Creating Intelligent Details in Autodesk® Revit®

Creating the Detail )here are different ways to create details% Model everything and only notate the model" use the model as a place to start and then em#ellish #y adding detail items to the view" create standard details without any reference to the model It is unreasona#le to e&pect to model every element that needs to appear in details As an e&le it is difficult to model flashing and waterproofing" or welds and washers )his then necessitates the use of *D information in a set of construction documents )his session will cover how to use *D Detail Items to #est take advantage of their intelligence )hese principles apply to #oth drafting views and detail views

Detailing Best Practices If the detail is to #e *D yet still remain intelligent then a rule of thum# is to not use any lines or te&t in the detail" instead use detail items +formerly detail components, families" along with tags +either keynote or component tags, )his will accomplish a few things% it will allow for consistency in appearance" information" and spelling" while limiting lia#ility due to the incorrect information noted in a detail It is also a good rule to use a guide family to assist in alignments and the #oundary of the detail OOTB Detail Item Families A good starting place is with the Autodesk Revit out of the #o& families Autodesk Revit *-./ ships with 0-1 detail item families (ot everything needed will #e in there and more intelligence will likely need to #e added to some families" #ut it is a good start 2ne complaint a#out the 22)B detail item families is the line weights aren3t consistent with the office standards If this is the case each family doesn3t have to #e edited Instead the o#$ect styles can #e changed in the pro$ect +or pro$ect template," or view templates can #e created to accomplish the desired line weights If keynoting is utili4ed then all of the 22)B detail item families are aligned with the 22)B keynote file If element tagging is used" then these families will have to #e edited to include the desired information Despite the method chosen" a new keynote or detail item tag will pro#a#ly need to #e created since the 22)B ones might not match what is needed



Starting the Detail ie! 5ince this session will discuss *D details" the place to start is a Drafting 6iew A good practice is to create different view types for drafting views to help sort and keep track of details in the pro$ect 2nce the view is created" load a guide family Create the guide family from a generic annotation family 5o it will scale properly and provide a way to $udge the availa#le space for a detail )his family can #e set to adapt to different layouts and sheet si4es such that the correct drafting area is always accurate Reference planes can snap to the insertion point of the guide family which will then allow for snapping the view when placing it on a sheet +My sample guide family can #e downloaded from my #log post http%77#dmackeyconsultingcom7detailing8guide8grid7 ,



Creating the Detail 2nce the view has #een created" the graphics are all created #y placing detail items )hese detail items can #e anything from advanced families that are used on a daily #asis" to non8 parametric families that are used on a pro$ect specific #asis )he advantage of using intelligent detail items is the future capa#ility to tag these elements9 even simple elements that look like lines should #e a family for this reason 5ince there is a limitation on tagging repeating detail components" a single item will have to #e placed in a detail for tagging purposes" #ut repeating details can still #e used as well



Detail Item Families In order to compile a complete li#rary of detail items" creating new" custom content will #ecome necessary" the 22)B content will not cover every re;uired family )hinking a#out all the options that can #e added is a #ig step" and can seem daunting Considering line weights is usually one of the easiest places to start tili4ing a template will cause all the new families to #e consistent" and creating each family will #ecome less time consuming Revit doesn3t allow for the creation of family templates" however a family can #e renamed within windows e&plorer from rfa to rft 5o" create a family that includes the template information and then simply change the file e&tension )his process should #e used for #oth detail item and detail item line #ased family types +note% elements created in a template might not #e a#le to #e changed" for this reason keep the original rfa file in a separate folder for future changes,

Detail Items Line Base" ?ine #ased detail items also play an important role in detailing Most of the 22)B families such as gypsum #oard or structural framing are line #ased )hese types of detail items can play a large role in detailing @or e&le a line #ased concrete family could #e used as a wall" column" foundation" sla#" or #eam and this could a single family 5tructural re#ar" either in elevation or in section could also #e a line #ased family 2ne of the most useful detail items is simply a line" which can #e any line that needs to #e called out% #uilding wrap" vapor #arrier" lines of elements #eyond" etc a line family is virtually limitless Adding parameters to line #ased components adds another level of sophistication and adds to the fle&i#ility of the family )hese parameters an #e a range of items" such as visi#ility settings" angles or other dimensions



