In this video I’ll create this pitcher using a few surface modeling commands.
00:09
I’ll start with these objects to create the body, spout, and handle for the model.
00:15
I’ll be using the 3D Modeling workspace with the Realistic visual style.
00:21
From the Surface tab, I’ll select Revolve and revolve this spline around the centerline.
00:28
I’ll select the spline and press Enter.
00:31
For the axis, I can give two points along this center line
00:36
or I can press Enter and select the centerline and enter 360 for the revolution angle.
00:43
I’ll hold down the Shift key and the mouse wheel button
00:45
while moving the mouse to change the view of the model.
00:49
When creating 3D models you’ll find that you pan, and zoom, and change the view a lot.
00:54
Looks good so far.
00:56
Now I’ll extrude this circle into the body of the pitcher.
01:00
I’ll use a solid that will be used to trim the surface and form the cutout for the pour spout.
01:06
From the Solid tab I’ll select Extrude.
01:10
I’ll select the circle, press Enter, and drag to create the cylinder for the spout.
01:16
I want the cylinder to go into the body of the pitcher but not through the bottom.
01:21
Next, I’ll subtract the spout from the body to trim the surface.
01:26
I’ll select Subtract and select the body of the pitcher and press Enter.
01:31
This Task Dialog informs me that using a solid and a surface together
01:36
in some cases is not an ideal action.
01:39
In this case I am using the solid as a throw away object
01:42
so I click to continue the subtraction.
01:45
I’ll select the cylinder and press Enter.
01:48
I’ll create the spout using the Loft command
01:51
to create a loft surface between the edge of the trimmed surface
01:54
and the spline for the top of the spout.
01:57
From the Surface tab I’ll select Loft.
02:01
Pressing the Ctrl key allows me to select the trimmed edge of the surface.
02:06
Now I’ll select the top edge of the spout and press Enter to create the surface
02:11
and Enter again to accept the defaults.
02:14
Next I’ll use Sweep to create the handle of the pitcher.
02:19
First I’ll select this object for the profile of the handle and press Enter,
02:24
then the path I want the profile to follow.
02:27
With the handle created our pitcher is really starting to take shape.
02:32
I’ll use Trim to trim the handle flush with the body of the pitcher.
02:37
I’ll select the handle and press Enter,
02:39
then the body of the pitcher for the cutting edge and press Enter.
02:43
Now I’ll select the piece of the handle inside the pitcher to trim.
02:48
Our pitcher is really looking good but we need to complete the bottom.
02:52
I’ll use Patch and select the edge of the pitcher and press Enter to create the bottom,
02:58
and press Enter again to accept the defaults.
03:02
I’d like to create a base on the pitcher so it stands off the table.
03:06
I’ll offset the patch to give the base a little height.
03:11
The arrows indicate the direction of the offset.
03:14
If needed, I can use the Flip option to change the direction.
03:19
I’ll enter .75 for the offset distance and press Enter.
03:24
Now I’ll blend the bottom of the pitcher with the body.
03:28
I’ll start by erasing the original base surface that is no longer needed.
03:33
I’ll select Blend and select the edge of the bottom surface as the first edge and press Enter,
03:40
then the edge of the pitcher as the second edge and press Enter.
03:44
Now I’ll use the continuity grip to adjust the continuity
03:47
and the bulge magnitude of the surface.
03:51
This will adjust how the two surfaces blend together.
03:54
For continuity I’ll select G1 for the first edge and G2 for the second edge and press Enter.
04:02
Next I’ll select the bulge magnitude, and type 3 for the first edge,
04:06
and 1 for the second edge, then press Enter.
04:10
This will give the base a nice taper.
04:14
With just a few surface commands I was able to create this nice looking model.
