I am working on drawing extraction since 6 month , I discovered that when you setup any rule then any modification on the model property the result will be disaster like ( the annotation will get back to its original place, disappear some times , duplicates ) any suggestion
...disappear sometimes? Sounds like mechanical annotation. If so, I recommend delaying initial annotation refresh/extraction as long as possible, because each time you hit that "refresh" button all rule-annos get reset to default. Also same thing if you enter the Drawing Model with "Enable Auto Anno" active; -So Mark's suggestion is very important. Too, when you modify straight duct/pipe in any way, all associated DG annotation and rule-based annotation is mostly forfeit. There are then, a bunch of halfass work-arounds that I use to get rule-annos extracted when additional mechanical components are added at a later time, or when revisions are made: Please test these first in a file where it doesn't matter: If you have to use the "Refresh" button where rule-annos already exist in a Drawing Model, then Select and "Group" all the annotations that you want to be unaffected, then hit Refresh. You'll need to then delete all the duplicates that are generated for the Grouped annos. The last step is to Drop the Group. The annos will then resume their associations (such as they are). Another I use for new straight duct/pipe that need elevation labels in a Drawing Model already populated with rule-base elevation labels: Label the new duct/pipe in the Drawing Model with the "size" DG anno cell. Go back to Design Model and stretch one end of the new duct/pipe and reconnect it exactly where it already was; Two things will happen in the Drawing Model, 1. The "size" DG anno cell will disappear, 2. The rule-based elevation labels will appear. If there's a lot to do, it's helpful to employ "Multi-Model Views".
