Modeling could be hard or even scary when you don’t have any idea of how to start. So, don’t be afraid anymore because the time has come to face your Mesh Object and transform it into that fabulous design you have in mind.
First of all, remember that a Mesh Object is composed of vertices, edges, and faces, and you can select them in the Edit Mode. This way, you can use all the shortcuts to convert a Mesh Object to whatever you want.
Go ahead! Select a group of faces: click G to grab it, and move it with the mouse to the place you want.
In the case of faces, you can press R, which is the shortcut to the rotation tool. Then, see how that selection is the only one that turns while the rest of your model remains intact.
And you can also scale the selection you just did by pressing S on your keyboard and dragging it.
You can do the same with edges, but if you have a single vertex selected, you can grab and move it, but the rotation and scale tool won’t be available, so they won’t have any effect. But, again, that’s because a single vertex doesn't have the properties to use those tools; it just has a location value.
Note: You can check the properties on the bar side panel that you can bring out by pressing N.
Don’t forget that Mesh Objects are only the guideline for more complex designs; for example, you can transform a simple sphere into a teardrop. You can use the Front Orthographic view for a more technical perspective of what you are changing by pressing the number 1 on your keyboard. After that, select the vertex at the top center of your sphere and press G + Z (Z because this way, you tell the program that you’re only going to move that vertex on the Z axis), then move it up.
Select the loop of vertices that follow the first one, move it up, and by pressing S, you will give them a proper size. Repeat this process with the vertices below until you think you’ve done it.
Tip: To check the model is going, you can switch between Edit Mode and Object Mode.
Another way to transform a mesh object is using Proportional Editing. So, go to Edit Mode, select the vertex in the top center, press O on your keyboard, and notice that on the top of your screen, it turns on a light, which means the Proportional Editing is now available. You can switch it on or off by clicking the icon or shortcut.
Now you can press one again to return to the frontal orthographic view and press G + Z as you did before. However, this time you’ll discover that there is a black circle just in the middle of your model, which is the influence of radiance that will help you move up all the loops automatically.
Notice that the bigger the black ring, the more edit radius you will have. On the other hand, if you make it smaller, the edit influence will be. You can expand or decrease this tool's size by scrolling your mouse's wheel.
Now you can transform any kind of Mesh Object more easily! Remember: don’t let anything stop your creative process. Good Luck!
