With Konstru you can upload a selection of elements or a group only instead of the entire model. Simply check the checkbox "Upload selection of elements" when entering the version description on upload. After clicking update Konstru you'll be prompted to select Active Selection or any available group from your model. Keep in mind that our Revit plugin will list Element Selection Filters instead of groups. While our CSI plugins are using groups. Select the group or active selection and continue your upload as usual.
