Demoted framemembers get forced grounded?

[cahoe]

I made a construction with the frame generator from a single sketch.

I managed to select a handfull of framemembers an demote them to a new subassembly.

Now it turns up Grounded with the grounded options grayed out?

Do I have to delete it and replace it?

Seems odd?

Possibly because they are still controlled by the sketch in your FG assembly, and therefore can only move if the sketch moves?  I've never played with demoting members of a frame like that, I usually just build them independently and control location with constraints at the top level.

It is not really odd if you think about the way FG works.  You create a sketch and insert that into an assembly (which is already a sub-assembly in most cases) that using that sketch with in the assembly you place your frame pieces.

It makes sense to me why it is greyed out.  It is still tied back to your orginal assembly.

I have to ask, why are you needing to demote frame generated parts?  To me it is easier and less confusing to just create an new sketch and new assembly.

Yah, if you want to be able to move things around, you need to insert your frame generated assemblies and subassemblies into another assembly. You can build them all in one assembly, which I always label as master, but you cannot move them around in that assembly as they are tied to the sketches and skeletons. Start a new assembly and insrt all your subassemblies into it, then you can move them where you please without woring about messing up your master. And as I found out the hard way, NEVER unground the original sketch used to make the parts 🙂

I always see mention of not demoting parts, but I have never made a FG assembly without doing that. The original I leave as master, then demote all parts into their prospective subassemblies, makes such a smooth workflow in my opinion.

Thanks guys... solid advice!

Cadmanto.. your right.. Just have to wrap my head around the inventor way
