In this video, I’ll create this mesh object. Before I get started I’ll change to the
3D Modeling workspace. This gives me easy access to the most commonly used 3D modeling
tools. Now I have the Solid, Surface, and Mesh tabs available on the ribbon.
Because 3D models are easier to create in an isometric view, I’ll select SW Isometric
from the Viewport Label menus. I could also click the corner of the ViewCube tool.
Next I’ll select the Wireframe visual style from the Viewport Label menus to make sure
I can see all edges of the model. Now I’m ready to get started.
First, I’ll select the Mesh tab, then the dialog box launcher, and set the number of
tessellation lines. Mesh objects are divided into multiple faces. I can adjust the number
of faces by changing the number of tessellation lines.
To create my Mesh object, I’ll start with a mesh primitive--in this case, a mesh box.
I’ll draw the mesh box, giving it a length, width, and height.
Next, I’ll select the mesh box, right-click, and select Smooth More. I’ll repeat the
Smooth More command by pressing Enter two more times to increase the smoothness of the
mesh to Level 3. Now I’ll reshape the mesh object. I’ll
hold the Ctrl key and select the faces I want to edit. I’ll use the Move Gizmo to move
the faces I selected. Notice the yellow highlight on the gizmo? This indicates whether the movement
will be constrained along the X, Y, or Z axis. Next I’ll right-click over the Move gizmo
and select Rotate Gizmo to add more curve to the object. Now the yellow highlight shows
the plane of rotation. I’ll use Add Crease to remove the smoothness
from the selected faces and create sharp edges. Next, I’ll select the mesh object, right-click,
and select Refine Mesh to increase the level of smoothness.
To get a better idea of how my mesh will look, I’ll select the Conceptual visual style
from the Viewport Label menus. Finally, I’ll hold down the Shift key and
mouse wheel button while moving the mouse to orbit around my mesh object.
