After receiving feedback from other engineers,
00:06
it was determined that the ribs and wall thickness were too thin
00:13
because we had created the user variable.
00:15
We can quickly go back and change the rib thickness from 0.1875
00:21
to 0.25.
00:27
Notice that it changed the thickness of the ribs.
00:30
But because of that change,
00:32
one of our delete face features has turned red,
00:35
signifying an error.
00:38
This is easy to fix.
00:40
We can just edit the delete face feature
00:43
and select the faces that need to be added
00:45
to make the delete work correctly.
00:55
We can now see that the delete feature is no longer read in the timeline.
01:00
This shows that even though making a change may cause an error in the timeline,
01:06
it is easy to fix.
01:10
Looking at the back of this component,
01:12
we want to remove some weight again, using the shell command
01:16
again,
01:17
we want to control how deep the shell goes
01:20
and we don't want to shell the section where the linear guides are.
01:24
So we will split the body to help control this.
01:31
Now we can show this face and use rib thickness as the distance variable.
01:40
Notice the wall thickness is the updated 0.25.
01:47
Using the combined join command.
01:50
We will make this all one part. Again,
01:58
we want to add some strengthening webs in this section also.
02:02
So we need to create a profile with some basic lines
02:07
in the marking menu.
02:09
You notice that when you drag down,
02:11
it opens the sketch commands
02:13
and that the line command is at the bottom
02:15
or the six o'clock position.
02:18
This means if we just drag straight down,
02:21
we will get the line command gesture
02:38
using the S key dialogue.
02:40
We can search for the web command
02:46
again.
02:47
We'll use the rib thickness variable to define the thickness of these webs.
02:56
We'll do a rule filet on the web feature to round over the edges, 0.25
03:13
by dragging straight up with your right mouse. Click,
03:16
the marking menu repeats the last command.
03:19
In this case, the rule filet command,
03:24
we'll select the inside faces to make sure all of the edges are rounded over.
03:31
You can see how the rule Philip command saves
03:34
time by selecting many of the edges for you.
03:37
Instead of you having to pick each one manually
03:47
to counterbalance this part.
03:49
And to add some extra material, we want to add some more geometry across the top.
03:54
Here,
03:56
we will use the draft command to angle this face.
04:05
We'll select this horizontal plane for the draft plane
04:09
and then select the face to be angled.
04:13
However,
04:14
you notice that it wants to draft the whole face. And this is not what we want.
04:20
By selecting two sides,
04:23
we can control the draft on both sides of the draft plane.
04:28
So we can angle the top side 15 degrees
04:32
and keep the bottom side vertical at zero degrees.
04:38
Also
04:39
notice how the filets extended automatically.
04:45
We don't want a sharp edge here. So we should fill up this edge.
04:53
Finally,
04:54
we need to project the whole locations from the linear slides onto our component.
05:00
When we project,
05:02
let's change the project option to project the whole body
05:06
instead of individual edges.
05:10
That way it will project all the holes at once
05:13
and it won't require us to select multiple edges.
05:19
Let's isolate our component. So it turns off all of the other components
05:28
using the whole command from the marking menu.
05:31
We can select one of the whole locations.
05:40
We'll set the depth to one inch.
05:44
The preview uses a default size.
05:47
So we can again use the measure command in the dialogue
05:50
to capture one of the projected holes. For reference.
05:55
We can choose to do one hole or many holes from a sketch.
06:10
We want these holes to be threaded.
06:12
So we can bolt the linear slides to our component
06:17
will use the thread command and select one of the holes.
06:23
Notice how it figures out automatically that this will be a 5/16 by 18
06:29
due to the existing size of the hole.
06:38
One of the nice things about the timeline is that we
06:41
can always go back and make a change if necessary.
06:46
In this case, we want to change the holes to have a countersunk edge.
00:03
