Question 3

How to take your first scans with iMapper 1 and 2

Accepted Answer

Welcome to a step-by-step guide on how to take your first horizontal and vertical scans

For iMapper Racer 1 & 2 only.

If you have an iMapper Racer 3, go to these articles:

iMapper Racer 3 Starter Guide: quick on-boarding protocol How to take your first scans with iMapper Racer 3

| Pro tip! Charge your iMapper completely before using it.

iMapper will give you an idea of its charge with acustic signals when you turn it on: 1 beep: 3/3 charged 2 beeps: 2/3 charged **3 beeps: **1/3 charged 4 beeps: it needs charging

Step 1: Set up for a horizontal scan

Open the tripod making sure you have unfolded all necessary parts to their full lenghts. Then, adjust if necessary.
Remove the small plastic plate and attach iMapper's base directly to the tripod.
Ensure the tripod is leveled.

|| If walls are vertical (it’s not the case if the walls are out of plumb), the error due to a not perfect horizontality is not that important (+3mm if you are above the horizon line of 10 cm at 3m distance).

Step 2: Place the iMapper

Place iMapper in the first room you want to scan.
Make sure that for thi

Question 4

Export Data to File: from iMapper to AutoCAD with ease

Accepted Answer

Introduction

Welcome to our step-by-step guide on exporting files from iMapper for use in AutoCAD. This article is designed to assist both beginners and experienced users in smoothly transitioning their work between iMapper and AutoCAD. Whether you're working on detailed architectural plans, engineering drawings, or any project requiring precision and compatibility, this guide will ensure your workflow is seamless and efficient. We'll cover everything from selecting the right file format to troubleshooting common issues, ensuring a hassle-free export experience.

| Tip! Make sure you have done all necessary scans using iMapper. | If you're not sure how to get started with your first scans, check out this article: iMapper Starter: quick on-boarding protocol

iMapper to AutoCAD: Step-By-Step Guide

Step 1: Export data to file

Simply click on the Export button, select the DXF option and unit of measure you prefer working with. Point clouds, lines betwen the points, walls (that you can draw with the area tool) or iMapper positions can all be exported, you can choose to export them by ticking the relevant boxes.

You can export the point clouds under several layers if necessary (one layer per point cloud). To do this check the box “one layer per point cloud and area”.

Once you have all your setting

Question 5

How to manage pointclouds

Accepted Answer

Step 1 : Understand each pointclouds

Insert each scan by clicking on the purple + button in your ** Project files** layer panel (bottom left of your screen), then select the scans you want to view in your project and click Add.

Notice how some pointclouds will attach automatically, the automatic assembly will be successful if scans in adjacent rooms have enough points in common.

Learn more on this topic here:

How to take your first scans with iMapper (15 min)

Select and move each one of them by selecting it and dragging it around your workspace area.

| Pro tip! You can select each pointcloud by clicking on the iMapper target or by selecting the single scan in the Project files layer panel. Use the selection box by left clicking on your workspace and dragging your mouse over the pointclouds you want to select while holding the click.

Step 2: Viewing photos.

You can force the system to display the pictures of a specific pointcloud by selecting it.

Click on the **Panorama ** icon at the top right of the screen to show / hide photos. Select a pointcloud to view only the photos related to the selected pointcloud.

Step 3: Manage pointclouds

Question 6

Is it important that the iMapper is perfectly horizontal during a scan?

Accepted Answer

Achieving perfect levelness isn't always essential for precise measurements when using iMapper. A slight deviation, such as measuring 3 meters away with a 10 cm dip, introduces a minimal error—approximately 1.7 mm, which is often negligible.

This principle applies variably across different distances, demonstrating that minor inaccuracies can be acceptable depending on the context.

| a (cm) | b (cm) | c (cm) | error (cm) | | --- | --- | --- | | 300 | 10 | 300.2 | 0.2 = 2mm | | 500 | 10 | 500.1 | 01 = 1mm | | 1000 | 10 | 1000.0 | 0.0 |

| Tip: For a hands-on exploration, use this editable Google Sheet that allows you to input your own values while illustrating how certain deviations impact measurements.

Nonetheless, it's crucial to note that in specific scenarios, like measuring against a non-vertical surface in an attic, the error margin can significantly increase due to the added complexity of the sloped angle. This emphasizes the importance of understanding the impact of environmental factors on measurement accuracy in iMapper applications.
