In this article, I will introduce the basic functions of how to use CLO, a 3DCAD tool software for apparel business, and how to create simulation to dress an avatar with clothes.
There will be 2 articles for this series. For part 2, I will use the avatar and T-shirt file we imported in part 1, and explain how to dress up the avatar.

Jump to Part 1
This article is part 2 of this series. If you have not read part 1 yet, please read it first.
In order to get an image of the final picture, let’s dress the t-shirt file to the avatar first.
First, please click the [Simulation] tool on the 3D screen, and start the simulation.
As in the image, as the patterns gather together and the T-shirt is dressed to the avater, the simulation starts.
During the simulation, the simulation tool will become blue, meaning it is active.
During the simulation, physics will be applied and the stitching settings will become active, and all the pattern pieces will get stitched together.
Once you see that the T-shirt got dressed properly, click the [Simulation] button again and stop the simulation.
In this article, I will explain the operations you need to do in order to do this simulation, and the stitch settings.
First, we need to undo the sample simulation we just performed.
In CLO, we can undo operations by clicking [Edit]>[Undo].
When performing this, please stop the simulation first.
This is a operation that we will use very often, so try and memorize the shortcut [⌘＋Z]（In Windows, [Ctrl＋Z]）.
If your screen matches the image above, the undo is complete.
Before stitching, first select pattern, and delete the stitch settings that are already applied.
There are 2 ways to select a pattern.
Select a single pattern
In order to select a single pattern, click on the pattern in the 2D or 3D screen.
The selected pattern will be outlined with yellow.
When you want to deselect a pattern, click on somewhere other than the pattern.
Selecting multiple patterns
When you want to select multiple patterns, you can click and drag the mouse to circle all the patterns you want to select.
Or, by pressing the [Shift] key as you click patterns will enable you to select multiple ones.
Deleting the stitch settings of the garment
In order to edit the stitch settings, we need to delete the original settings.
Click the [Edit stitching] tool, and the patterns should change like in the image.
The [Edit stitching] tool is used to edit stitch settings.
Select all patterns in the 2D screen.
Once you select all the patterns, right click and select [Delete stitching].
If your screen matches the image, your stitch settings are successfully deleted.
Then, let’s start editing the stitch settings.
It is possible to edit all of the stitching at once, and simulate the result. But we can only do so for very simple clothes, so I will explain the procedure for normal clothes, from ‘Body’ → ’Sleeve’ → ’Collar’.
Stitch the body parts①
First, we will stitch the body parts.
To edit the stitch settings, select the [Line stitching] tool.
We will start from the front body part. Select the middle line at the right front body side.
Please refer to the image above.
Next, select the middle line at the left front body side. Please refer to the GIF image. Once the stitch settings are complete, the line colours will match.
When editing stitch settings, please take care of the following.
Stitches have directions.
As in the area circled in red in the image above, the line vertical to the stitch line is the direction line.
When stitching together lines, check if the directions are the same.
If the directions do not match, the directions will cross so take care.
Stitch the body parts②
Please refer to the image below, and perform the same stitch settings.
That will be all for stitching the body parts.
You may have realized when following step ②, ③, and ④, but the T-shirt file that we imported from the library has a [Clone settings] applied, so when you edit symmetrical lines, the settings will get auto applied to the other.
I will not go on to the depths of [Clone settings], so please just take note that symmetrical line settings will get auto copied.
Simulate the body stitchs
We are done with the body stitch settings, so let’s simulate the results.
Activate the [Simulation] tool.
In the simulation, since we have not set the sleeve and collar stitch settings, those parts will not get stitched and just fall off.
We have to edit those settings, so please stop the simulation and undo the process.
Before going on with the simulation, to prevent patterns without stitch settings from falling off, let’s set a function called [Inacitve].
Select both sleeves and the collar patterns, then select [Right Click]>[Inactive (Only patterns)].
When [Inactive (Only patterns)] is active, the patterns will become transparent.
By inactivating certain patterns, those patterns are no longer simulation targets.
When we activate the simulation now, only the body patterns will be simulated.
If the body patterns are stitched together properly, it is a success.
Next, let’s do the sleeve stitch settings and simulation.
First, we need to undo the [Inactive (Only patterns)] settings we just performed.
Select both sleeve patterns, and select [Right Click]>[Active].
When active is selected, the transparent pattern will return to the original white state.
Stitching sleeve caps
We will proceed to stitch the sleeves. Please refer to the image below, and perform the stitch settings.
Stitch the sleeve bottoms, as in the red circled area in the image.
Simulate sleeve stitching
When you are done, click the [Simulation] tool.
Lastly, let’s stitch the collar too.
Before editing the stitch settings, don’t forget to activate the collar.
After activating it, please refer to the image below and perform the stitch settings.
Simulating the collar stitching
Let’s simulate the collar stitching/
If you can see that the simulation goes well, the dressing of the T-shirt to an avatar is complete.
