I open and use the .step file exported from eyeshot. The exported .step file seems to change the property information as shown below.
Example:
FILE_DESCRIPTION(('STEP AP214'),'1');
-> FILE_DESCRIPTION(('STEP AP203'),'2;1');
The reason I inquired about the above problem is that the specific functions that use the file became slower as the step file was changed.
The slowed feature is collisiondetection, a task that used to take 1 minute was not completed after an hour.
I wrote a question because the above problem was seen as a problem with the version changed during the export process.
