Practice exercise

00:01

This is a practice exercise video solution.

00:07

For this practice, we want to get started with the supplied dataset lofted handle - PE.

00:12

We're going to be creating a handle on the current cup that we see in the design.

00:16

We're going to get started by first creating an offset construction plane.

00:20

In this case we want to select the top plane or in this case the XY plane.

00:25

I'm going to rotate to a front view and I want to pull this plane until it's in the middle of this area where our handle will be.

00:32

This will be roughly 40 mm and we can say, OK.

00:36

Next, I want to create a new sketch, making sure that I can still see the sketch for my handle.

00:44

I'm going to use my line tool to go from one of these points on the sketch and you'll notice that nothing is able to be snapped to.

00:51

We're going to have to use project in order to bring those into our current sketch,

00:55

but we'll just place it roughly to the side and drag it out into the right a distance of 50 mm.

01:01

Let's hit Escape on the keyboard.

01:03

Go to Create, Project/Include and Project.

01:06

We simply want to bring the center point of the slot and say, OK.

01:11

Now we can drag and drop our horizontal line on to that point, select it and make it construction.

01:19

The main shape of the handle is going to be a slot but we want to taper it down at the position where it will be held.

01:25

So we're going to use the slot tool.

01:27

And in this case we want to use a center point slot because we have a center point for our selection.

01:32

We're going to start here begin dragging off to the right about 7 mm.

01:36

And then we're going to drag out until it's about 8 millimeters.

01:41

We use our dimension tool to give this a vertical dimension of 14 mm and then we'll dimension the radius value at 4 mm.

01:50

Now we can finish the sketch and we want to create a sketch that goes through all of these points.

01:56

So we're going to start a new sketch and this is going to be on our XZ plane.

02:01

Once we start this process, let's use the sketch palette tool slice so we can see inside of the cup.

02:07

We're also going to use Project/Include, going to Project/Include we'll use project.

02:11

And once again we want to grab the center point of these slots and the center point of our new slot sketch.

02:17

We'll say OK.

02:18

To make sure that we've grabbed the correct thing, we can hide Profile 1, Profile 2 and Sketch 6, which we just created,

02:25

to make sure that we do have those centerpoint references.

02:28

From here, we're going to use our spline tool.

02:31

Using the fit spline, we're going to start at the first point, select the second point and come down to the third point,

02:37

and then use the green check mark to OK and Escape to get off the spline tool.

02:42

We can select the green handles.

02:44

We can add dimensions or constraints to them, for example making them horizontal or making them vertical.

02:52

Going to hit Escape to get off my constraint tool.

02:55

Then I want to begin adjusting the influence or the tangency of each of these positions.

03:01

If you like you can use dimension tools by selecting sketch dimension and giving an overall dimension between these two points.

03:08

I'm going to use 40 mm on the top.

03:12

I'm going to use 60 mm on the bottom and for this vertical line on the right side, I'm going to use 22 mm.

03:22

We're going to finish the sketch and now we want to make sure that we bring back Profile 1, Profile 2 and Sketch 6.

03:28

We're going to be using all of these to create a loft.

03:31

We'll go to create, select loft and began by selecting our first profile.

03:37

Note when we do this, it's trying to select only half because it has a vertical line in the middle.

03:42

We want to make sure that both of these regions are considered Profile 1.

03:47

We use the plus icon to select Profile 2.

03:50

The plus sign icon again to select Profile 3.

03:54

We want to make sure that we are joining with the cup and we're not removing material.

03:59

To add a guide rail, we can use the center line guide rail option, use the plus icon and select our sketch.

04:06

We can see here that this allows us to create that loft and it tapers down in the middle based on our profile.

04:12

We can say OK and allow it to join to the cup.

04:15

This leaves some small remnants on the inside, but these can be removed by using direct modeling tools.

04:21

In this case, I'm going to hold down the left mouse button to select the face underneath that we can't see,

04:26

while holding down shift and then use delete on the keyboard.

04:31

I'll do the same thing down here, holding down the left mouse button to select the face that we can't see.

04:35

Then using shift control or command to select all the others and delete on the keyboard.

04:40

This allows me to remove that reference on the inside.

04:45

Now this geometry can be mirrored or pattern around the rest of this mug.

04:48

But for now let's go to our home view and make sure that we do save this design.
