In this lesson, we will learn about alignment using reference planes. Open the file from the previous lesson or continue in the open file, Chapter Three, Phase One dot rvt. Open the elevation view south. Select the align tool from the tool bar. Select left side of the building for reference. Then carefully select the left edge of the wall and the imported elevation. Then select the lock toggle. Type ZF to zoom to fit. Now select ref plane from the basics tab of the design bar. The cursor will change to a pencil symbol. The status bar and tool tip will display information relative to the active command. Zoom in to the sectional part of the elevation file between column lines N and L. Pick the corner to the left of column N to start the reference plane. Then pull the cursor straight up so that the angle vector reads 90 degrees and pick a second point to create the reference plane. Now pick modify from the basics tab. Then pick the new reference plane and right click and pick properties from the context menu. In the element properties dialog, give the reference plane the name West Side of Walkway. And click OK. This plane will represent the exterior face of the upper story wall. Create a second vertical reference plane at the right edge of the section next to column line L. Name this plane East Side of Walkway. Use ZF to zoom to fit to see the model. Note in the building profile of the section that the first story is wider than the upper stories. Select each reference plane in turn and drag it's lower end below the model as you previously did with the levels. You are preparing to create the upper story walls that the section depicts. Double click on floor plans, second floor middle hall, in the project browser to open that view. Zoom in region around the key junction between the horizontal and vertical wings of the building. Note that the right-hand wall has aligned interior faced with the reference plane, not exterior face. Pick the align tool from the tool bar. Pick the right-hand east side of walkway reference plane, then pick the exterior right-hand face of the right wall. The wall will shift position. Toggle the lock symbol. This will fix the wall's exterior face to the reference plane. If you move the plane, the wall will move with it. Click the modify command in the basics tab to exit the align command. Revit Building's pyrometric capabilities allow the designer to establish a nearly unlimited set of relationships between building elements. We'll explore ways to take maximum advantage of these possible relationships in future lessons. The first, most pyrometric utilities is the alignment lock. When combined with reference planes, Revit Building's 3-D construction lines in a carefully planned design, locking and other orientation specifications can make even late design changes straightforward to manage. In the next lesson, you'll make changes to other walls. Save your file as this concludes this lesson.
