I recently viewed the class 45 Autodesk® Revit® Tips in 45 Minutes (Smith, Chad) on AU Virtual. It was an excellent class. Here are two things that I learnt:
You can Tab BETWEEN elements – in other words, select one wall in a chain of walls, then highlight another wall in the chain and press Tab. Only those walls in-between the two will be selected!
Pre-select when Filtering – before making a Filter, select an element first. Then go View – Filters – click on the ‘New Filter’ icon. The Category of the element that you select is automatically pre-selected for the new Filter!
