Join Henry Santos for an in-depth discussion in this video Deformation tools, part of MODO Essential Training.
- [Instructor] When working with 3D models, we sometimes need to deform the shapes. Now we could select the different components as we've seen in earlier videos, and move them or reshape them. But in MODO there are certain deformation tools that can help facilitate that process. So let's make sure that we have the right project open. So we go to File, choose Project, Exercise Files, ch_03.
Now let's Open a File, File Pull-down and Open. And there it is in our chapter three Scenes. Let's open up 03_07. Here we have three chairs, and let's go through how we would modify this. So as we've seen in earlier videos, we can change to our Polygon selection, or Edge, or Vertex selection. In this case, let's go with Polygon selection.
And I'm gonna select all of these here, these polygons, holding down the Shift key and selecting the different parts that I want to modify. Okay. Now we can move this, rotate it, move it again and we can come up with different shapes, so it's pretty, pretty cool how we can edit that.
But there are quicker ways to modify the shape, so let's Undo that, and I'm gonna Deselect all of the selections. Now if we look at our tool sets, we were using the basic tools earlier. Now let's move to the next group of tools. Right below that it says Def, if you wanna see the whole word, just drag that separator so that it will spell out the entire word, so we have Deform, and the very first one's called Element Move.
So Element Move will move each one of the elements that you select. So if we hover over a polygon, it will select the polygon, or if you hover over an edge, it will select that edge, and hover over Vertex, you can select the vertex, but let's see what we can do here to reshape this. Click on that Polygon, and just start dragging. And then the thing you notice is that the move controller is still active while we have Element Move selected.
We can select that. Now if we wanna move this edge, select that, and we can quickly reshape on the fly. We can just click and drag, when I'm hovering over that vertex at the very top in the center. I'm clicking and dragging. So very quickly, you can explore different shape options.
Move that down so we have a nice design. And there are other tools within this bank of tools that'll do similar things. Let's jump over to the next grouping of tools, so that we can get a, a good overview of the deformation tools. So I'm gonna go to my Item List, and select a Chair Bend. That's the next chair.
What we can do, is select the polygons, but I'm just holding down the Shift key now and clicking and dragging over all the polygons that I want to control or effect. I'm gonna Rotate my scene, hold down Shift. Click and drag over all of the polygons that I wanna select, and there you go, I wanna select all those guys.
And what I'll do is look at it from somewhat of a side view. And I'm gonna use the Bend tool. It's half way down that list of Deformation tools, underneath the Rotate tool. Select that. I'm gonna click in the scene, and now I'm gonna rotate it, but nothing really is happening because our spine is 60 meters, if we look at the lower left corner of our screen, one thing to make sure of is when you click on the screen, that all your settings are correct, so that's a little bit high, so I'm gonna change that to two meters, and now the effect is a little bit more manageable.
If I click on these left and right arrows here, to drag a lower value, then the effect that this bend is having is within a 1.37 meter radius, let's just make that a 1.5 meters. I just hit Enter because my default values are in meters. So that looks pretty good. Also I can change this around if I want the effect to be more pronounced.
The center of that blue ring is the center of the deformation. So I can modify this and change things around. And that happens for all of the selected polygons, when I use that Bend tool. So the other tools here work in a similar fashion. Alright, so let's take a look now at another group of tools, the Scale tool.
For this we'll use the chair Bulge and, again, I'm in Polygon selection, I'm gonna drop that tool first, the Bend tool so you know, make sure that you drop the tool, and the Polygon selection. I'm gonna click right on a polygon and then click and drag and select the different polygon faces that I will be working on.
Hold down the Shift key to select More. I'm gonna add to that selection group. So I have more things selected. So I'm gonna rotate here so I can see it a little bit better. And what I'll use is under the Scale tools towards the bottom of this list of Deformation tools, or Deformed tools, hit Bulge. I'm gonna click in the scene, and then I get this pink defector cage I guess, everything within this pink ellipsoid will be affected by the Scaling tool.
So I'm clicking on this blue box, so I'm scaling the polygons that will be affected, I'm scaling it in this blue direction, and if I scale it in the Y direction, it scales it that way. So I can quickly reshape this object. And if I move that effector sphere or ellipsoid, then it changes where the effect is actually happening.
So I'm gonna look at it from the rear view here. And then we can center that, so the effect is more centered. You can also raise it, move it in the Y direction, and we notice that bulge shape is actually going in the negative direction, and that's making it squeeze in. So there are many different ways that we can edit and deform an object. In this case, it's with the Scale tools.
So with a combination of these tools, and with a lot of practice, you can get familiar with different ways to edit an existing mesh.
