Part online measurement method based on BLUMFormControl software in plug-in-free state

The invention discloses a part online measurement method based on a BLUMFormControl software plug-in-free state, and belongs to the technical field of part online measurement. Comprising the following steps: part data extraction and data analysis: after part data extraction and opening a to-be-measured part digital model in CATIA, creating a geometric figure set, establishing a world coordinate system and a part processing coordinate system, importing the to-be-detected part digital model, converting the coordinate system of the part digital model from an aircraft coordinate system to the world coordinate system, and analyzing the part data; the method comprises the following steps of: after the conversion of a part digital-analog coordinate system is completed, saving the format as igs suffix, obtaining a converted part digital-analog, after the conversion of the part digital-analog coordinate system is completed, opening the converted part digital-analog in the FormControl, compiling a measurement position
