Topology Study : How to Model Threaded Nuts

hello this is Thomas in this tutorial I'm going to show you how to model a nut with the thread inside so it can be a tricky part because the thread itself is often subject to some topology Distortion especially in this area at the beginning of the thread so I'm going to show you my approach to make it look perfect so let's get started alright so let's create a cylinder with 32 sides go into edit mode with pressing tab three select this face inset you can raise it a little bit grow the selection by hitting Ctrl Plus on your numpad invert it by pressing Ctrl I and delete now go to top view we are going to draw the shape of the nut with the help of the knife tool you can find it here or with the the shortcut shift K so draw some straight lines like so all right press enter select the center face press Ctrl plus to grow the selection invert it and delete we can insert this face once more and delete it this is what we are left with so now we are going to give the nut some thickness so press shift alt left click on the border e z and sz0 to make it flat with the help of the snapping tool right here or by pressing shift tab we are going to select this border e z and snap at the bottom select this border right click and Bridge so this is the base shape of the nut now let's add some bevels so you can go to select select sharp edges and Ctrl V and if you go too far as you can see the bevels are intersecting so you can press C to clump and now I can't go any further but I don't want them to to get too close so I am going to make them like that add a bunch of rows here raising off add one here and one here okay so now let's take care of the inside so let's press three to go to face mode shift alt left click and press P to separate by selection so now there are two different objects shift H to isolate it okay let's add some edges now here I'm going to split this center edge by pressing alt m and split Faces by edges I selected I press proportional editing with connected only and I can do gz and move everything up until the vertices aligns so I'm going to press a to select everything 1 M and merge by distance so now to create that pattern I am going to select this Edge and this Edge F to fill to the same at the top okay I disable uh proportional editing I select this border e z SC sc0 to make it flat let's do the same at the bottom okay and now I'm going to select everything but this Edge and this Edge I add a bevel with a with one segment like so I pressed three to con to convert into faces I deselect this small triangle and this one as well and what I can do now is extrude along the normals so I press e right click and and press alt s so I'm going to to extrude outwards so like so we can delete these two triangles I select this Edge and this Edge GG to slide them away connect these two vertices and do the same at the top GG and boom and what I can do now is to add a loop here so this triangle is not a triangle anymore because it has four vertices I'm going to sharpen the the screw the the screw pattern by selecting this Loop and press GG towards the bottom and do the same with this one towards the top right like this okay and if I press right click Shades moves and add a subdivision surface modifier as we can see there are no distortions what we can do now is unhide everything and adjust the height of the the interior part so first I am going to do origin origin to Geometry as Z like so and I'm going to to to make the two objects uh one object so I select everything press Ctrl J and I am going to uh bridge this little Gap with right click bridge at Roop and I can delete this one and do the same at the bottom Bridge and delete and that's it we have our perfect um nut with no shading issue as you can see it's perfect if you found this video useful give it a thumbs up and please consider subscribing it's free and you can always change your mind I will see you in the next one bye
