How to use the autoForma modeling tool in the Spentys iOS application?

AutoForma is the tool that will enable you to get an automatic standard design on your scans for A, W, and H Models. This guide will explain to you how to use it easily.

AutoForma, unlike freeForma, will automatically model for you an already designed orthosis.

If you have classic pathologies to which a constant model corresponds, this is the tool for you. If, on the other hand, you wish to have more freedom in the creation of the brace via Freeforma, for example, to draw dimples on a scar or a sensitive area, you can follow our modeling guide via FreeForma.

With 4 steps, Autoforma will model the perfect orthosis for you in a few minutes.

The 4 steps process:


Landmark positioning	Design customization	Thickness and offset options	Beltloops positioning

1. Land mark positionning

The first step is simply to place landmarks on the scan as in the scan correction step.

To do this in the easiest way, use key views such as the inferior view to place the fingertips on the chain and the dorsal view for the metacarpophalangeal joints.

2. Design customization

The first step when having the template applied to the corrected scan is adapting the length of the device as well as the boundary width.

The boundary width can be used to ensure enough space along the edges of the device to place the beltloop, but also to make sure the device is rigid enough to support the patients limb regardless of the alveoles.

When 'pattern off' is enable, the alveoles will be closed.

The second step of the fitting is to adapt the alveole pattern. By clicking on one of the Alveoles you'll get the possibility to adapt the width and density of the alveoles.

By adapting these parameters, you'll get the possibility to make the alveoles bigger or smaller, also leaving the device more flexible or rigid.

Lastly, before moving on to the finishing step, we'll have the possibility to adapt the trimlines. If you click on the trimlines (thick grey lines), small nodes will appear allowing you to modify the trimlines.

It might take some time before the trimlines regenerate.

3.Thickness and offset options

In this modeling stage, you will have two possibilities. If the toggle is 'off', you'll be able to adapt:

Thickness: Increase or decrease the thickness of your splint
Offset: Increase or decrease the thickness of your splint. Offset means the gap you'll get between the scan and your orthosis

If the toggle is 'on', you'll be able to adapt:

Boundary thickness: increase or decrease the thickness of the edge of the splint.
Boundary flare: Choose to curve the boundary external to avoid pinching.

4.Beltloops positionning

The last step of the modeling process will be to position your beltloops on the brace.

To do this you can press on the beltloop you want to modify, it will change color. You can now drag it along the edge of the brace and modify it via the tabs at the bottom of the screen:

Length
Clearance
Width
Thickness
Straight/curved toggle: Change the shape of your beltloop, make it straight or following the shape of the trimline.
Trash Can: Delete this beltloop.

5. Rivet holes or mushroom pin

It is not necessary to only have beltloops to close the device. Some of our customers prefere to use rivets on one side of the splint and work with rivet holes on the other side.

How to add the rivet holes or mushroom pins?

Choose if you'd like to add a rivet hole and/or a mushroom pin (be aware: this can only be printed with the MJF technology).

After Clicking on the '+', you'll be able to select the area where you want to add the hole or pin.

After validation for the placement, you can select 1 or all rivets/pins at the same time and adjust the circonference.

Congratulations! You are now able to create easily a consistent orthosis that will be easily printable and ready out of the oven!
