DXF Export Save the effort of manually transferring your hand-drawn sketches into CAD software—Solaflex lets you import created drawings directly into CAD programs with just a few clicks. Split into parts This premium feature displays the generated contour in detail. Individual parts to be processed can be shown separately and easily transferred to the raw material. The bill of materials can also be exported and sent as a PDF file. Custom PDF With the custom PDF feature, you can easily add, edit, and delete dimensions on your drawing. The dimensioned drawing can then be exported as a PDF document. Measurement Sheet Solaflex’s digital measurement sheet provides an innovative measuring method that simplifies standardized measurements, product specifications, and the complete collection of all relevant data. Whether using custom templates, direct data transfer, or seamless integration into existing ERP systems—the digital measurement sheet makes the entire process more efficient and error-free. Table Export and Templates Created tables can be saved as templates and recalled at any time. In addition, the tables can be exported as CSV files—either directly from the app or via MySolaflex. Additional Features: Drawing Mode Two basic modes are available for creating drawings: freeform mode and coordinate mode. Freeform mode is ideal for right-angled contours or rough surface capture, such as floor plans. Measuring in coordinate mode produces the most accurate results. In this mode, all contour points are defined by two coordinates, X and Y. This method also makes it easy to measure complex surfaces. More information can be found at www.solaflex.com. Table Mode In this mode, tables can be individually created, configured, and filled with measurement values and text. Calculator columns allow any type of arithmetic operation—for example, to directly include deductions or additions. Custom dropdown menus can also be created and selected from. Additionally, table rows can be freely numbered. Insert Cutouts Walls, floors, or ceilings often include installations such as sockets, pipes, or similar. The app allows you to insert and configure various types of cutouts as desired. Freeze Outline To ensure smooth installation of the measured object, the "Freeze Contour" function can be used. After freezing, installation tolerances or overhangs can be easily added to the drawing. Move Center cross This function allows the crosshairs to be moved into inaccessible areas. Measurements can then be continued from the new position. Generate PDF Drawings can also be exported and sent as PDF files. Project and Drawing Management Drawings and tables can be grouped into project folders. Photos and Notes Photos and notes can be attached. These attachments are automatically included in the PDF.
KRL SmartBox
Read full descriptionHide full description
The KRL Smartbox app can be used to retrieve measurement results from the KRL Smartbox via Bluetooth. The measurement results can be supplemented with further information and then exported as a PDF. Using the KRL SmartBox makes it possible to measure the corresponding relative humidity of mineral screeds. Changes in the temperature of the sample can influence the measurement of the humidity above it. During measurements with the KRL method at a temperature of 20°C ±5 °C, the expected maximum humidity deviation is ±2% relative humidity.
