Join Henry Santos for an in-depth discussion in this video Tools to add polygons and detail, part of MODO Essential Training.
- [Instructor] Now that we've built a number of 3D models, let's go through the process of adding detail and adding more polygons to this. So we're gonna start from scratch and create a chair. So from a new file that's untitled, let's go ahead and go to the basic tool set, and go and create a new cube. So, while we have a mesh selected, we see that in our item list here, we have a mesh that's empty, let's go ahead and hover over the cube tool, and then hold down the control key.
If you notice, there's a green grid that shows up behind it. And if you hover over it, it says control unit cube. So it creates a unit cube. So if you click on that, that is a one meter be one meter by one meter cube at the very center. That will work for what we're trying to do. While that mesh is selected, let's make sure we're going to the polygon selection mode, or we're using the polygon selection mode. And we'll hover over the bottom plane here.
Click on that, and move that up. Follow along. And I'm gonna double-click on this one polygon up here. And scale it in. Hit the R key to scale. Not really too concerned about the size of things, because I just want to go through the process of adding detail. So while we're in polygon selection mode, you can see here that we can select a polygon.
Select the top polygon. And let's add a little bit more detail to the top here. So while I have that selected, we'll go over to our polygon set of tools. There it is. And as we've seen before with the primer, we've used the bevel tool before. So we'll just go back up, second from the top, hit bevel. I use this tool all the time. So it's a very common tool, and a lot of people use it.
So I'm gonna click on this red handle and it shrinks the borders of this polygon in. And so we can look at the tool properties underneath bevel. We have inset. So we can manually set that by clicking and dragging the left and right sliders there. Slide from left to right with the clicking and dragging. Or we can enter in a value. So we can say inset this at 50 millimeters. Hit enter.
There it is. It's set to 50 millimeters. And we'll click on this blue handle to raise it up. So you notice again, if we go back to the tool properties, we can shift it up and change that value as needed. 30 millimeters. While this still is active, we can hold down the shift key and click again, so that re-initiates that tool. So I held down the shift key while the bevel tool was still active, clicked in there, dragged it up.
Cool, so let's add a back to this. So I actually want to add a seat back right back here on the very top polygon. So we need more polygons. So what we'll do is go to the edge selection mode, change to edge selection, and then click on one of the edges and I need to create, essentially, a cut line to add more polygon.
Then, under the mesh edit tools, we have loop slice. So the loop slice feature will allow you to create edges. So using these default settings, move, the mode is free, count is one, and we'll just go ahead and click on that edge. Because it's set to free, I can place this wherever I want it to go.
If it was set to uniform, it puts it right in the center. And if you notice this pop-up value here on the screen, it says 50%. So this is an onscreen definition of what the value is of where this is located along that edge. It says 50%, which means it it uniformly placed on that line. So I want to set this back to free. And drag, because the tool is still active. So I hit that.
And I drop the tool by hitting the space bar. And now I have this other polygon that I could work on. So I'll go back to my polygon selection mode. At this point I'm just going to hit the key command to switch to polygon selection. And, of course, it remembers a previous selection. So now I am selecting this back edge. Let's go back to our polygon tools, hit bevel, click in the space, and drag up.
Shrink that in. Use the move tool now. When I click on the move tool, it drops the previous tool and allows me to just modify this polygon as a polygon. So there is makings of our chair. So I want to add feet to the bottom. So what I'll do is go back to my edge selection.
Click on this edge. I want to add a line going across there. Going across the chair itself. So I'll go back to mesh edit. Loop slice. And set that. And what I wanna do next is add a couple loop slices looking on either side of this chair.
I want it to be symmetrical. So I'm gonna rotate my screen so I can see the bottom of this, because the legs will be coming out from there. So I click on one edge, and I'm gonna cut across that, but I wanna make it symmetrical, so I'm gonna click on the loop slice tool again. But change the mode from free to symmetry. So I'm gonna click on there. It only shows one, because my count is set to one.
So, let's change this count to three. And I'm gonna click in the screen, and that will allow me to symmetrically scale that slice. So I'm gonna drop the tool. Now I have these four corners. I'm gonna shift select while I'm in polygon selection mode. And then go to my polygon tools, and do yet another bevel.
Click in there. But this time I just want it to go vertically, so I clicked once. So I made duplicates there. So I can use the move tool and drag it down. We have a chair. And because we have our project set to Chapter 3, if you want to save this, you can save this file, and it goes directly to that scenes folder. So with the vast amounts of tools for editing your polygon model, you have a lot of options on how you can create your meshes.
