Unlocking Wall Layers
As many of you know walls consist of several layers. These layers make up the total width of the wall assembly. The layers are made up of different materials assembled by you or whoever has constructed the walls you use. Often times we need to extend a portion of these walls without extending the entire wall. Luckily Revit allows you to do this. Here’s how:
Select the wall you wish to change. Right click and choose the Element Properties or simply select the Element Properties button on the Options Bar. Click the Edit/New button to open the Type Parameters. Then click the Edit button for the Structure parameter. This takes you to the Edit Assemblies dialog. Make sure you click the preview button located at the bottom left hand corner of the dialog. The preview shows you a plan or section view of the wall. Below th
e preview window click the view drop down window and choose Section: Modify Type from the list. In the Modify Vertical Structure (Section Preview Only) area located at the bottom of the dialog, select Modify. In the preview window zoom in on the top of the wall, and select the top Outer Boundary of the layer in which you want to move. Once selected a padlock will appear, click to unlock it. This will allow you to move that particular layer independently of all the others. Note: To achieve the desired look you must unlock all the layers you want to move. In this case I unlocked all the layers except the CMU to represent a furring wall that doesn’t extend all the way up. Your wall may be different. You may need to unlock the layers from the bottom for example. When you have unlocked all the layers needed to achieve the desired look click OK three times to exit the Element Properties dialog box to return to the project. Now when you select the wall in an elevation or 3D view you will notice an ex
tra Shape Handle (grip). This represents the layer or layers you unlocked in the Edit Assembly dialog. You can now pull it up or down independent of the other layers in the wall. Also if you go into the Element Properties under the Instance Parameters you’ll notice a parameter that was previously un-editable, (Top Extension Distance), is now editable. You can change the height of the unlocked layers from here as well. Go ahead, give it a try.
Welcome to revitED!
RevitED (Revit Education) and general BIM topics. I've been using Revit now for 11 years, and though I feel I've got a pretty good handle on the software it seems each day I learn something new. I want to share that with the readers of this blog and hope you learn something new as well.
