Multimedia
The Multimedia branch holds image, video and audio annotations attached to a picked location on the model. Place one with Annotations → Multimedia, then choose the file; the object is drawn at that point and plays or opens when selected. Multimedia objects can be organised into folders like any other branch.
Their properties — file, placement, sizing and playback — are described under Annotations & Multimedia Properties.
Context menus
The branch header and its folders show the standard group menu, and each multimedia object shows the standard item menu. Both are listed on the Standard Item and Group Menus page.
