Join Eric Wing for an in-depth discussion in this video Adding the cable tray, part of Creating Sprinkler and Fire-Alarm Systems with AutoCAD.
- Like anything else in AutoCAD MEP, Cable Tray is an automatic function. We can simply select the type and let AutoCAD MEP add all of our risers, drops, bends, and intersections for us. What I wanna do here is select a communications cable tray type from the tool palette. We'll then draw the cable tray from the electrical room up and over the wall, down the hallway, and bend it around the corner. Then we're gonna create an intersection and see what AutoCAD puts in as a default.
To get started, let's jump into our cable tray drawing, making sure that our workspace is set for Electrical. Let's go to the Cable Tray & Conduit tab. Let's go ahead and select Data. For the elevation, let's keep it at one foot. Notice we can change the width and the heighth however we want. I'm gonna click into my drawing area. I'm gonna come into my electrical room. I'm gonna pick a point right about here.
Now my elevation is gonna be 13.0' "This layout requires custom sized parts." Yeah, let's accept the layout. This time I'm coming out into the middle of my hallway. Notice that it reflects the same size that we had. I'm gonna go up the hallway, over the top of my conduit, I'm gonna pick a spot right about here. Now I'm gonna hit Escape.
Now what I'm gonna do is I'm gonna T into this and see what kind of intersection AutoCAD gives it. Select your cable tray, right-click, let's Add Selected. Shift + right click and let's go Nearest. I'm gonna pick a spot right about here. I'm gonna draw my cable tray out and over. I'm gonna pick a spot here. I'm gonna come straight up. Now I'm gonna hit Escape.
Again, notice, all of our bends are correct and it puts in our T-intersection for us. It arrays all of our lines down, we don't have to do any of that work. It even puts it on the right layer for us. Select this bend right here. Hold down your Shift key and your wheel button, let's go to a 3D view. Let's hit Escape. And here we have it. Right over the top of our conduit and comin' down the hallway.
Let's go back to our top-view. We can zoom in and see how well we can draw a cable tray. Again, sometimes the best results of 3D are efficiency in great-looking plans.
- Externally referencing architecture
- Setting up display configurations
- Adding room tags
- Setting up routing preferences and systems
- Adding piping and connectors
- Adding fire-alarm devices and control panels
