Zooming, panning, and regenning

Video: Zooming, panning, and regenning

AutoCAD drawings come in all sizes. We can work on everything from a small mechanical part to an entire college canvas. So it's important to know how to navigate your way around inside a file. In this lesson, we're going to learn how to use Pan and Zoom to adjust our view. On my screen, I've got an architectural example. This is a drawing of a floor plan for a single family home. Now, the trick to zooming and panning your drawing involves using the Scroll Wheel on your mouse. As an example, if I roll my Wheel forward, I can zoom in on my drawing. If I roll my Wheel back, I can zoom out.

Zooming, panning, and regenning

AutoCAD drawings come in all sizes. We can work on everything from a small mechanical part to an entire college canvas. So it's important to know how to navigate your way around inside a file. In this lesson, we're going to learn how to use Pan and Zoom to adjust our view. On my screen, I've got an architectural example. This is a drawing of a floor plan for a single family home. Now, the trick to zooming and panning your drawing involves using the Scroll Wheel on your mouse. As an example, if I roll my Wheel forward, I can zoom in on my drawing. If I roll my Wheel back, I can zoom out.

Notice that my zooming is focused on the location of my Cursor. So if I wanted to zoom in on the Master Bath area, I could place my Cursor over here and roll my Wheel forward to zoom in. We can also use the Scroll Wheel to pan. If I click-and-hold the Wheel down, remember your Scroll Wheel is also a button. I can drag my Cursor and adjust my view on screen. I'm going to release the Wheel, I'll come over here and I'll click-and-hold the Wheel down again, and I'll pan the drawing over and we'll center this car on screen.

Panning your AutoCAD drawing is a lot like panning in Adobe Acrobat document. Now, what if you're working on a Laptop or a Netbook and you're not using a Wheel Mouse? If that's the case, you can use the Pan and Zoom tools over here on the Navigation Bar. Using these icons, we can launch Pan and Zoom and the commands will run using out left mouse button. I'm going to pan the drawing over to the Kitchen area, and then I'm going to zoom in on the island and we'll center this on screen. Notice on the island, we've got an architectural drawing, I'm going to zoom in a little bit closer.

And as you can see, this is a drawing of the same floor plan that we're working in. Let's continue zooming in on this bedroom. I'll get a little bit closer and we'll center this on screen. Notice that even though I've zoomed in a pretty good distance, my geometry doesn't look pixelated, like what you would typically see in a photo editing program. That's because AutoCAD drawings aren't based on pixels, they are based on vectors. AutoCAD is a vector-based application, that means that all the line work that we see is based on mathematical computations. So I can zoom in as much as I want on this drawing and the line work is always going to look great.

That being said, let me back up a little bit. We'll pan over to the Bathroom area. Take a look at this toilet symbol. This guy is supposed to appear round, right now, it's looking a little bit angular. Since AutoCAD is a vector-based program, if we pan and zoom great distances, it can be taxing on the computer processor and video card. So what AutoCAD will do is it will sacrifice the quality of the arcs to allow us to pan and zoom freely on screen. Now, don't worry, this geometry will always plot just fine. However, its appearance may tend to break down from time-to-time.

If you'd like to clean up the appearance of the arcs, you can use the command called the Regen. And I'm afraid Regen is not available on the Ribbon, we have to launch this command from the command Line. So I'm going to click to place my Cursor down here and I'll type regen and hit Enter. And when I do, AutoCAD regenerates the database, it refreshes the geometry and I see a better representation of my line-work. Let's start zooming out. I'm going to roll my Wheel back, continue rolling back. Let's center this drawing on screen, I'll zoom out some more.

Take a look at the lower left corner of my screen. Even though I'm rolling my Wheel, AutoCAD is saying Already zoomed out as far as possible. I'm going to try pan. I'll hold the Wheel down, I'll try and pan this drawing over. Take a look at this, it's kind of like I'm panning into a brick wall, AutoCAD is not letting me to pan any further. This is another Regen issue. Remember that panning and zooming is taxing on your processor and video card. And if you've panned or zoomed a large distance, AutoCAD may ask you to regenerate the drawing before it allows you to pan or zoom further.

So let's launch Regen again. Here's a shortcut, we don't have to type the whole command. I'm just going to type re and hit Enter. When I do, I can now pan just fine and I can zoom as much as I like. Let's look at one more thing. I'm going to focus our attention on the Laundry Room area. If the time comes where you'd like to see the extents of your drawing, one quick way to get there is by double-clicking your Mouse Wheel. If I double-click the Wheel, AutoCAD will do a Zoom Extents and show me the visual limits of all of the geometry in my drawing.

Using Pan and Zoom, we can quickly move around in our drawing environment, no matter how large or small that environment may be.
