I'm sure this has been asked many times but none of the queries I used brought up a similar question. My issue is that I recently spent a lot of time annotating a detail view with leaders attached to geometry, leaders not attached to geometry, and sketches constrained to geometry projected from the view. I made some modifications to the model which didn't re-locate any of the components that I'd annotated, but somehow the detail view got shifted, and all of my leaders are pointing to the wrong place and the parts of my sketch that weren't constrained to geometry are in the wrong place as well. Some of the leaders seem to have held to ther posts better than others, but for the most part my annotations are worthless and will need to be re-done.
Has anyone else experienced this, and does anyone know of a way to prevent it in the future? Any suggestions are appreciated.
Solved! Go to Solution.
Did you have a drawing view selected when you crerated the sketch for the annotations? If not, the sketch is only for the sheet at large and will not travel with the view, nor respond to changes in geometry within the view.
For sketches created when a view is highlited, the view geometry becomes "projectable" and all sketched elements will move and update with the view. For annotations not touching projected geometry directly, I prefer to place a "sketch only" point that is dimensioned back to some relevant projected geometry so that any updates to the geometry will affect the otherwise unattached annotations. It's a bit of a pain setting it up, but less of a pain than repositioning all the annotations.
Thanks for the reply, jeanchile. Can you explain what you mean by having the detail view "attached"? I'm not sure I'm familiar with this.
No, I didn't know about the "perserve orphaned annotations" option, that might solve some issues--actaully thought I haven't noticed any issues of annotations disappearing, just moving to the wrong place. But thanks for the tip!

The blog post above shows the "attachment" of the detail views. This picture shows the two setting we adjusted to get results that were better:
We still have dimensions moving all over the place when we change something and we still have AD telling us that they have logged the issue, but we still continue to have problems. At least now when our models change, some of the dimensions stick around for us to re-attach.
I don't know exactly why my detail views moved in the first place so I can't test it, but it sounds like the detail attachment option is exactly what I need. That combined with the options jeanchile pointed out should save me a lot of drawing view headaches. Thanks for the tips!! Thanks also to graemev for the tip about constraining sketches with sketch-only geometry, that will be useful as well.
