Hi FDP and Michael,

I use a similar program set MOI > RHINO > SOLIDWORKS

I primarily use MOI for conceptualization the sketch freedom and 3d roughing leaves SOLIDWORKS and RHINO in the dust. Once I start to firm up a design I use RHINO and instances to form my assembly based on MOI parts. If I have a MOI assembly that needs multi parts instanced I do that in RHINO. I then via STP export move into SOLIDWORKS for major assemblies and Drawing Sets. I find the workflow works well instancing in MOI would mean no RHINO and move straight into SOLIDWORKS for major assemblies and Drawing Sheets. The Solidworks DRAWING SHEETS are some of the best documentation production tools and hard to beat. I agree with Michael keeping the simplicity of MOI is the upmost importance to its workflow speed - a few enhancements welcome but for a ZEN modeler like MOI to ever be like SOLIDWORKS would in effect loose its ZEN.

Look forward to V4 with grouping and instancing.

All the best
