Now that we've created a concept model for our reciprocating saw.
00:07
It's time to evaluate our surfaces and prepare to control and refine this geometry
00:15
in fusion. We can edit T spine geometry by activating the feature on the timeline.
00:21
This will return us to the sculpt workspace where we can make our edits.
00:26
It's now time to transition the design from a concept model to a virtual prototype.
00:32
In this process,
00:33
we can make it suitable for further evaluation and
00:36
ultimately make this design ready to be manufactured.
00:42
In this lesson.
00:43
We're going to identify and discuss the many areas that we need to focus on
00:48
to improve the quality and control the design.
00:54
For starters,
00:55
the visual styles offer several options that can
00:58
allow you to better evaluate your design.
01:01
First, evaluate your design with the shaded visual style.
01:07
The shaded visual style will remove all edges and give you an uninterrupted view.
01:12
While you track highlights across your surface,
01:17
I can identify a few areas where we need
01:19
to make some changes for better surface continuity.
01:24
Next,
01:24
we will deploy some of the analysis
01:26
tools in fusion to further evaluate your geometry
01:31
in the inspect, pull down in the ribbon toolbar,
01:33
you'll find tools to analyze curvature draft and surface continuity.
01:39
I'll use a zebra analysis which will apply a
01:42
striped pattern on selected bodies to evaluate surface continuity.
01:48
The zebra analysis tool allows me to define the direction of the zebra stripes
01:53
and refine the size of the stripes by adjusting the repeats in the dialogue box.
02:00
The zebra stripes allow me to identify unintended surface continuity.
02:11
For example,
02:12
a break in the stripes would identify an area
02:15
where there's an unwanted crease in the surface.
02:26
Following the highlights of the zebra stripes
02:28
will reveal areas where the surface changes direction
02:32
and help identify defects in the surface.
02:40
Reducing the opacity of the zebra stripes is a great tool to use while
02:44
evaluating and controlling your geometry and provides
02:47
another way for feedback while designing and evaluating
02:53
before we start to edit and refine our geometry.
02:56
I'll deploy a best practice of making a copy
02:59
and moving at a known distance in 3d space.
03:03
This will ensure that we can compare changes that
03:06
I make to the current state of the model
03:08
and make it easy to move back in place as needed.
03:12
Also be sure to name your geometry in the browser,
03:15
making it easier to recall later and share with colleagues and stakeholders.
03:22
Next,
03:23
let's look at the different display modes for geometry in the sculpt environment
03:28
under utilities display mode. There are three different display types for T
03:33
blind geometry,
03:34
smooth mode
03:35
or keyboard shortcut. Control three
03:38
shows the actual model
03:41
control frame display
03:43
or control two
03:45
will display the control framework with the actual model
03:48
and box mode or control one will display the control framework.
03:55
Oftentimes it's harder to find slight imperfections while in smooth mode,
03:59
especially if you don't know what to look for,
04:07
we'll switch into box mode which will show
04:09
the frame representation of the faces we've created
04:13
and now we can much more easily identify
04:15
and ultimately refine and control this design.
04:20
There are several areas that need to be addressed
04:23
which are easily identified while displaying in box mode.
04:27
First,
04:28
you can see that the edges that define the top of
04:31
the saw are not evenly distributed and causing surface imperfections.
04:38
Next,
04:39
you can see there are several areas of the saw where
04:42
the surface topology is disjointed and the edges are not aligned.
04:46
These are causing the highlights of the geometry to move
04:49
unevenly and behind some of the poor surface continuity.
04:54
Also, there are a few T intersections in the model that should be addressed.
04:59
In this example,
04:60
we're forcing high rates of curvature change across this transition surface
05:05
and we can get better results if we subdivide and organize these faces better.
05:13
Last, there are a few star points in the model that we need to evaluate.
05:18
It is important to note that star points and T points are not bad.
05:22
And in some cases,
05:23
they are necessary when we're bringing together multiple surfaces.
05:27
But in this example,
05:28
we can likely change the location of the star point and move it out of sight,
05:32
giving us more control over the surface.
