Quick Guide: how to do ballooning operations in QA-CAD/QA-CAD LT
• draw, delete and renumber balloons
• change balloon color and size.
• save Markup Edits
• publish a drawing to PDF
the drawing can be edited, deleted and balloons updated after saving if you always use 'Save Markup Edits' on the work drawing (you still have the original drawing which remains editable).
Only use 'Save As', or 'Publish to PDF' on the delivery drawing. These commands produce un-editable ballooned drawing file.
