Finally! A HoloLens 🕶️ guide! 😁 Get your HoloLens ready to start!

0.1 Please use the same assembly as you used for the Parts 1-3 or a new assembly, but make sure that it's a simple one.

We will kindly ask you to refrain from using complex assemblies and stick to the simple ones, such as a column or a beam. You can see the examples above:

We will teach you how to work with complex assemblies in the advanced guides later on 😉

Welcome to your first FabStation HoloLens guide! Here is your learning plan for today:

HoloLens basic actions (unless you chose "Yes" on the previous page)

Step 1: Navigate to the HoloLens within the tablet

Step 2: Adjust the Hologram Orientation and Place the QR code

Step 3: Mapping the area

Step 4: Align an assembly

Basic HoloLens Actions

The HoloLens 2 is a new and different hardware device that is easy to use once you learn the basic interactions and settings.

We will ask you to look through the options below to make sure that you are aware of them

Step 1: Navigate to the HoloLens within the tablet

To start aligning an assembly, you need to navigate to the HoloLens using tablet.

1.2 Select either Fabricate, Inspect (if you use status system) or View from the Home screen.

If you are not sure or don't use status system, please select View.

1.3 Choose the project and locate your assembly

1.4 Once you selected an assembly, click on Auto-Fab and choose the HoloLens device:

See the same image as above on your tablet? Then, let's check what to do next 👉🏾

Step 2: Place and Scan QR target

2.1 Place artificial feature magnets every ~ 3'-0 throughout the assembly.

You should receive the magnets along with the QR code target. The magnets will look like this:

Once all the circles have green checkmarks, you can place and scan the QR code as described on the next page.

2.3 Place the QR target

You need to draw a centerline on the material you are working on and place the QR target on the edge of the material with crosshairs aligned to the centerline.

There are 2 possible positions to work on the assembly:

2.4 Match the Tablet View (Hologram Orientation) with the Assembly on the Shop Floor

After selecting Auto-Fab and choosing a HoloLens, the Part Selector screen appears. Follow these steps to make sure that the tablet view matches the assembly orientation on the shop floor:

a. Part Selector: The part of the assembly in blue on the tablet is where the QR code will be loaded. To load the QR code onto a different part of the assembly, tap that part; it will turn blue.

b. The tablet always displays the top view of the assembly (birds eye view).

Use the three buttons at the bottom of the tablet screen to rotate the assembly within the tablet. Rotate the assembly to match the top view of the assembly on the shop floor.

c. Match the left side of the tablet view to the edge of the assembly you are standing at. The tablet always loads the QR code onto the left side in the tablet, so it’s important to rotate the assembly based on your standing position.

d. Tap Confirm in the top right corner once your tablet orientation matches the assembly on the shop floor.

• Tap on the magnifying icon to zoom into the QR marker placement.
• Use the joystick to make micro-adjustments to the QR code. Match the tablet view to look exactly the same as how the QR code is placed on the assembly.
• Keep the QR code close to the edge of the assembly.

Once the adjustments are complete, tap Confirm in the top right corner.

2.6 Scan the QR target

Next scan the QR code. Scanning the target is done the with the HoloLens. Please do it exactly as per the video above.

2.7 Scanning/pre-alignment issues

There are some issues that can appear if the QR-code is scanned incorrectly. There is an easy fix for all of them, so please go through all the cases below and check how you can fix the 3D model:

Step 3: Mapping the area

3.1 Start mapping

Once you scanned the QR target, there will be a prompt to map the area.

IMPORTANT: Do not leave the area of the QR target before you click on the Mapping button. If you want to move away from target, you have to start mapping the area first.

3.2 Mapping area

Your mapping area should be only 3 sides of the assembly - there is no need, nor it's efficient to map the whole assembly. Here are the examples of your working/mapping area:

While mapping the area, the camera is looking for the unique features of the area to mark and remember them.

It captures the initial data, so the system will remember its environment when you walk around - that's also the reason why you needed to put AF magnets before.

3.3 Finish mapping

Once mapping is done, click on "Finish":

And now it's time to actually align an assembly 👉

Step 4: Aligning an assembly

The alignment is done with the HoloLens, but with the tablet controls.

This is what you will see on the tablet:

There are certain rules that you need to follow while aligning an assembly.

4.1 If needed, rotate a 3D model of the assembly to match the real one using Center controls.

4.2 Always start with the side where you placed a QR code, and use Right-hand Controls for this.

4.3 After the side with the QR code is done, go to the opposite side and fix it using Left-hand controls.

Done with the first adjustments? Let's finish the alignment process

4.4 Last adjustments.

While working with the assembly, please remember that you are working with the perfect model within the FabStation and imperfect material.

IMPORTANT: it's fine if there is a small discrepancy in some places between the model and the material, but even this discrepancy should be no more than ±2-3 mm.

• You always start with 1 and continue as per the numbers sequence.
• In 1,3 you will be using right-hand controls, and with 2,4 - left hand.

While small imperfections (±4-5 mm discrepancy in some places) are fine, you need to look attentively for missing details or other deviations from the model as the tool is made to find the mistakes that can easily skip the eye.

Alignment shouldn't take much of your time. Very first alignment can take up to 10 minutes, but master with simple objects is that you can do it within 2 minutes or less.

And lastly, we recomment you to download and print this Cheat Sheet, as it may greatly help you during the alignment.

All good? Let's recap 💡

Recap

Since it's a technical and important part, we have created a small recap for you to sum up the most important points:

• Place a QR target exactly as per the image within the Step 2.2;
• Do not move away from the QR target/code until you start mapping the area;
• Map only one side of the area where you will be working;
• Expected time to align an assembly: 2 minutes. It means that you mastered it;
• Start with QR code side - right-hand controls. Opposite side - left hand;
• Download and use Cheat Sheet for alignment tips.

Task:

Try to align a couple of simple assemblies (i.e. a column or a beam) using this guide to improve your skills.

Check if all parts of the assembly are in place. It's fine if you won't reach 2 minutes time for each alignment.

Tests time!

You are almost done!~ Good luck

Perfect! You have done your first step in this amazing world of augmented reality 🎉🎉🎉

Time to get back to our old good non-augmented world.

Would you like to go through the Basic Tablet Alignment guide as well? (Please mind that it will have the same information as in this guide, except for the slight differences that are related to the alignment with the tablet only).
