented the same way.

Code Name Direction
25290201 Antitank Ditch-Under Construction Right to Left
25290202 Antitank Ditch-Completed Right to Left
25290203 Antitank Ditch Reinforced with Antitank Mines Left to Right
25290204 Antitank Wall Left to Right

This issue also affects Obstacle Line (25290100), which is Right to Left.

FYI @ottenw, @wmcgrane, @mepler, @Twornicki

Concur with existence of this problem; will add to draw rules scrub / update I'm working on.

3 of 5 are drawn right to left, 2 of 5 are drawn left to right. My CP will change the 2 left to right so all 5 are drawn right to left.

Now that I am actively working on the change proposal to fix this issue, my initial thoughts on how to fix it may not be the best solution. All of the five obstacle lines listed in this issue share the identical draw rule Line1 in MIL-STD-2525D(1). In looking at these lines in the standard, I'm thinking they should have a draw rule and templates that have as much in common with wire and fence obstacles as possible. I'll have a working draft change proposal this week for the gentlemen listed in this issue.
