We have flexible components on a pcb. These parts/assemblies are not showing up in the model tree with the flexible icon (with the spring in it) after idf import nor is asked for flexibility during import. So the parts have to be searched and the flexibility has to be assigned (via File / Prepare ... or RMB ...)
When assembling them manual (via GUI), then the question for flexibility pops up. Why not during the import and why are they treated like having denied the flexibility?
Attached movie was taken during a tech support session. It first shows the result of an already changed assembly and then the process of import and changing manually. The idf in this case was stripped down to contain only two parts.
