    callout questions

    I am transitioning from Autocad to Revit. I've been round and round through the "help" menus like it's Groundhog Day, but still don't understand the difference between building section, wall section, and detail callouts.

    I've attached a plan view showing detail callouts I draw all the time in Autocad. I can't figure out if these are possible in Revit:
    1) Descriptive text of what a callout is detailing, as an instance parameter within the callout head family.
    1a) I think I can modify a callout tail to approximate the arrow head. Yes?
    2) Callout leader with two or more segments.

    Are these possible? If so, any direction on how to create is appreciated. Sorry about any mistakes in naming the parts of the call outs (another thing I'm confused about).

    There isn't really much difference between them - they're "typicals" setup in the standard template to help a modeller differentiate, filter and organise views of certain scales used for certain applications. You can expand on them by creating new types, (just like you can elevations) so that you have different graphic-styles for the callout heads for your views, and can globally set view-templates faster. You may be happy with the single type, but certainly we have section & elevation head "styles" for site/building/detail - and callout "styles" buildings/rooms/details.

    The callout "region" (the area you sketch to create the view) can't (IIRC) be changed to an arrow-only, as it (in the first) defines the view extent of the new view (callout) you're creating. As for the addition of notes to the callout "head", as in your example, I've never tried, but imagine it might as simple as adding an instance-based text-field for the callout head family (you'd have to check) - but the disadvantage there (in documentation sense) is that you'd have to manage the text-note manually, rather than rely on the automated callout-view-referencing functionality that "points" the person looking at the drawing to the relevant view/sheet where the note (IMHO) would be better placed.

      Thank you for some ideas to chew on! I'll investigate further.

        If I'm reading your drawing correctly you can't do either of the two (or rather you can do one of them but I don't think you'll want to).

        The callout on the right has a 90 degree angle to the section it's cutting. You can't do that in Revit. The callout head will have to be in the same line as the section it's cutting.

        The callout on the left can't be done as shown since you need a rectangluar callout to link to the callout head. I suppose you might be able to do this by making the callout bubble small and hiding it under the callout head and adding a leader manually but then the callout won't be referencing model geometery.

        Lastly, the note you have next to the callout head I'd do with text rather than as a parameter of the callout. While technically you could do it with parameters the reality of it is you'd need a new callout head type for each unique note and your default browser organization would suffer as a result.

          I know it's not correct Revit procedure, but I'll reference a callout to a drafting view (where I drew my detail). The callout has the circular dashed area, but it's as tiny as you can get it so it just looks like a leader. I don't have an arrow, though.

            We do this all the time as well.

              Here in my office we use this method.
              We simply cover the callout bubble with a rebar DC.
              The text is set to transparent to let us see the line under.

              Hope this helps

                Here is a arrow family. Its a Gen Anno family and before you place you must add one arrow in the optiopns bar directly under the ribbon.


                We use the callout as well and shrink the boundry box down as small as we can. It can become tricky to select the callout after placement though.

                  Alexandre-

                  Your attachment looks a lot like what I'd like to do. Sorry for being dense, but what is a rebar detail component? I searched for one without success.

                    Alex-

                    Thanks for the family and example. After watching how you go about creating this, it does seem like a wishlist item. It's a small thing, but why oh why isn't it built in?

                    In your example, your leader looks like a single line; my leader is a boundary box that, while creating in a detail view, I can't shrink to less than about 1/16" square on paper. Are you just clicking quickly to make a tiny box? What kind of callout are you creating?

                    I'm still lost about the types. Somewhere along the way I purged my project and am no longer sure of my options. I think the main options are to add a reference to a perpendicular (section) or parallel (callout) view, then wither of these can be duplicated further as necessary for browser organization and graphics, per snowyweston above. Is this right?
