00:00:00,080 --> 00:00:04,120
Construction
geometry is a great category of commands.
1

2
00:00:04,400 --> 00:00:09,080
Some examples are the possibility
to sketch where no plane or face exist,
2

3
00:00:09,080 --> 00:00:11,320
and the possibility to combine
construction
3

4
00:00:11,320 --> 00:00:14,600
geometry with other commands,
such as the cutting tool.
4

5
00:00:15,320 --> 00:00:19,680
You have got construction planes,
construction axes and construction points
5

6
00:00:19,680 --> 00:00:24,720
at your disposal, and within each category
you find a set of commands.
6

7
00:00:25,000 --> 00:00:28,040
This gives you great flexibility
when you sketch.
7

8
00:00:29,080 --> 00:00:32,080
Let's start with a simple offset plane.
8

9
00:00:32,200 --> 00:00:35,400
Select
the face and your extent type to place it.
9

10
00:00:35,680 --> 00:00:38,680
You now have a new plane to work with.
10

11
00:00:43,440 --> 00:00:44,000
Construction
11

12
00:00:44,000 --> 00:00:47,000
Plane at an Angle works
a little differently.
12

13
00:00:47,160 --> 00:00:50,920
Select a linear edge, axis or sketch line
13

14
00:00:50,920 --> 00:00:53,920
and then select your angle.
14

15
00:00:58,520 --> 00:01:01,320
It's obvious that you can use
construction planes
15

16
00:01:01,320 --> 00:01:05,320
as sketch surfaces,
but they're good for other things as well.
16

17
00:01:07,080 --> 00:01:10,400
Here I use a construction plane
as splitting tool,
17

18
00:01:10,400 --> 00:01:13,400
and divide my body into two bodies.
18

19
00:01:17,720 --> 00:01:19,760
Sometimes you need a new axis.
19

20
00:01:19,760 --> 00:01:24,120
The X and Y axis in the origin
are, for example, great
20

21
00:01:24,200 --> 00:01:25,760
to combine with other commands
21

22
00:01:25,760 --> 00:01:29,600
such as the circular pattern tools,
or when you work with joints.
22

23
00:01:29,600 --> 00:01:33,320
Use Construct and Axis
through for two points,
23

24
00:01:33,320 --> 00:01:36,320
to set up a custom axis.
24

25
00:01:45,040 --> 00:01:46,000
A reference point
25

26
00:01:46,000 --> 00:01:49,000
can be a helpful aid in your work.
26

27
00:01:49,200 --> 00:01:52,200
With Point along paths,
you just have to select a path
27

28
00:01:52,200 --> 00:01:55,280
and either a proportional
or physical distance.
28

29
00:02:00,400 --> 00:02:01,000
Now you know
29

30
00:02:01,000 --> 00:02:04,000
the basics about construction planes.
30

31
00:02:04,040 --> 00:02:07,040
Keep moving forward
and see you in the next lesson.
31

32
00:02:07,280 --> 00:02:07,720
Thank you.
