square to round transformations.

[christopherfry]

I understand the normal format for airflow of a square to round is airflow from square to round (with this the offset data airflow arrow will be in the correct direction), i also understand that where airflow is in the opposite direction the only way to get the airflow in the correct direction is to change the in the options menu of the square to round, i.e. change inlet to 2 and outlet to 1, however by doing this the item geometry become incorect and the heights are taken from below the fitting not above and for example what is displayed as flat on left on the drawing becomes flat on right in the items data. Is there a fix for the airflow that doest mess up the manufacture data?

Hi Christopher,

To change the airflow direction you could edit the sevice and select extract or supply.

If i draw a run in supply, insert a sq-rd it will show the airflow in the correct direction.

if i then change the supply to an extract, the airflow doesnt change, it is always in the direction of sq to rd.

and yes flow dirrection in the service for supply and extract are set to supply and extract.
