If you can make it through this mess!

Can someone please help me with this one!! I added a lot of script below to help provide my point. Anyway every one of these rafters is working correctly except for 9”ø. Maybe I have fat finger somewhere along the way, but I can not find it. But the very very very weird thing is that I can replace B = 0’-9” and H = 0’-9” with 8”, 8 7/8”, 10”, etc…… and leaving HLH_Rafter_Code still equaling as it was a 9”ø and it worked perfectly!! It’s only messing up when 0’-9” is placed at B and H.

After messing with it a little longer I figured out the problem is with B. I can make H equal anything and leave B at 9” and it doesn’t work, but to get it to work I tried a greater than less than statement B > 8 15/16" and B < 9 1/16" and it works great!! Once again it maybe a simple mistake somewhere, but for the life of me I can not find it.

You don't indicate how B and H are determined so it is impossible to say why that IF condition in not working. I suggest using a string type parameter with a values list to pick your rafter type so that the statement can read, for example:

IF rafter_type = "4x6" THEN

Conditions based on exact real number values can be tricky. It seems they can be undone by internal rounding errors. I have always tried to use greater than and less than to keep these reliable. For example, if I need to trap for 90 degrees (to avoid a divide by zero or some such) I would use:

IF angle > 89.99 & angle < 90.01 THEN

I started doing this when I found library parts which had worked in previous versions started to break in the new version of ArchiCAD at the time (AC6.0 if I recall correctly). I assume that it had to do with internal changes in the code or ways of handling precision and rounding errors. I also remember noticing that elements rotated or mirrored with the shift constrain would end up at 359.9997 degrees rather than zero.

Well this object is from good ol 6.5.
