Includes all of the commands to create a free-hand design of the various significant elements in a survey:
Corner (Coming soon...)
Projections (Coming soon...)
Manually add the measurements of a selected element. If you select more than one element, these measurements won’t be added to any of the selected elements. Moreover, if you are using a Disto laser (distance) meter, you don’t have to use the “Measure” function, though you do have to connect the meter with your device, using “Settings” menu.
The “Validate” command is at the core of Sharpy Survey’s technology. Once you select it, the WithHands Algorithm automatically creates the graphic restitution, verifying whether the measurements you input are sufficient to find a solution that corresponds with reality. If you’ve forgotten one or more measurements, the restitution will be interrupted and a graphic indicator will appear, showing you where measurements are missing and/or incorrect.
At this point, you input the missing or incorrect information. Only then will you be able to resume the validation.
Sharpy Survey has a +/- 1 cm margin of error, and the restitution almost always varies slightly from the original measurements:
- measurements that fall within the margin of error will appear in green
- measurements that fall outside the margin of error will appear in red
In both cases, the level of deviation is also indicated.
Allows you to add doors and windows.
Among the different types you can can insert: single doors, double doors, sliding doors and gates, as well as single, double, and triple windows and window-doors. Once you choose the block where you want to insert a door or window, you input its size and its distance from one of the vertices.
Consists of three different types of information: quotas, heights and text labels. You select the “Text” command, then you indicate the point where you want to insert the information, and finally, you input the information on the corresponding form.
Links two rooms or groups of rooms that share a common door: you select the common door and insert the measurements of the wall’s thickness in the corresponding the door frame.
What good does it do if I can still work on a semi-hidden path?
Deletes all the elements you select at any given moment.
Allows you to connect a laser distance meter via Bluetooth. Inside the “Bluetooth” folder, you’ll see a list of all the available devices. Below the settings icon is a switch icon which enables or disables the Bluetooth connection.
Undo & Redo
How can you live without this function?
The following is a step-by-step guide to performing a survey from start to finish.
Once you open the Sharpy Survey app, you’ll see the work screen, allowing you to immediately start your survey.
At this point, you create an approximate description of the geometry of the environment you’re surveying. The sketch doesn’t have to be to scale, but it should contain all of the elements that make up the room.
Select the “Sketch” command and draw the perimeter. On the lower right of your screen, there’s a reference scale (one meter), which gives you an idea of what the size of the sketch should be. However, you don’t have to rely on the reference scale -- it simply helps you create a sketch and a subsequent restitution that’s more or less the same size.
You can take the measurements of a selected segment in two ways:
Select the “Measure” command and manually insert the numeric data obtained,using classical instruments like a swivel meter.
Use a Leica laser meter with a Bluetooth connection. (Go to the “Settings” menu to connect the device.) The data is added automatically as you take the measurements.
4. Additional Features of the Survey Geometry
Sharpy Survey also allows you to add parametric features to the survey elements: 90° angles and aligned edges. You can select both by first selecting the related vertices (in the case of a 90° angle) or segments (in the case of aligned edges).
Set/Unset as 90°: Despite the difficulties of confirming right angles on site, we developed this function to give you the ability to perform a “simplified” survey.
Procedure: Select one or more vertices you want to designate as a right angle, then double tap the screen and select the command: the vertex/vertices where you want to assign the 90° angle will be indicated with a red right angle symbol. In addition, the distance between the first and second vertices will be calculated as the hypotenuse of a right triangle and will be verified during the validation phase, with no further measurements needed.
Repeating the same sequence on a previously designated 90° angle will disable this feature.
Select the vertex/vertices, then double tap the “Set/Unset as 90°” command
The red right angle symbol will appear on the vertex/vertices, as well its related
Align Edges: The alignment of edges is a fundamental ingredient in an accurate survey, allowing you to reduce the number of diagonals necessary to obtain a precise validation of the environment you’re surveying.
Procedure: Select one or more edges you want to align. Double tap the screen and select the “Align Edges” command: the selected edges will be marked with a capital letter.
Repeating this sequence on a previously aligned edge will disable this feature
Select the edge, then double tap the screen in order to set the “Align Edges” command
In the center of the aligned edges, a capital letter will appear, which corresponds to all of the edges lined up with one another
Sharpy Survey’s “Validation” command allows you to obtain an immediate restitution of the environment you’ve surveyed using the preceding commands.
