Jeremiah,
I guess that's what I'm trying to say, the new drawing has no LK-* layers, the layer do not exist in the drawing, yet when i place a shrub or tree some of the LK-* layers line-weight and plot style do not change while other do, I'm only having issues with red, cyan, and 123.
I did a 2-minute screen recording, the first part of the recording shows that LK-* layers do not exist in the drawing by showing you the layers manager, the next part shows that the preferences for those block layers have been revised to what i need. The last part of the recording shows me placing shrubs, and the LK-* layers I'm having issues with being placed with their default line-weight and plot style (default, normal). I'm not sure how I get the recording to you since I can't upload as an attachment.
