I've noticed in 2012 a problem with AutoCAD styles and feature lines. Here's what's happening.
I created a block ("Block1") with mtext (to style "Text1"), with dimensions (to style "Dim1" with font "Text1"), and with mleader (to style "Leader1" with closed heads and font "Text1").
I have created a marker style ("Marker1") that uses the block "Block1". I then have a feature line that I use to insert the marker "Marker1" into my profile.
The text style, dimension style, and mleader style that were in the block are the wrong style as displayed in the marker. If I insert the block into the drawing, the text style, dimension style, and mleader style are the right styles.
In the block, OK. In the marker, wrong.
I have 32 bit. My co-worker has the same problem using 64 bit. This only appears to appear when you are using the marker with a feature line, and the marker when inserted as a PI marker comes in correctly.
Does anyone else have this problem? Or am I on my own again?
