The outofthebox system family anno_view_title has 4 types for title / without line / without detail ref / det ref with line etc but no option to zap the scale other than no title.
What if you want the title and no scale ( say for an inserted image dragged in from a drafting view )?
In Project Browser > Families > Anno_View_Title I edited (RC>Edit) and saved this as Anno_View_Title_custom. To show changes I changed the scale tag to a "phase" tag just to track the changes on project sheets. Load this into the project.
Titles 1 and 2 before
