AutoCAD is a computer-aided drafting and design program that is the industry standard for a wide variety of 2D and 3D work. AutoCAD 2008 features several improvements over previous versions, but the core functionality and workflows have remained consistent for years. Users who have any of the more recent editions of the software will find AutoCAD 2008 Essential Training to be a valuable resource. Instructor Jeff Bartels has taught and used AutoCAD for a decade, and in this course he focuses on the difficult to master concepts that matter most to professional AutoCAD users. Exercise files accompany the course.
grips are probably the most versatile tool in AutoCAD. We can use them to make quick revisions to our geometry. In fact, we can use grips to accomplish nearly every modification command, we have talked about so far. Let's take a look at how they work. I'm going to open a drawing such that we can play around with the grips feature, so I click my Open icon. I'm going to come down within the Chapter 9 folder and I'm going to select the number 8 drawing the MP3 player. Let me select this and click Open.
Now on my screen, I have got an MP3 player as well as some scrap geometry. One thing I noticed right off the bat is drawing opened up in a window, let's correct that I'm going to maximize my window, so it fills up my interface. Now to the right of my MP3 player, I have got some scrap geometry, we are going to use the scrap geometry to get the idea of how the grips feature works. First off, I'm going to click on this line to select it and when I do I can see these little blue squares, these are grips. grips act like little handles that I can use to modify my geometry.
Now the grips feature can actually be turned off, so if you can't see grips on your screen, let me show you where you can go to turn them on. I'm going to hit my Escape key to clear the grips and once again if you do not see grips, this is where you can go. You can go to your Tools pulldown, come down to Options. We are going to go to our Selection tab, let me click the Selection tab and write down here there is a checkbox that says Enable grips. If you can't see grips, that's where you go to turn them on. So I'm going to click OK to get out of the Options dialog.
As long as we are talking about settings, make sure that your Dynamic Input is set for this particular demonstration. The Dynamic Input or the Head's-Up Display gives us additional functionality with grips. Now I'm going to come up and click this line again and this time, I'm going to move my cursor on top of one of the end grips and I'm just going to hover, I'm not going to click. Notice the computer gives me the length of the line as well as the angle at which that line was drawn. Let me come down and click this arc and I will hover over this end grip.
Notice I get the angle of the end of the arc as well as the radius. Let me hover over this middle grip. I can see the radius and I can see the total angle of the arc. I'm going to come down and click my circle. Let me hover over one of these grips, I get the radius of the circle. So I can use the grips features to query my geometry. I'm going to hit my Escape key to clear the grips. Now let's make a geometric change using the grips feature. I'm going to come up and click this line, this time instead of hovering over the grip, I'm going to click on it.
When I click on the grip, the grip turns red. Notice that I have some fields pop up on my screen, I can use these to change my line work. Now if I hit my tab key I can jump through the various fields, there is actually four of them, that first one represented the amount of change that I want to make to my line, this one represents the total length of my line. If I hit tab again, I can see the angle of the line, hit tab again I get the amount of change, I want to make to my angle. So I'm going to hit my tab key and will tab until we get the total length of the line.
I'm going to type in 1 and hit Enter. I just made that line one unit long. Let's make a change to the arc. I'm going to click the arc and if I would like to have this Fields functionality I need to click on the triangular grip. Let me click on the triangle. Notice I get the same field. I get one that represents the radius, this guy has a radius of 1.49. Now let's make the radius 1.75 and I will hit Enter.
I just change the radius of that arc. Let me come down. We will click the circle. I'm going to move over this grip and click. I get a field representing my radius. If I hit tab, I get a field representing the amount of change I want to make to my radius. Let me tab until I get to the measurement that represents the full radius and I'm going to set this to a radius of 1. Let me type in 1 and hit Enter. That circle now has a radius of 1. Let me hit my Escape key once again to clear the grips.
Now as I mentioned earlier, we can use the grips features to do nearly every modification that we have seen so far. Let me show you what I mean. If I come up and click on this line I get my grips, I'm going to move over an end grip and click, that guy turns red, he is now hot. Take a look at the command line right now. The command line says I'm in the stretch mode that means if I move my cursor, I'm stretching this line based on that endpoint. Watch this if I right-click when that grip is hot, I have several other modifications I can make.
If I select move, I'm now moving this line based on that grip. If I right-click, I can select Rotate. I'm now rotating this line based on that grip. Let's go again, I can right-click, we can select Scale. I'm now scaling the line based on that grip. So we have several modifications, we can make just by using the grips feature. I'm going to hit Escape to cancel out and I will hit Escape again to clear the grips. Let's use the grips feature to make a change to our MP3 Player.
Let's say, I would like to change my screen size, I'm going to come over and click the screen and let's hove over this corner grip and find out what the dimensions of my screen are. If I hover over the corner, I can see that my screen dimensions are 2 x 1.6 inches. Let's say I would like to make a 2x2. Let me click the corner grip, I'm going to hit my tab key until I get to the overall length of the side. Let me change this to 2 and hit Enter.
Now notice the whole thing didn't change just that one grip changed. Let me come over and we will adjust this grip. Let me click and by default AutoCAD is grabbing the dimension that I want to change, so once again I'm going to type 2 for 2 inches and will hit Enter. I have just changed my screen to a 2x2 dimension. I want to make one more change, let me hit Escape to clear these grips because now that I have changed my screen my thumbwheel is kind of tripping over the edge.
Let's move the thumbwheel down, I am going to do that by using grips. I'm going to click in the upper left hand corner and will make a nice window selection around my thumbwheel. Let me click to finish the window. And I'm going to move up and will click the center grip. From this point I can right-click and select Move. I'm now moving this thumbwheel based on that grip location. Well, I would like to move this accurately so let's turn on our Ortho. Let me come down and click my Ortho button.
And now I'm at least moving this guy in a 90 degree locked angle increment. So I'm going to pull it in downward direction and I am going to type in a distance of 0.25 and hit Enter. I just moved him down a quarter of an inch. Let me hit Escape to clear the grips. Using grips can be one of the fastest ways to make changes to your geometry, in fact grips can do much more than what we have seen here. If you know how to use these little blue handles, you are well on your way to understanding future concepts like dynamic blocks and 3D modeling.
