I inserted a part into an assembly of 3 other parts and I can't move the new part. I see on the forum that you should go to component properties and changed to "Solve as Flexible" but it won't allow me to change the setting. Suggestions?
Not sure if this is your issue? If any parts in feature tree has an (f) the part is "fixed", right click over part and select 'float'. It is best practice to keep (one part) the first part fixed.
Welcome to the forum. "Solve as Flexible" is for sub-assemblies (an Assembly inserted into another Assembly), not Parts. If this is a Part, as you said above, what type of movement are you expecting?
The part is either Fixed in space or mated such that it can't move.
