An interesting development occurred with a client recently. They are using an old practice of having a base drawing with all the labels and associated data in that base drawing. This base drawing is then xref’d into the plot sheets.
The interesting development was when they had label styles where the dragged state arrowhead was set to none. In the base drawing the labels all looked correct with no arrowhead. Yet, when the drawing was referenced in the labels now had arrows!
Now here is where things get really interesting. When I go and change the current dimension style’s leader arrowhead to none, then we get the labels looking correctly again! This is the AutoCAD dimension style!
This is a confirmed issue but easy enough to correct. Just set the base drawing’s label style arrowhead SIZE to something like 0.00001.
Sometimes providing technical support can be an interesting adventure
