Of all the stuff I've done over the last couple years the Egress/Path of Travel family has to be the biggest hit. It has generated more email requests than anything else. I'm glad I've managed to do something useful!! If only I charged money for it! 8-)
So I'm writing to let anyone who has actually used it that there is a bug present in Revit right now that messes it up. The little dot and arrow at the end of the line-based segment won't print as filled in the latest build of Revit. If it doesn't work in earlier builds no one has said so and I can't test it on any earlier builds now either. Don't look back...keep moving forward...new build...well in this case it is a slight step backward.
The "fix" according to Revit Support staff is to print the views that these are used in using "Raster" instead of "Vector". Phew...that was close, I thought I was going to have to come up with a different strategy for those little guys.
Hopefully the bug will be fixed in a future build. For what it is worth, this most likely affects any nested annotation symbol that uses a filled region.
