In this video, author Shaun Bryant demonstrates how to create isometric drawings in AutoCAD.
- [Instructor] We're staying in our Draw with Accuracy chapter, but we've got a new drawing for you. It's called Draw with Accuracy_Isometric. You can download it from the website and use it as the exercise file for this particular video. As the name of the drawing states, we're looking at isometric and what they call Isodraft functionality of AutoCAD where you can create isometric drawings that give a representation of a 3D object even though they are a 2D drawing. What you can do is you can specify where your isoplane is whether it's to the side, looking from the top, and so on.
How do we do that? Well it's in your status bar settings, but before we do that just make sure in your layers panel, you're set to the object layer as you can see at the top of the screen there. You just use the layer drop down. Just make sure you're using the layer object like so. Now in order to draw in this isodraft setting it needs to be switched on. It's down here on the status bar. It's this funny little sort of line crossover thing. If I click there that switches on, and it goes red and green. Can you see my crosshair changes? What it's doing now it's telling me that I'm in this isometric drafting setting.
What I can do is I can click on the arrow here, and I can set my isoplane to the left, to the top, or to the right. If I set it to the top at the moment like so and come into the drawing area, I can specify the top of my isometric view. This is really nice. I really like this because it allows me to draw quickly and accurately with the right angles, the 30 and the 60 degrees that I need to draw in an isometric fashion. I go to the Line command like so, and I come into the drawing area.
I'm going to pick a point roughly in the center of the screen, and as I drag, it gives me that 30 degree angle on the polar tracking. I want that line to be 10 long, so I type in a distance in the distance box, and I press Enter to finish. As you can see, it's drawn the line. I just press Enter again now to finish the Line command. I'm going to go back to the Line command now. I'm going to use this object snap here, and come up this way. Can you see it automatically gives me the angle, the 150 degree angle? I want this line to be seven long, and I press Enter again, and then Enter to finish the Line command.
Now the benefit I've got here is each of these lines, as I draw them, will be accurate. They will be that long and that isometric. What I can do is I just pan down a little bit there, and I'm now going to do the same again, Line command again. I come off of here like so. As I come out this way, I can type 10 again as the distance and Enter to finish like so. Then Enter to finish the Line command. Now I know that that is isometric, so what I can do now is just go line, and I can go endpoint to endpoint, and Enter to finish.
That's my isometric plan. You can see it's kind of rotated at an angle of 30 degrees. If I pan that upwards a little bit, what I can do now, is change my isoplane settings if I wish. I can come down here to the status bar, and perhaps I want isoplane left like so. If I do that now and I now go the Line command and click on this point here, can you see I can vertically draw a line there? Type in for enter. Then as I come off, it adopts the angle that I need. Can you see? It's just adopting the angle.
I can hover there and come vertically down and use things like object snap tracking. As I come up this way, I've got the angle again, so I can hover there. Come down this way, and it all snaps neatly at angles, so that I can now draw my isometric view. I've snapped to the endpoint there. Press Enter to finish. Draw one more little vertical line from endpoint to endpoint. Enter to finish, and there's my isometric view. With that isodrafting in the isoplane, it's very quick and easy to create a nice little isometric view in 2D that represents a 3D object.
Note: The exam objectives are not release specific, but the course has been revised to reflect the most recent version of the software, AutoCAD 2018.
