Hello. Running SW 2017 SP2. I've started an Assembly, building a Lego kit (for fun & practice). The parts are Inventor .ipt files. When I try to insert a Component that I have inserted in a previous step I get the message "The selected file has already been imported". I'm fairly new to SW, I haven't gotten this message when building other Assemblies while inserting .sldprt Components. Using Copy with Mates would be more time consuming that Insert Component - I believe. Any advice please? Thank you!
