Curtain Walls and Other Elements

2.
Use the Design > Connect > Join Wall(s) to Curtain Wall… command, or the same command from the context menu.
The Join Wall(s) to Curtain Wall dialog box appears. Each time you join one or more walls to the selected Curtain Wall, use this dialog box to specify the exact connection point of the wall(s) to the Curtain Wall.
The Outside value: this defines the point at which walls coming from the “Outside” direction of the Curtain Wall will be joined to this Curtain Wall.
The Inside value: this defines the point at which walls coming from the “Inside” direction of the Curtain Wall will be joined to this Curtain Wall.
Both the Inside and Outside wall joining points are expressed as offsets from the Base Surface, as shown in the “Join Wall to Curtain Wall” dialog box.
The Default option is Curtain Wall thickness. This is likely to be your most frequent choice. By default, these Inside and Outside offset values total the Curtain Wall’s Nominal Thickness, as defined in Curtain Wall System Settings Geometry and Positioning Panel. In our example, the Nominal Thickness is set to 400.
If you want joining walls to stop at points other than at the Curtain Wall’s nominal thickness, then click Custom offset. Then enter values for the offset from the Curtain Wall’s Base Surface to the Outside and Inside wall connection points.
Click Join.
The eyeball cursor appears: click to define which end of the wall you want to join to the Curtain Wall. As you move the cursor to either end of the wall, a double-arrow appears on the wall, to indicate that this is the end that will be joined if you click now.
Adjacent Zones extend up to the Curtain Wall’s Nominal Thickness, as defined in the Nominal Thickness field of Curtain Wall System Settings (Geometry and Positioning Panel).
Use Design > Modify Curtain Wall > Split Curtain Wall, or the same command from the context menu.
Use the Design > Connect > Join Wall(s) to Curtain Wall command, or the same command from the context menu.
The Join Wall to Curtain Wall dialog box appears.
You may want a different geometry for this wall connection. Suppose you want the wall to join at the outside limit of the Curtain Wall. You must re-do the Join to Curtain Wall process.
Use the Design > Connect > Join Wall(s) to Curtain Wall command again to bring up the Join Wall to Curtain Wall dialog box, where you can adjust the connection offset to a custom value:
Since the wall is coming from the inside of the Curtain Wall, it is the Inside value which you will adjust:
The “Inside” value measures the distance between the wall connection point and the Base Surface, in the “inside” direction. If you want the wall to go past the Base Surface, as in this situation, enter a negative number. Here, we will use -50, so that the wall coming from the inside will cross the Base Surface (at 0) and keep going another 50 mm, stopping exactly at the Curtain Wall’s width thickness on the far side (the outside).
Click Join. View the result in 3D. Now the connecting wall is aligned with the outside face of the Curtain Wall.
