I have an assembly of a piston which can move up and down in a tube. Yet when I insert this assembly into a new assembly as a sub-assembly and try to change it from rigid to flexible I get the error message - "sub-assemblies with layout sketches must be kept rigid".
Seeing as I don't know what a layout sketch is I'm at a loss as to how to change the assembly to allow it to become flexible.
What version of SW are you using? Can you share the part so myself and others can take a look? I recreated a similar sub-assembly and was able to make flexible. With out seeing your part file its hard to figure a solution.
I'm on version 2008
Not as far as I know. There are reference sketches within some of the parts within the sub-assembly, but they don't affect the sub-assembly when it is just an assembly so I wouldn't have thought it would affect it later?
I don't know how to share the file.
I've redone the assembly and now it can be made flexible as a sub-assembly so I must have done something different 1st time.
Thanks guys.
When you look in your Feature Tree SolidWorks is pretty good about showing you references. You will have something like this -->X next to a sketch or feature if it has a broken reference for example. Look for these signs. You can also right click on a part or feature and show parent/child relationships or references. You have to be extremely careful when modeling parts within an assembly as well because if you do things like click on a face, you create a reference and a relation.
