Description

MJW 99.10.28

The x-coordinate for Vertex 1 on a fin appears to be ignored, and the y-coordinate appears to adjust both the x & y positions of the fin origin.

See work around and solution...

MJW 99.11.10

With a fixed input (solar=+1, and schedules correct), verified that the fin placement for the simulation appeared to be working properly, just the dxf picture showed the fins in the wrong place.

revised 042-case620.idf checked in.

MJW 99.11.10
Indeed, it was just an error in the dxf picture, the thermal answers did not change. Fixed dxf checked in.

Workaround

This deck has a couple of problems. No Trans schedule is specified for the fins or overhangs. There is also no SCHX schedule which is used in Infiltration.

Fix

I believe the fins are now "fixed" for at least building north=0 and zone north=0. Need to implement the "north arrow" to help make sure others around the axis work equally well.
