I am attaching an image of error happening with me quite frequently. I am also attaching DXF of this parts which shows extra lines. That makes sense because those floating dimensions are not dangling.
Bend line dimensions are not updating automatically. Sometimes they float and lose their reference.
my process is "pack and go" the existing part, change the dimensions using design table and print the drawing. Then drawing goes to the shop floor. Sometimes I send drawing without checking.
For now, I am giving these dimensions manually in all drawing but I do want to use my standard process to reduce designing time.
