Details
Exported multiple solids from another CAD program as one STEP file, then opened the STEP file as a .par file in Solid Edge. All of the closed surfaces are interpreted as one Part Copy. Is there any way to have Solid Edge preserve the different bodies and open this file with distinct multiple design bodies rather than merging them into one Part Copy?
Solution
In your STEP import file selection dialog, click the Options button after selecting STP file and uncheck the option to Boolean Solids.
Also in the Solid Edge Preferences Translators folder there is a file called STEP.ini which controls step translation with a parameter called 'Import Multiple Bodies As Single Part file' that you could check and change to OFF (default setting is ON).
