Revit® Architecture Dependent Views and Revision Clouds

Another interesting Revit® Architecture discovery I made the other day while scrambling to get some revised drawings plotted in time to reissue them yesterday. The floor plans and reflected ceiling plans of this project are shown at 1/4" = 1'-0", and three separate drawing sheets are required to do so. (See this article for the key plan from that project.)

One of the long sides of the building has an array of typical patient rooms, and there was a change to the location of the light fixtures at the patient room entrance alcoves along that entire side, due to a conflict with ductwork. We have a ceiling plan view of the entire floor, and that view has three dependent views, each cropped to one of the three sectors. Annotation placed in the dependent view shows in the parent view, and vice versa, so I often work in the parent view, since that gives access to the entire floor.

I thought I would be "efficient" to put all of the revision clouds for the revised entrance alcove lighting in one revision cloud object. You can draw multiple, separate revision clouds in sketch mode in a single revision cloud object. So I drew them all in one object on one floor, added revision tags to each sub-cloud (you have to reclick the tag tool in the ribbon for each additional tag to be added to the same object) and then clipboard copied the object and tags and pasted it aligned to the other floor. I was so proud of how efficient I had been, until I checked one of the sheets and found that the revision clouds did not show up! Then I opened each of the dependent views and saw that the revision clouds were not visible there, either.

I double-checked to see that other revision clouds I had done as individual clouds did in fact show in both the parent and dependent views (they did) and was on the verge of getting disfunctionally frustrated when it occurred to me that perhaps the reason why the clouds were not showing in the dependent views was because one cloud object had graphics that were beyond the clip boundary of each dependent view. I made two additional copies of the cloud object on one of the floors - so that I would have one for each depenent view. Then I edited each of the copies, deleting all of the clouds that were not in the dependent view to be served by that copy. Once that was done, the clouds showed up in the dependent views and I was back in business, after adding tags to the two copies and then deleting the mega-cloud on the other floor and copying the three new clouds and tags to the other floor.

In hindsight, it makes sense that an annotation object that falls outside of the annotation crop boundary would not show up in a particular dependent view, but that did not occur to me when I started the clouding task. I will have to keep that in mind in the future.

I'm ecstatic to see such a detailed post over such fine minutiae. I last read your blog a couple years ago while working with ADT. I would read every word of every post, because this is the sort of insight that keeps the work progressing instead of stalling. Thank you very much, I plan to go through now and read every Revit post.

Thanks for the post. I was having this exact issue and your insight has provided resolution.
