Central heating flow and return line types?

Hi

Does anyone know if there is a standard or commonly used linetype for the flow and return feeds in a radiator circuit?

Thanks

Copy your acadiso.lin file and add this to the end. Load the file and you should have a linetype similar to below.

*FLDIR,Flow Direction ---->-------->-------->-------->----
A,.5,[ZIG,ltypeshp.shx,S=.05,R=270,X=-.05,Y=.05],-.0625,0,-.0625,0,-.0625,0,-.0625
*FLDIR2,Flow Direction (.5X) ---->---->---->---->---->---
A,.25,[ZIG,ltypeshp.shx,S=.05,R=270,X=-.05,Y=.05],-.0313,0,-.0313,0,-.0313,0,-.0313
*FLDIRX2,Flow Direction (2x)-------->---------------->--------
A,1,[ZIG,ltypeshp.shx,S=.05,R=270,X=-.05,Y=.05],-.125,0,-.125,0,-.125,0,-.125
