First of all im not to sure if im positing this to the right forum and english is not my first language so bare with me.
So im having trouble getting the right formula for making a wand recess tag.
With a circle recess through the wall we just give it a tag at lets say 2750mm in the hart to make a hole in the wall.
But with a square recess we are having trouble getting our tag to work how we want it.
We are trying to tag the wall recess and point out the top part and bottom part of the air duct. so a air duct from 300 height would be / 2 + level to get the top part. But after trying for a few hours i'm not getting it to work.
i would say the formula is elevation from level 2750mm + height 300mm / 2 so top air duct recess is 2900mm on the tag.
Hope i have explained it properly, for any questions feel free to reply.
