LEVELOFDETAIL

Detaillevelsdeterminewhichpiecesoffamilygeometrydisplayindifferenttypesofprojectviews.WhenaRevit

elementiscreatedwithafamilyandaddedtoaprojectview,thecurrentdetailleveloftheview(coarse,medium,

orfine)displaystheappropriatefamilygeometry.

INTENT:Theintentistobuildthefamilybasedontheexpectedfinerepresentation,thenremovedetailtocreate

thelowerlevelsofdetail.Thisapproachimprovestheperformanceofthefamilyinlowerlevelsofdetailviewsin

theproject,butstillprovidestherequiredgraphicsforproperdocumentationofaproject.Theintentisnotto

buildeachlevelofdetailincrementallyoradditionally.

Familiesthatincludeintricatelevelsofdetailcanimpedeperformancewhenusedinprojects.Foroptimalfamily

performance,onlythenecessaryfamilygeometryshouldbemodeledandtheuseofhighlydetailed

representationslimited.

Whendecidingwhatlevelofdetailshouldbeshown,usethefollowingrecommendations:

• Don’tmodelgeometrythatwillnotbevisiblewhenthefamilyisaddedtoabuildingmodel.

Forexample,foratablefamilythatincludesadrawer,modelthefaceonly,nottheentiredrawer.



• Dependingonthetypeoffamily,usethefollowingguidelinewhenmodelinggeometry:

Ifthegeometryis… Setthedetaillevelto…

Smallerthan1’ Fine

• Donotduplicategeometrythatcanbeusedfordifferentlevelsofdetail.
