Kitchen sink 3d modeling

Hello!
I have great difficulty modeling in 3Ds Max. I repeat as a parrot other's tutorials, but when I try to make a model that I need, I immediately block. I already wrote many times here on the forum and I was helped all the time, but I still can not understand the basic principles of modeling.
Following Alekh's example - "Do not be naughty and wait for you to be shown and taught, and take and do, showing others what you are doing."

I decided to describe the sequence of my steps when modeling a shell, which later can become a tutorial here on the site. This is how the guys from Renderstuff decide.

1. Prepared 3 types of shell in Photoshop'e and inserted them into the diffusion of 3 materials. Then he built the dimensions with the sizes indicated in the PDF and moved them to the point 0,0,0 of the scene. Applied material to these plains:


2. I drew a rectangle of the recess of the shell with dimensions 413x228 mm, lines centered on the point 0,0,0 of the scene (thanks to Usco for the lesson of creating the rosette!):


3. Then I selected all vertices of the polygon and applied Fillet with a value of 50 mm:


4. Apply the Edit Poly modifier to the rectangle:


5. Returned to the initial line and selected the segment, then made an Outline with a value of 8 mm (I keep track of the numbers of the vertexes - thanks to Gus_ann for the help):


6. Did the Detach second segment:


7. I return to the first poly, I highlight Border and with Shift pressing I do Extrude on 102 on the axes:


8. Then I switch to a top view and adjust the vertexes to the second spline, and delete it (someone will say: "Well, you, Vasya", but if you have another way ... advise):



9. I select the central polygon and I do Extrude to -148 mm (in the form on the left 157-9 = 148mm) and delete it:



10. I create a spline on the dimensions of the shell in the view from above and make the Outline 25 mm. I apply Fillet to the internal spline at 20 mm and outer - 5 mm:


11. Again, I manually adjust the vertexes of the first poly to the new spline (and again I hear friendly cries of "Well, you, Vasya"):



12. I do an Extrude Border Main Poly on 9 mm:



13. Then again manually adjust the vertexes to the next spline ("Eh, Vasya ... Vasya"):



14. Again select the Border and with the Shift clamped do Extrude and connect the vertexes with the last spline of the overall dimensions of the shell (and then I thought it might make sense to use the Symmetry modifier, but alas late):



15. Let's cut the faces for TurboSmooth:




16. Let's go to the left view and cut the faces by fitting them to Scale and Move to the contour of the shell:



17. On the front view I remove half the shell and adjust the vertexes under the contour of the shell and then apply the Symmetry modifier:



18. Here is the result:



19. Draw a circle with a diameter of 74 mm and pull together all the vertices for the stitch:



20. Here is the final result (you can use the Shell modifier):




To be continued ... just do not know how to make springs and bolts with screws.

I will be grateful for any comments and advice.

Hello! To be honest, I have a good base for modeling and my wip pursues other objectives, there is likely honing modeling and work on the Pipeline "from the master model to the game model" Although, in general, do you think is correct, theory without practice will not give result. But it would be better you have set myself the task: "to do so and so ', so less likely to get out of the task. According to the sink ... I do not quite understand why so many hand-pulling points🙂 Why not do the same thing from some primitive? For example, instead of working with a spline, you can start with a plane and use a couple of tools: chamfer, extrude, insert, perform all the same manipulations with the object. Add to this move and scale - here and obtain the necessary form. Here, even the symmetry is not necessary 🙂

Hello, Aleh! Thanks for the comment. My main problem is that I'm constantly working with AutoCAD'om and Revit'om and 3ds Max - this is just a hobby for the soul. Well, I like to work in 3ds Max and all here and spend their free time in the modeling Max'e. The task "to do so and so" I set myself - the model should be a reference to the millimeter to a millimeter. Therefore, all these dances with pulling points and AutoCAD'e I would do so. You're right, you can use: chamfer, extrude, insert, but did not catch like. I can not understand how to use these tools to attain an accuracy to the millimeter. Thanks again!

I would have done it in AutoCAD using Boolean operations🙂 only there, as far as I know, has not turned out to flatten: | And so, in general, the accuracy of a millimeter almost anywhere and no one needs, and if it is necessary to you personally, then selecting any of the instrument me through the options (extrude: options, etc.) you will see the units, they will either you installed in the system, or a percentage of them. If desired, you can get accuracy to 0.01 mm

In AutoCAD'e can use 3dface, which is a primitive analogue Max'a polygons. Yes, I know that kazhny modifier have the opportunity to ask one, but I do not know how such chamfer'om control the radius of curvature shell. Yes, in principle, maybe you're right, no one really do not need such precision. I important to understand how others would come to the construction of a shell, and if my grid is correct.

Ilya on rounding in sabdivizhene usually enough 3 + 2 vertices already on level ground to maintain an even line. You've got 8 pieces on the corners of the sink bowl, and on a flat plot very personal. It is not too late to fix😉

Max, do you mean spline or poly?

Ilya, no matter what method you create a grid turbosmut. In this case, I comment as a result of: 1) is not quite exactly on the straights, which is unacceptable, 2) mesh density is not uniform, which is not desirable; and the process of creation: 3) Big Train with extra vertices and segments. It is necessary to leave only 3 + 2 rows of ribs to form fillets bowl, like this:

Hey, Max On your advice used 3 + 2 rows Rib: Here is the result after Turbosmooth: tools: chamfer, extrude, insert must admit that: Chamfer, Extrude, Insert Scale and spent 2 minutes, to create the shell. But accuracy is lame. Osovenno outer corners of the shell or compress can also Scalom?

Norm happened. Scale can be, of course. Then just make a reset Xform. As for the ribs, it is not necessary to do 3 + 2, 3 are in fact the edges - shaping, 2 - support. Depending on the situation, may be a different number of both. To determine the amount of the formative need to watch how many fins should be at chamfer, to obtain the necessary rounding without dithering, and support are added, depending on the need to make the corners or radii form so that it is not lost in the smoothing.

Aleh rightly pointed out, 3 + 2 is not a prerequisite, in different cases in different ways. Alternatively keeping accuracy, use not modfikator turbosmut and the mode "SW nurms sabdivizhen", available at the click of a checkbox in the book "sabdivizhen sёrfeys" (make sure that "Show Cage" is also enabled): this will simultaneously see and the basic grid and the final result . For example, you can adjust the model just below the reference.
