A face group is the smallest selectable unit
00:08
on a mesh body in parametric modeling mode.
00:11
When you need to make more granular changes to a mesh body,
00:14
you can use the direct edit command to create a mesh base feature in the timeline
00:20
and enter the direct mesh editing contextual environment.
00:24
Lets make some local modifications to a mesh body
00:27
on the toolbar, navigate to the mesh tab.
00:31
Then on the modify panel, click direct edit
00:35
in the canvas or the browser select a mesh body
00:38
then click OK.
00:40
You enter the direct mesh editing contextual environment which is
00:44
equivalent to direct modeling mode within a parametric design.
00:48
A copy of the original mesh body displays in the browser in the body's folder
00:52
and a mesh base feature displays in the timeline,
00:57
the mesh selection palette displays and the selection mode is set to paint.
01:01
By default,
01:03
you can click and drag the mouse pointer across
01:05
the mesh body to select faces in specific areas.
01:10
If the size of the brush is too large or too small, you can drag the slider to adjust it.
01:15
You can check or uncheck select back faces
01:19
based on whether you want to include or avoid the undersides of faces.
01:23
As you build your selection set
01:26
in the modify selection section,
01:28
you can expand the current selection to include the entire face group
01:33
or to include all connected faces.
01:36
You can also grow or shrink the selection.
01:39
Double click to automatically select an entire face group.
01:44
Invert the current selection
01:46
or click anywhere in the canvas to clear the selection set.
01:52
You can create new face groups from custom selection
01:54
sets which is useful for fine tuning detailed regions
01:59
on the toolbar on the prepare panel, click create face group
02:04
in the canvas.
02:04
Select the individual faces you want to include in the new face group, then click.
02:09
OK.
02:10
The faces you selected are combined into a new face group on the mesh body.
02:16
If there are faces on the mesh body that are oriented incorrectly,
02:20
you can reverse the normals of the individual faces to reorient them
02:24
in the canvas. Select the faces. You want to flip
02:28
on the toolbar on the modify panel, click reverse normal,
02:32
then click. OK. And the faces you selected are flipped.
02:37
If the mesh body still displays errors or imperfections,
02:40
you can use commands like repair and re mesh to fix or refine them.
02:45
These are also applied as direct modeling operations and
02:48
their features are not captured in the timeline.
02:51
So you cant adjust their settings later.
02:54
However,
02:54
one benefit to applying multiple minor adjustments in direct modeling mode
02:59
is that you can minimize the number of features to be computed in the timeline.
03:02
When you return to parametric modeling mode,
03:07
you can also delete individual faces.
03:09
While your in the direct mesh editing contextual environment,
03:13
select the set of faces that you want to delete.
03:16
Then on the toolbar, expand the modify menu and click, delete.
03:21
Alternatively, you can press the delete key on your keyboard.
03:25
The faces you selected are deleted from the mesh body.
03:30
You can also use erase and fill to fill holes and repair regions on a mesh body
03:36
on the toolbar, expand the modify menu, then click erase and fill
03:41
double click any face along the boundary of the hole you want to fill
03:45
and all the faces along the boundary are automatically selected.
03:49
You can set the era
03:50
and fill type to uniform to fill the
03:52
hole with a relatively even distribution of new faces
03:56
and adjust the density to increase or decrease the
03:59
number of faces used to fill the hole.
04:02
If you want to minimize the number of faces used to fill a hole,
04:06
you can use the minimal racin
04:08
fill type. Instead,
04:10
you can also re mesh the area afterward to clean up the result.
04:15
Once you've made all the changes you want to make on the toolbar, click finish,
04:19
direct editing to exit the direct mesh editing
04:22
contextual environment and return to parametric modeling mode.
04:26
A new mesh base feature displays in the timeline
04:29
and a new mesh body displays in the browser.
04:32
The original mesh body is hidden in the browser
04:35
but its parametric history is preserved before
04:38
the mesh base feature in the timeline.
04:41
You can continue editing the mesh body para metrically at this point.
04:44
And new features will be captured in the timeline.
04:49
If you want to return to direct modeling mode to
04:51
make additional local modifications to the same mesh body,
04:55
you can edit the mesh base feature
04:58
in the timeline, right, click the mesh base feature, then click edit feature,
05:03
you re enter the direct mesh editing contextual environment
05:07
and the timeline marker rolls back to the mesh base feature in the timeline.
05:12
Any parametric changes you applied after the
05:14
mesh base feature are temporarily rolled back.
05:17
While you edit the base feature.
05:19
When you finish direct editing and return to parametric modeling mode,
05:23
the changes you made to the mesh base feature are applied to the mesh body
05:28
and the operations that follow the mesh base feature recompute
05:32
to incorporate the new changes into the downstream parametric features.
