Fixing constraints in DWG.
1
00:00:09,60 –> 00:00:12,400
ARES Commander 2015 is getting even smarter
2
00:00:12,580 –> 00:00:19,20
thanks to the tools that allow us to assign parameters to “parts” of the drawing or the drawing in general.
3
00:00:19,340 –> 00:00:23,740
In this example, we have a mechanical part containing various constraints,
4
00:00:23,900 –> 00:00:27,419
which are assigned to different elements of a drawing
5
00:00:28,320 –> 00:00:30,360
By changing this value
6
00:00:30,780 –> 00:00:33,560
or this value, you change the drawing.
7
00:00:34,300 –> 00:00:39,800
The CONSTRAINT we have here allows us to determine the position or shape of an object.
8
00:00:40,540 –> 00:00:43,40
And even how objects relate to one another –
9
00:00:43,240 –> 00:00:48,800
because Ares Commander 2015 is the smartest version that exists so far.
10
00:00:49,380 –> 00:00:51,40
Look at this example.
11
00:00:51,440 –> 00:00:53,360
When you edit this value
12
00:00:57,230 –> 00:01:00,410
and press ENTER the whole drawing changes.
13
00:01:02,20 –> 00:01:04,20
Now we can change this one.
Mechanical is composed of many constraints
14
00:01:10,880 –> 00:01:16,979
In this other example, we can see how a mechanical part can be composed of many constraints.
15
00:01:17,230 –> 00:01:22,210
Among the available tools, we have the option to hide all constraint icons.
16
00:01:22,340 –> 00:01:25,380
In this case, the mechanical part has been
“cleaned”.
17
00:01:26,100 –> 00:01:28,759
But the constraints are still there.
18
00:01:29,520 –> 00:01:33,640
When selecting an item, you see the constraint assigned to it.
19
00:01:35,560 –> 00:01:38,880
Selecting all, we see all constraints again.
20
00:01:41,140 –> 00:01:45,740
If we go here, we see the value of the radius is 60 units.
21
00:01:47,000 –> 00:01:49,000
Let’s change it.
22
00:01:50,940 –> 00:01:53,740
We edit its size by dragging this grip.
23
00:02:00,160 –> 00:02:03,140
We can see that the entire appearance has changed,
24
00:02:03,360 –> 00:02:06,820
since all its components are related to this parameter –
25
00:02:07,20 –> 00:02:09,500
which is the modified diameter value.
26
00:02:09,780 –> 00:02:14,380
By changing the radius, we have changed the position of the circle.
27
00:02:14,760 –> 00:02:18,200
This also affects the position of the teeth.
28
00:02:19,000 –> 00:02:22,960
Now, let’s see a different example of how to work with constraints.
29
00:02:23,580 –> 00:02:26,560
For example, we can draw a circle
30
00:02:29,180 –> 00:02:32,840
and assign a constraint to the diameter.
31
00:02:40,300 –> 00:02:43,560
We for example assign the value “5”.
32
00:02:46,300 –> 00:02:48,780
When we try to modify this circle,
33
00:02:49,380 –> 00:02:56,560
it is not possible because we assigned a specific constraint to the diameter, which determines its shape.
34
00:02:57,460 –> 00:02:59,860
Note that the value appears locked.
35
00:03:00,220 –> 00:03:01,300
To change it,
36
00:03:01,700 –> 00:03:03,299
we have to select the constraint
37
00:03:03,460 –> 00:03:08,460
that conditions the diameter and the grips belonging to this constraint.
38
00:03:10,580 –> 00:03:14,220
Like this, yes, we can modify the diameter.
Using parameters tool
39
00:03:17,120 –> 00:03:22,320
Here we have the parameters tool, with which we can control the constraint.
40
00:03:23,480 –> 00:03:26,760
For example, we can type a new value.
41
00:03:27,940 –> 00:03:31,420
In another example, we have a circle and 2 lines.
42
00:03:32,220 –> 00:03:35,900
Now, thanks to the constraint, we can do two things:
43
00:03:36,740 –> 00:03:42,160
We first can assign a constraint to the diameter or radius of the circle.
44
00:03:52,460 –> 00:03:55,760
Then we can assign a tangent constraint to the lines.
45
00:03:57,140 –> 00:04:02,279
To do this, first select the item that should remain “fixed” in place.
46
00:04:02,760 –> 00:04:06,000
First select the circle and then the line.
47
00:04:06,400 –> 00:04:08,900
Notice that the constraint icon appears.
48
00:04:09,360 –> 00:04:12,30
Repeat the process with the lines.
