How do I make the stock part of this rifle?

    I think you'll need to make your document public for us to see it. It seems like Loft is the tool you're looking for.

    learn surface modeling techniques. You won’t likely get it to look right using typical extrudes lofts fillets etc.

    Personally, i would start by removing the fillet prior to the straight hand grip, and focus the grip and the stock as two different jobs.

    There are plenty of nerf 3d model .steps i would recommend you use for shape reference! I myself am in the nerf hobby and have held the SLAB (Silly's Lever Action Blaster). The length of pull would be much shorter on the .step, aaaand sadly .steps don't include the timeline, HOWEVER! you can probably get a feel for what angle is right for you, what shape to make the length (i.e. the stock won't stay rectangular, it'll form a sort of cylinder/rounded shape when you look at the buttplate)

    Also, don't trace the fillets, try to add them later, by instead putting points at the end of each line, Fix them, then make Lines that are Intersecting with the fixed tracepoints, but the ends of the lines intersect with eachother at each angle! like so:

    Overall recommendation:

    Try to model your own buttstock after tracing this one, i personally practised some modelling by using a dummy grip with a trigger, (Maybe by using play-dough or clay, etc. Just make sure you can imagine yourself comfortably pressing the trigger) and then sticking/taping a ruler to form the length, and then taping another tiny ruler to make a T to measure the ideal 'comb' for the buttstock!

    References you can possibly use! (Heh… totally not an excuse for you to look at hobby nerf… teehee)

    (Also the SLARP, an edit mimicking a winchester contract 1895, i think has a longer length of pull, so maybe reference that!)

    ^ these are pretty good to look at, this following video might give you a better idea of scale:

    pls ask any questions you feel like needing :3

    This seems like a pretty simple stock. So I doubt you need too crazy of surface modeling. Just sketch a profile at the start of the stock, and a profile at the end, then Loft between them. You can then use extrude to shape up the butt of the stock, then Fillet the remaining sharp edges.

    The best way to learn these techniques will be the Onshape Learning Pathways. Specifically the Advanced Part and Surfacing Design pathway.