Procedure: Select the sketch and select the “Validate” command.
Sharpy Survey will generate, if possible, a diagram of the surveyed environment, calculated according to the data you inserted. Measurements that fall within the +/- 1 cm margin of error will be indicated in green. Measurements that fall outside the +/- 1 cm margin of error will appear in red. In brackets is a delta which represents the discrepancies in the measurements. In some cases, the “Validate” command, which uses the WithHands Algorithm, may not be able to arrive at a unique solution because it doesn’t have a suitable data set, e.g. perhaps an edge measurement is missing, or the number of diagonals is insufficient. In the first case, Sharpy Survey will mark in red the edge(s) where measurements are missing. In the second case, Sharpy Survey will generate a prompt, indicating that a larger number of diagonals is needed.
Note: In order to obtain the restitution of any geometric figure, you need
the measurements of all the corresponding edges and a number of diagonals equal to the number of edges minus three. The number of measurements will decrease if you insert parametric data (e.g. one or more aligned edges or right angles).
Correct environment restitution
Environment restitution in which an edge(s) is highlighted because it exceeds the margin of error
Environment restitution is not possible because the measurement of an edge(s) is missing
Once the environment’s geometry is defined, you can proceed with inserting the openings and the “entry points,” i.e. doors and windows.
Sharpy Survey doesn’t contain an unlimited number of objects in its library, but it allows you to describe the features of the elements you want to insert in the survey. Once the DXF file is imported in AutoCAD, it’s up to you to eventually replace doors and windows with more suitable objects, using the “Replace the Object” command.
Select the area where you want to insert a door, then click on the “Insert” command (Fig. 1). Choose the “Door” command (Fig. 2), then the door typology, from a point of view within the room (Fig. 3). Then insert the measurements (manually or via Bluetooth) and the distance in relation to a vertex (Fig. 4). After granting its ok, Sharpy will ask you to indicate which vertex is the reference point for the opening you want to insert (Fig. 5). In the figure 6 you can see the opening inserted in the planimetry.
The procedure is the same as for doors, but it requires additional parameters: you need to specify whether you want to insert a window or a door-window, as well as the thickness of the wall surrounding the window.
You can also specify whether the panels differ from one other by inputting the measurements of each panel (Fig. 7). The figures below show a window inserted in the planimetry (Fig. 8).
The “Link” command allows you connect two rooms that share a common point of entry, arranging them correctly in relation to one another by lining them up with the shared door, while taking into account the thickness of the doorframe.
It’s important to remember that it’s only possible to link two rooms if the shared doors have the exact same dimensions and the same type of opening.
For example, if in Room A, the door is push-left, in Room B it should be pull-right.
Procedure: Select the doors that will connect the rooms (once selected they will be green). Then click on the “Link” command (Fig. 9). A dialogue box will appear, and you can input the wall’s thickness, as well as indicate whether the rooms are side by side, or one inside the other (Fig. 10). Click “OK”, and Sharpy Survey will arrange the two rooms according to the measurements you entered (Fig. 11).
Sharpy Survey allows you to insert quotes, heights and text labels. Click on “Text,” and then select the type of information you want to insert. After that, choose the point where you want to insert the text, click on that point, and fill out the form.
If you want to modify the information, just click on the text, and the corresponding form will show up. You can also modify the font and the size of text labels.
The “Layer” command is currently limited to allowing you to move a selected object to the first or second floor.
The “Settings” command allows you to access the Bluetooth dialogue window.
When you turn on a laser meter with a Bluetooth connection, it will appear as an available device in the Bluetooth list. Simply selecting the device connects it with Sharpy Survey. Remember to turn on the switch in the main toolbar below the “Settings” icon (by moving it to the right).
Once you complete your measurements, you can turn off the Bluetooth connection in order to save energy (by moving the switch to the left).

13. Other Double Tap commands
Another command available using the double tap function is the “Unlink” command, which separates two or more previously linked rooms.
Once you complete your survey, you can export it in DXF format. You can find the
“File Export” command in the “Home” section, as well as other commands for managing your files. Once you select the “File Export” command, a form will appear, requesting that you enter your email address in order to receive the DXF file verified by the Sharpy Survey server.
15. Other “Home” commands
Under “Home” menu, in addition to the “File Export” command mentioned above, you’ll find the following options:
The first three options are self-explanatory. The “Apple Store” option functions as a link, allowing you to manage your Sharpy Survey subscription.
