    I'm talking about the shape circled in red. It's not as easy as it seems at first glance. I tried modeling it, but I don't think my solution is the best. I used a mirror modifier and a subdivision modifier, but it still looks off.

    You can tell it's supposed to match the reference shape, but it's not quite right. I know I'm missing the two cylindrical shapes on the sides, but that’s not the only issue. The proportions don't seem to match either. Am I imagining things?

    I would really appreciate some feedback. How would you approach modeling this shape?

    You just need more vertical edges on the cylinder to start out with. When you're doing cutouts and panel lines on cylinders you need a lot of geo to establish the curvature first, then make your cuts.

    I'd start by blocking out each connection and bolt hole, and work from those cylinders out. It is just soft subdiv like connections between those different points.

    Yes, because it is a circle and if you make another edge, you will get artifacts on the circle.

    Also might help to check out other sofa models, like this one from Polyhaven.

    Note this is lowpoly modeling technique, not good for subdivision, but great for in-game use.

    The Polyhaven models are all CC0 and fully downloadable to examine:
    https://polyhaven.com/a/sofa_03

    I used that model recently to up-rez it for the glTF Sample Assets repo, https://github.com/KhronosGroup/glTF-Sample-Assets/tree/main/Models/SheenWoodLeatherSofa#screenshot
    And a live demo of it:

    Hi Guys,
    I am modelling a complex object but facing some challenges.Can someone please help me with this.
    Thank you for your time 
    Problems to solve 
    1.topology
    2.pinches 


    you want the spiral shape to continue on the top and don't try to solve the additional controlloops on the slope if you don't have to



    The pipeline I work in has a QC check that will reject the model if ngons are left out. I think I fixed it by merging the control verts and target welding it to the bottom edge. 

    Thanks for the help. Lol, I forgot to say this 6 years ago 😅

    Your model looks a lot cleaner! Yeah the biggest issue I had were the armrests. Getting the right shape and making them naturally connect to the bottom of the sofa, seems difficult. Im not sure what an easy way to go about it would be. Thanks for the example

    You either need enough edge loops around that cylinder to match the number of bumps around the lens, or you need to make a separate piece of geo with enough loops.

    In blender one can use the inset tool to inset  ( shortcut I ) the rectangles individually ( shortcut I again )  while draggin with the  mouse and control the depth ( Ctrl-drag mouse ) ( or extrusion) like so (the cylinder has 64 vertices and the middle ring has 128). In other software there is properly somethign simialr (maybe named differently) :

    hello everyone, i m not an expert in modeling so the problem is i was following a written tutorial ( no graphics just 2-3 images ) and after everything is done i applied Subdivision Surface Modifier Level 2 and also shade smooth by angle, it came out decent and i am satisfied with the results, but the front part of the Model is Just making the whole experience terrible and waste. i am kind of stuck here. 
    I know there are not many loops on that region ( as you can see in the photos) but inserting Edge Loops is changing the shape ( by changing the shape i mean the model look sharp) of "The Front " part of the model and i want it smooth. so is there any other way to make just the front part look smooth without adding level 3 of subdivision surface modifier which adds extra geometry or without adding extra edge loops on whole model.

    i saw tutorials where people use techniques like rerouting, recreating, reducing, redirecting edge loops in topology and create 4 edges with 2 edges. i don't really understand how to apply that here. those were basically reduction of edge in topology tutorials and i hope it can be done vice versa. 

    Thank You in Advance    

    File Here - FILE ( Low poly 3d Model, jagged edge issue, topology, Modeling )   


    THE Problem - Jagged edges, subdivision level 2 applied, and shade smooth but front part is not so smooth. as you can see in the subdivision panel


    * Subdivision level 3 applied and the smoothness is decent / good, i want this kind of smoothness but subdivision level 3 added extra unnecessary geometry. 



