Why BTLx ?

BTLx is a free standard that can be used for data exchange between different design software and between design software and machines.

BTLx is a modern standard based on xml and features an xml schema for the validation of BTLx files. BTLx is closely related to the classic BTL (ascii) format but offers significant improvements and simplifications.

BTLx includes a complete description of the format and all processings.
BTLx describes parts in a machine independent geometry format.
BTLx files can be viewed and checked with our free BTL viewer.

BTLx comes in two flavors, as xml text file (extension *.btlx) and as zip-compressed xml text file for minimum file size (extension *.btlz).
