Orgadata LogiKal is a Microsoft Windows application from Orgadata used for the design, calculation and planning of window, door and facade projects. A BK1 file is part of this application's data.
The file uses a LogiKal-specific format and may contain information required by the application for a project or another internal LogiKal operation. Its exact contents depend on how LogiKal created and uses the file.
BK1 is not a general-purpose interchange format, so the file should be handled with a compatible version of LogiKal.
Open the file on Microsoft Windows with Orgadata LogiKal. If the file is associated with LogiKal, double-click it; otherwise, start LogiKal and use the application's file-opening or import function, if available.
A BK1 file may depend on other LogiKal data or on the LogiKal version that created it. If LogiKal does not recognise the file, keep its original filename and location and contact the person or organisation that supplied it.
Open the file in LogiKal and use the application's export, report or project-saving features if a different format is required.
Because BK1 is application-specific data, exporting from LogiKal may preserve only the information supported by the selected output format.
