Hi msx80,
First of all I would like to say your blueprint and bluerender is super awesome! I register into eurobricks just because of this thread. The "use shade" option in blueprint really improve the visual impact to be much more visible especially for white colored bricks. I can now directly tell the brik's dimension without squinting so much .
Just an idea for a better visual cue, maybe you can add these:
1. a parameter to adjust the outline thickness (normal and bold maybe?)
2. an option to change the 'new part' pink high light to be another color or maybe you can make the "previously assembled part" to become semi transparent and the new part to be solid?
This is especially helpful when making instruction with a lot of pink bricks to work with.
Sayonara and arigato!
