moving and placing derived objects in part studio

how do I unlock and move a derived object inside a part studio?

    A derived feature will appear in the exact location it was modelled in so you must use transform to move it. If you transform by mate connector you have more control.

    Wow, that is a HUGE impediment to moving from solidworks to onshape if you've not always designed top-down. I hope I'm wrong, but it as though when I import a complex assembly and the OS assembly looks great and the part studio looks like a random bucket of parts, I have to reassemble  everything in it before I can recommence working on and adding to it top down?
    Part studio is great for top down designing, but there must be a way to get the old sw assemblies in there as assemblies.
    Surely, as one tab in os knows where the parts should be, a transform routine could be invoked to move the part studio bits to the same position? Even as a once only option.

    @rob_vork, The easiest way at present is to derive it, and use "Transform" to move it by known distances or possibly a "transform by mate connector"  to move it to a defined location.

    Transform

     

    transform in toolbar

    Transform adjusts a part's location and orientation in 3D space with the option to copy the part in place.

    OpenSteps
    1. Click transform icon.

    2. Select the method of moving the part (transform type):
      • Translate by line - Select an entity such as a part edge
      • Translate by distance - Specify a value and select an entity to indicate direction
      • Translate by XYZ - Specify axis values to move along or optionally, use the drag manipulator that appears to position the part along axis
      • Transform by mate connectors - Specify two mate connectors by which to reorient the placement of the part.
      • Rotate - Move the part about an axis specified by selecting an entity
      • Copy in place - Make a copy of the part at the same location; this creates a separate and independent part enabling you to:

        - Make changes to one part and use both to create different bodies during a later operation.

        - Make a copy of a part prior to a series of operations enabling you to reference the original state for ancillary operations.

        - Create multiple copies of a part in order to create multiple variants.

        If you need to create multiple copies of a part at once, use the Pattern feature with a distance of 0 (zero).

      • Scale uniformly - Scale a part by a specific factor and select a point to scale about; optionally copy the part
    3. Click green checkmark.

    @bill_rayner , When importing a CAD file, you have the following processing options:
    • Imported models are in 'Y Axis Up' coordinates - If the file was created in a system that orients with Y Axis Up, the models would by default be brought into Onshape (a Z axis up system) with a flipped coordinate system. Check this box to reorient the axis system to match Onshape and display the model with the coordinates you expect.
    • Import file to Part Studios only (flatten) - If the file is an assembly, or contains an assembly, you have the option to import it as only a Part Studio, by selecting the Flatten option. In this case, the assembly is flattened to a set of parts in a Part Studio. There will be duplicate parts created whenever a part is instanced more than once.

    flatten imported assemblies option

    The automatic processing happens only for files that Onshape can translate. All other files are simply imported into a tab.

    Note:- Check first box only (Second box must be uncheck) if you wanted all assembly part in one part studio.

    I'm afraid none of that helps: I still have to transform dozens or hundreds of parts in the part studio that imported with their with their origins coincident, that had previously been arranged in a SW assembly.

    The annoying thing is that the parts are perfectly assembled in the OS assembly, but effectively locked in a glass case, unable to be directly worked on. So, as all the data required to move the part studio parts to the same positions as in the assembly actually exists in the onshape file, why isn't there a "Replicate Assembly Part Positions" command in part studio.

    I would guess that most people paying their Onshape subscription now, and a long way into the future, will have legacy assemblies they want to import. And I suspect Onshape's import system is the only CAD system that destroys assemblies during import. Clearly the RAPP command should be a top priority.