49
00:04:13,720 –> 00:04:20,220
By selecting parameters, we can change the radius of the circle. For example, 3.5.
50
00:04:24,600 –> 00:04:27,660
In another example, we have a polyline.
51
00:04:28,80 –> 00:04:31,300
Here we can assign constraints to the angles.
52
00:04:32,80 –> 00:04:34,460
Let’s select the first 2 sections.
53
00:04:36,140 –> 00:04:38,960
We see it has an angle of 38 degrees.
54
00:04:39,180 –> 00:04:40,880
We change it to a new value,
55
00:04:41,20 –> 00:04:43,20
for example “40”.
56
00:04:44,580 –> 00:04:49,820
Now we can define other constraints between these 2 sections and assign a new value.
57
00:04:50,380 –> 00:04:52,240
For example, “60”.
58
00:04:54,440 –> 00:04:57,40
Next, when we move the grips of the polyline.
59
00:04:57,620 –> 00:05:03,580
We see that the image changes always with respect the constraints specified in the angles.
60
00:05:08,460 –> 00:05:11,239
In this new example, we have 2 rectangles.
Adding contraints
61
00:05:11,740 –> 00:05:16,300
We can add a distance constraint to the separation between them.
62
00:05:21,400 –> 00:05:24,280
Selected the constraint, then the elements.
63
00:05:25,820 –> 00:05:28,580
We can vary the distance value.
64
00:05:30,660 –> 00:05:36,280
When doing so, the locked icon appears, and we see the distance constraint to the separation.
65
00:05:38,120 –> 00:05:42,940
When you move one of the rectangles,
66
00:05:45,480 –> 00:05:50,280
the side of the other rectangle will also move to maintain the distance condition,
67
00:05:52,960 –> 00:05:55,219
although the rectangle deforms.
68
00:05:55,920 –> 00:05:58,720
If we want the whole rectangle to move at once,
69
00:05:58,740 –> 00:06:02,460
we have to assign a constraint between the sides of the rectangle
70
00:06:03,280 –> 00:06:05,20
For example,
71
00:06:06,200 –> 00:06:10,360
we generate a constraint to the right angle between two sides.
72
00:06:10,800 –> 00:06:12,380
Now try it.
73
00:06:13,160 –> 00:06:18,520
Move the rectangle and see that the other one follows without any deformation.
Another Example
74
00:06:19,120 –> 00:06:20,500
A new example.
75
00:06:20,960 –> 00:06:24,900
We can create circles that remain concentric to each other.
76
00:06:25,660 –> 00:06:28,520
We therefore use this geometric constraint.
77
00:06:30,500 –> 00:06:35,460
When we select the circles, they stay concentric which is maintained by the constraint.
78
00:06:40,420 –> 00:06:45,640
If we need to move the smallest circle, they all move with it,
79
00:06:47,900 –> 00:06:49,979
because they stay concentric.
80
00:06:50,880 –> 00:06:54,560
Now we can ask these lines to stay parallel to each other.
81
00:06:55,40 –> 00:06:59,840
After selecting the constraint, select the first line that will be the guide,
82
00:07:01,200 –> 00:07:06,240
In this example, we use the equality constraint that appears here.
83
00:07:08,240 –> 00:07:10,660
In this case we have 2 lines.
84
00:07:11,160 –> 00:07:13,160
Select the first,
85
00:07:14,80 –> 00:07:18,560
select the second, and it will be the same length as the first one.
86
00:07:19,560 –> 00:07:20,720
But not only that
Finding distance constraint for a dimension
87
00:07:20,980 –> 00:07:24,200
As there is an equalitiy constraint between them,
88
00:07:25,40 –> 00:07:27,520
when we select one of these lines
89
00:07:28,220 –> 00:07:29,960
and extend it,
90
00:07:31,280 –> 00:07:34,39
it directly affects the other one.
91
00:07:34,780 –> 00:07:38,659
In the case of these arcs, we create anequal radius.
92
00:07:39,140 –> 00:07:43,39
To do this, select one arc and then the other.
93
00:07:44,200 –> 00:07:46,280
The radius is equal.
94
00:07:47,400 –> 00:07:49,919
Now we can drag a grip of one arc.
95
00:07:50,640 –> 00:07:52,640
Change the radius
96
00:07:52,740 –> 00:07:57,300
and it will automatically affect the other arc.
97
00:07:58,140 –> 00:08:02,479
Finally, we can also create a dimensional constraint with this icon.
98
00:08:06,200 –> 00:08:09,380
Like this we get a distance constraint for a dimension.
99
00:08:09,960 –> 00:08:14,359
