Dan,
I downloaded your Roofslope_accessory.gsm and tried it out.
A couple of things.
If the roof pivot line is set at some arbitrary angle
your object rotates to that angle, as it should.
There is nothing in your script that I can see that
directs the arrow and text to rotate to the angle of the pivot line.
How does the object know this angle ?
I did notice that if one gives the roof pitch a negative value
or if you draw the roof with the pivot line at the ridge rather
than at the eave, the arrow does not change direction.
It still points down even though the the direction of the slope
is reversed. This is why I asked about which accessory parameter
defines direction. There are actually two "directions" if you will.
One is the angle of the pivot line relative to an orthogonal coordinate
system.
Two is the direction of slope up, down, relative to the roofs own
pivot line. The two "directions" can be combined to define a vector.
Thanks,
Peter Devlin
