00:00:12,050 --> 00:00:15,150
Welcome to the world of computer aided design, the punishment.

2
00:00:17,180 --> 00:00:22,130
We are going to learn how to extend entities in extreme danger.

3
00:00:22,730 --> 00:00:24,880
We need to use external entities.

4
00:00:25,630 --> 00:00:33,560
Stool is available here in the external entities to be used to exchange this case came to be to.

5
00:00:34,100 --> 00:00:39,140
The next book in this entity is extended up to its decision.

6
00:00:39,750 --> 00:00:42,910
Another entity, Pottermore, allege it was an.

7
00:00:43,380 --> 00:00:44,240
This line segment.

8
00:00:44,990 --> 00:00:45,520
This line.

9
00:00:46,310 --> 00:00:50,800
What I would do is activate the external entities to keeping on it.

10
00:00:51,430 --> 00:00:53,840
And I will click on Doppler of this, Nancy,

11
00:00:56,800 --> 00:01:01,350
and see the next available intersecting entity with this line segment.

12
00:01:04,370 --> 00:01:06,260
I will again click at this line segment.

13
00:01:08,720 --> 00:01:13,870
So that it goes up to the next level intersecting entity, which is dismantling.

14
00:01:15,550 --> 00:01:21,280
Now, if I tried to extend this line further, I would give them a warning message that this element

15
00:01:21,340 --> 00:01:22,500
cannot be extended any.

16
00:01:23,640 --> 00:01:27,170
There is no intersecting available at this is facing.

17
00:01:28,950 --> 00:01:32,230
Lambic, I can exchange this up with this line segment.

18
00:01:32,450 --> 00:01:33,660
I simply picking.

19
00:01:34,740 --> 00:01:36,820
This is how you exchanging these?
