Perhaps I’m not cut out for this whole modeling thing! I can get this modeled in poly software, but I need polysurfaces in Rhino and it’s really kicking my butt.
This is a hammer for an antique pistol and I can’t seem to figure out how to blend the two. The extrusion is flat and I think a simple filleted edge would suffice, but I can’t figure out how to merge it smoothly with the cylindrical sweep.
Looks like a kitchen faucet, which I feel like is something I couldn’t model even if Delta had a gun to my head!
What exactly do you mean with “blend”? Fillets? Transition surfaces? A square-to-circular transition? Do you have sketches or mock-up photos of what you want this to look like?
I’m not exactly sure if I’m using the right terminology. Here is a photo of the part, but I’ve put some colored lines over it to demonstrate what I’m trying to explain. The red part is mostly a flat extrusion, in which I want to bevel the edges a bit. So when the thumb goes over the top part of the hammer it’s flatter and easier to pull back. And the blue part is a round pipe like shape, I initially made with just a sweep. The yellow part where the two converge.
These could be just an extrusion and a sweep with a union, but the problem is they’re the same width, so the sides are flat.
I hope that makes sense! Also, it’s solely just a display replica, no moving parts or any functioning parts haha.
That whole thing looks rater soft though, the top spike seems like a “wavy cone”, judging from the crude photo’s highlights, unlike a blocky 2D extrusion. If all you have is that low-res 2D scan from a book, probably SubD should do the job nicely.
Yeah, I was thinking that was probably what I should do. But, I’ve never used any of the subd tools in Rhino yet. Also, do they interface well with Polysurfaces? For example, I will need to make a slightly larger outer wall to do a difference with the part this attaches to, so I can have a bit of tolerance to snap the two peices together.
splitting the pipe shape into 4 surfaces then blendsrf to the square element.. you’d need to create some space between the pieces in order to have room for the blend to happen, but as Lagom said, I think that will not yield the shape you are looking for…
Hi @Jordan_Miller
Here’s @theoutside’s “paper doll” video, which is a great introduction to this type of modeling. Sub-D’s aren’t hard (but takes a little getting used to), especially if it doesn’t need to be exact to 0.001mm. Here’s my two-minute try. I’m sure someone more proficient could make a better layout, but maybe you can use it as a starting point The flat face is the original face layout prior to extruding/adjusting. Notice that I’ve used SubDCrease to create the edges at the rear low of the hammer.
The picture you posted doesn’t show the whole shape. Another view would be nice.
Here is how I would model this percussion hammer. hammer.3dm (549.4 KB)