    *The result i wanted, i saw people using methods like rerouting / recreating / redirecting edges to create 4 edges with 2 in topology. obviously i don't know how to do this here.

    Maybe just do what you yourself suggested in you file with the annotate tool ?? Select wanted edges and subdivide and merging tris to quads ( with unchanged annotations..) like so;

    Especially, parts of bevel, edges are complicated.
    And  both side are little bid extruded. these are integrated with a pillar

    Wondering how to do the following drill, which has very particular angles for its helix:

    My best attempt was to model it flat, then use 2 SimpleDeform modifiers to make it cylindrical and later taper it. This attempt however doesn't match the general angle of the Target's spirals.

    I also tried using Archemedian Curve spirals but, I have even less control if I use those imo. 

    How would you go about doing this? 

    Attaching the .blend scene to this post if its helpful  :)

    @okidoki Thanks for your input! Right, that's the method I was referring to when I said I tried using Archemedian Curve spirals. The curve created differs from the goal, though obviously those are sketch lines and some variation in the final thing is to be expected...

    ...Maybe I'm being too hopeful with this and just gotta bruteforce it :#

    It's based on a very stylized concept I cant share - it isn't meant to go for a realistic look for sure. I think the Target example that's provided gives an accurate idea of the goal here though. Just getting the general loop flow to be accurate would be enough, no need to start modeling things.

    Understood. Here’s my attempt at it so far. I tried to keep it as procedural as possible. Hopefully it will inspire someone to find a simpler method, but it should be workable as is. Unfortunately, I’m a 3ds Max user, but I hope this provides some ideas on how to apply it in Blender.

    @hanabirano That looks clean! I think it's similar to my attempt though, albeit with a cleaner finish. How easy is it to alter the angle of the spirals if you wished for it? I wonder how it'd match with the reference spirals.

    @okidoki "A triangle extruded, tappered, vertical sub divided, rotatedvia proportional editing, subdivided in edit mode, "edges" beveled:" The end result looks like a better approach than the last one you showed, thank you for sharing. It's a bit hard to follow the initial steps though, could you maybe elaborate with pics or a short vid of the initial steps you describe?

     I used a triangle because you want this three edges; you also could use a multitude of three and select the three edges later to bevel and resise them along X/Y. (Oh i misses this in the following image :wink: )

    Its relatively easy, you just have to tweak the height of the helix cylinder (looking better at your reference it seems to me that the gradient and scale step for the swirls is not needed so I removed it):

    Individual cylinders for each strand, then for the low poly you can either retopo each strand individually (simply going into edit mode and deleting edges that go alongside the cylinder), unwrap the low poly strands saving some space in the UV map for each individual strand and bake each high poly strand to their respective low poly versions. Or the other option is to retopo them together by creating a mesh that wraps around the whole chunk of high poly strands and then baking all the strands together with the new mesh.

    Update: I remembered that the handguard comes in two shells put together, which makes it easier.


    Hi friends
    I'm modeling the handguard of the M16A1. But I'm stuck on making these vent holes.
    The SubD modifier makes the sides of the hole bulge, it should be flat here.
    I've tried a couple of ways but they all leave pinching around the holes. (Another method will leaves two parallel pinching lines across the handguard



    And the shrink-wrap modifier works but creates new problems. I tried setting the vertex group in the modifier, but it still seems to override the bevels.
    Is there a better topology? Or how to keep the bevels under the influence of the shrinkwrap modifier?

    This might depend how you models this; while retrying this i did this with insetting the face and afterwards adjusting them to that oval shape. Whether if you simple scale the outer edges inwards (not on surface along Y in you blender screnshot) or even vertex slid them on the diagonal to stay on the original surface, when doing an additional inset and then extrude downwards..

    But  the loop at the "hole edge come up a little" when using subdiv. So this might be opimized by "simply" moving the control loops i bit downward.. (left original , right pushed down)

    I probably overthinking it sometimes, moving points and edges are also a part of 3d modeling.
