Hi there,
when the server is not busy importing and then inserting a STEP file into a Fusion design is a matter of 2 3 minutes based on upload and converting time. However if I have multiple files to do that wait time during a busy day is simply not acceptable at all.
Fusion tool 4 minutes to upload and make a simple DWG drawing accessible.
I think while the upload tool can have its benefit you really need to allow us Designers to load any data right into a Fusion file without the upload wait time.