#mbe""ing Intelligence A #enefit of using detail items is the intelligence" automation" and efficiency they can add to details via tags Instead of manually entering it" information can #e em#edded into a family such that it can #e tagged once placed into a pro$ect )here are different ways this can #e approached all with advantages and disadvantages 2ne of the ways is to use Revit eynoting" a #enefit of which is anyone in the office can edit the eynotet&t data file without needing to have Revit installed 34eynote "anager from Re(olution Design is a must5! which can push information #ack into the pro$ect file without needing knowledge of Revit In addition rights can #e granted to only specific users in the company virtually locking down the tagga#le information for elements >nfortunately" the keynotes can only have two values for tagging" the keynote num#er and keynote description" therefore any element specific information needed has to #e added as te&t ne&t to the keynote 2ne nice part a#out this approach is a keynote legend +schedule, can #e created and then given to a spec writer" there#y limiting the time looking for all of the elements that have #een defined Another method is to em#ed information into parameters" +ie type comments, so that the intelligence can #e e&tracted and updated as the element changes


$este" Detail Items As more detail components are created" and as their comple&ity grows" nesting of other detail items #ecomes necessary (esting #ecomes vital if an array is to #e used" if notes or flags are to #e displayed" or simply it the swapping of one su#component for another is re;uried 2ne thing to take into consideration when nesting is tagging% if the nested element is going to #e tagged then it will have to #e shared In each family type" under the @amily Category and arameters" there is a check #o& for 5hared If this is selected the family can then #e tagged or scheduled +/D only, once it is loaded into another family >nfortunately if a family is marked to #e shared then type #ased parameters can3t #e mapped in the host )his means all parameters of a nest that are to #e mapped must #e instance #ased values (esting is also re;uired for family swapping" or changing one nested family type out for another >sing nesting for this purpose adds consistency" as well as fle&i#ility" into a family !owever" the draw#ack to this approach is that a user can change the value to any other shared family of the same type )his is why consistent family naming and understanding is a must +In the #elow image the fastener type for the door can #e changed to any nested shared detail item in the pro$ect,



Creating a Custom Tag Despite the chosen approach" keynoting or tagging" it is necessary to create a custom tag that will meets company standards )hat also is more fle&i#le than those availa#le 22)B 5o if the company standards include consistent left or right $ustified te&t" dictate the use of a #o& around the tag +or not," the need for a custom tag will #ecome inevita#le In addition as families get more advanced" multiple tags might #e re;uired to tag different shared parameters" rather than $ust tagging )ype Comments" etc )he 22)B keynote family only allows for the keynote num#er 2R the keynote te&t" not #oth together" plus" it is center $ustified 5o if the standard is to show the keynote num#er and te&t" and left $ustified" a custom tag will #e in order

)he 22)B detail item tag references the )ype Mark value is center $ustified" and can #e #o&ed or not >tili4ing a value other than )ype Mark might #e #eneficial to gain more fle&i#ility while tagging @or instance" a tag can use the )ype Comments and7or Comments to allow for consistency in the )ype Comments" #ut to also allow for fle&i#ility with individual notes #y using the instance #ased comments A tag can then #e set up to allow a user to change the tag type out if desired



Placing on Sheets )he last step in the detailing process is to place all of the detail files on a sheet A detail guide family that has #een added to the view will assist in the si4e and layout of the detail #ut unfortunately doesn3t help when placing it on a sheet )his is why reference planes are important


Conclusion )his session shared a method of detailing #y using only detail items" and #y not using lines and filled regions" therefore allowing the use of tags instead of te&t" and #ringing a level of intelligence to the *D side of Revit that is often limited to the /D side
