- [Instructor] It's critical to understand the modeling tree within CATIA v5. You'll notice that, with every file that you begin as a CAD part, you're going to have the three absolute planes, XY, YZ, ZX plane. Depending upon your settings, when you create your file, you can have an absolute axis system created, based off of those three planes. Here you can see these elements are all currently hidden. I know this, because the icon has a grayed-out or whited-out square around it.
This signifies that the element is in hide space. You'll also note, within the tree, I have a PartBody. This PartBody is a repository for all features based off of your solid modeling, sketches, features, everything will order themselves in timestamp in this body. You'll notice that I expanded the tree, by hitting the plus sign. Upon expansion, you'll see all of the features used to create the part. Now, the tree is nested in said fashion, where the sketch is the parent to the pad.
So, as you go through the tree, you'll see that Pad.1 has a parent, which is Sketch.1. Pad.3's parent is Pad.1 and so on. And each of these features is built off of the previous feature. Now, something that's of critical importance that you pay attention to is this little underline underneath the PartBody. This underline is telling you at which timestamp you're currently working. In this case, the PartBody is active, which means the entire PartBody is currently active, all features are there, active and seen.
There are times when you may want to change the current timestamp, so, if I come into, let's say, EdgeFillet.1 and right mouse click, by right mouse clicking, I bring up this menu. This menu has, as you can see, several options. One of the most important things is this Define In-Work Object. This is critical you understand. This Define In-Work Object allows you to modify the part, going through in a historical basis, meaning, when I define a work item on this fillet, I am going back in time to that exact moment that fillet was created and everything else below it is temporarily turned off.
Not deactivated. There's a difference. It is just temporarily turned off. This is my current in-work object, so anything and everything that I create will now be inserted at this point in time and afterward. It's important to know this, because as we go through the training material, we're going to be providing you a file, this file, that has all the features located in it. And, as we go through the training material, you're going to be required to turn on and off various features to whatever step corresponds to that exercise.
Now, as I go through, you can see, if I come to the Pocket.1, right mouse click, Define In-Work Object. I've just inserted that in-work object on the pocket, so if I choose to go in and create an additional feature, you'll note that additional feature now appears after that pocket. I'll select an edge and I will be talking about the EdgeFillet definition here shortly. But just to show you, now that I've created that additional feature, it goes in at that current timestamp.
Now, when I return to the bottom of the tree and I right mouse click over that last feature and say in-work object, that feature is now a part of that structure at this level. Okay, by clicking on it, you can see it. There it is. If I come back up and go to my Pocket.1 once again, Define In-Work Object, you'll notice that, even though the EdgeFillet is still there, it's not being seen because the in-work object is the feature before the EdgeFillet.
Other things to note within the tree are, if I come over to a feature, in this case, and move my mouse over the top of it, you'll see that the feature in the graphics window accordingly highlights, as well. I can right mouse click on that feature. I can say Reframe On. And it'll reframe on the part to the appropriate feature. So, if I come in and right mouse click over the Sketch.4 and say Hide/Show, I can now turn on the feature to be seen.
It is no longer in hide space. It is now in the show space. I can once again right mouse click and hide that. I also have the Hide/Show capability on a toolbar down below. In this case, we have Hide/Show here. Again, it's just a switch, on and off. What's important here is, right next to that, is the Swap visible space. By turning that on, I'm looking at what is now invisible. So, this gives me the ability to right mouse click over one of these features, as you can see, I can do it in the graphics window and it correspondingly highlights in the tree.
In this, I can now say Hide/Show. It puts the feature in to the hide side, so when I go back and swap visible space once again, you can now see the feature, as shown. So, if you're unsure where the feature's located at in the tree or the element is located at in the tree, you can always swap visible space, go looking for the part or the feature or the element, whatever it may be, and then Hide/Show to bring it back into visible space and then once you have the element selected in visible space, just swap back to your visible space.
And by navigating to the tree with these elements and within the part using the actual features, you can quickly find parts, elements, products, sketches, points, lines, planes. Other things to take note within the tree. I'll come up to the top. I'm going to go right mouse click. I'm going to say Define In-Work Object. By going to the very top body that contains these elements and saying in-work object, again, I'm turning on all of the features, so anything that I add will be added to the very bottom of the list.
I can also right mouse click, go into Properties. Under the Properties, you have the ability to go into Feature Properties and change the name. Let me type that in. I also have the ability to come in here and go into Graphic and specify the color of that element, in this case, the body is currently blue. I can change this, if I so choose to, and select Apply and you can see my cup holder now has that beige color.
I can change the Transparency, as well as, color of the edges. In this case, they're currently black. So, if I select OK on that, you can see I have my black edges, but if I can right mouse click on this once again, go into Properties, I can change the color of those edges. Say, blue. I can change the font, as well as, the thickness. And this is important, because, as we go through and adjust the attributes of the part, depending upon, again, where you work, you may have a specific requirement to show something in a color, meaning I may have a ribbon that needs to be trimmed off or I have a work edge or I have a tooling vector and everything has an associated color.
And this is how you would go in and adjust that color within the tree. Another thing that you need to pay attention to within the tree, once again, I'll just simply right mouse click, is you'll see I have the Cut, Copy, Paste, and Paste Special, as well as, if I go all the way to the bottom, you'll see what's called Reset Properties. If I select on Reset Properties and say apply to children, what's going to happen is all of the color properties that I've just applied in attributes will be reset to the default within the system.
And if I want to change that once again, just simply right mouse click, go into Properties, and adjust to the appropriate attributes.
