Modeling a Desk Lamp


Moving up.

From top viewport create a circle 8cm in diameter. Make an arc over that circle (and offset it inwards with 0.2cm) and create using sweep1 a surface using an arc as cross section curve, and circle as rail (for both arcs):


Make a rectangle 1.6cm x 0.2cm and position its center on the center of this semi-sphere (smart track will do the trick here):


that rectangle twice and move one copy up by 0.4cm and other down by 0.4cm. Then extrude those 3 rectangles, and trim:

From top viewport make a line:


that line on both sides by 2cm. Each offset line offset by 0.8cm on both sides and delete the middle one:


the selected two lines down a bit and position them on z axis so the fit semi-sphere:


Where the far left line of 3 right lines intersect the semi-sphere start an arc radius of 2cm:


Using polyline make a polyline like on the image below. Then join with an arc:


When you joined those, extrude by 1.6cm with cap set to yes, but you won’t even need to input that because you have far right line of those 3 right lines as a boundary for extrusion:


Now, select the closed curve we used for extrusion, and move it (from top viewport) by 0.2cm left, and 0.2cm down:


that curve over middle line, just so we don’t need the exact extrusion distance, we will simply use that one for boundary:


Now, lets fillet the edges of the outer shell. We will use 0.7cm as radius:


Now, lets fillet the edges of the inner shell. For that we will use 0.5cm as radius:


Now, using command, explode the surfaces of both shell sides and delete the bottom surfaces:


Create a line connecting the inner sides of inned shell, and then offset it by 0.2cm:


Extrude them:


the inner side of shell:


Create a rectangle:


its edges with 0.3cm:


Now, mirror the “handle”:


Trim those two handles with semi-sphere part:


Using , duplicate border.


Using create a surface:


those surfaces:


Now, using that rectangle that we filleted corners, extrude and trim with our object:

Now, finally, lets position our object so it looks connected to the “legs”:


Create two more circles, and make them the same radius/diameter as that one on the leg (check the image):


Using polyline or just line, connect those two circles Quad points:


Trim off the left half of circle, and close with line or simply with CloseCrv command:


Extrude using BothSides option so it fits the gap:


Now, extrude the circle with Cap option set to yes:


Mirror that part:



In this step we will make the interior for the lamp and the glass that covers it.

Select the circle we used earlier for creating the semi-sphere part:


Offset it by 0.2cm towards inside and make a planarSrf out of it:


Now, offset the circle again, but this time by 0.7cm:


Make an arc in that circle:


And you know the drill, make a surface (semi-sphere) with sweep1 command:


Now, create a line, and position its mid point to the quad of our semi-sphere. And then move it down (from top viewport) for 1.6cm:


Extrude, and trim with semi-sphere:


Now, trim the line with circle:


You can delete that circle surface, we will make another one πŸ˜€

Select outer circle and inner 2/3 circle:

Now, using that 2/3 circle, extrude it down by -0.3cm (minus is because we want to extrude down) and have the Cap options set to yes:


And that is it!!!!

    I like your side, news, video tutorials…etc. But in tutorials I would include also .pdf tutorial on the end (it is much easier to read and to see the pictures).

    Keep with good work!

    Best regards,

  2. Ivan Vuzem says:

    well thanks. I’ll think about pdf, if theres a good and fast solution to creating pdfs then fine πŸ˜‰
    thanks, I just hope few more ppl would find my efforts worth and help me out with writing tutorials, so I can learn something too πŸ˜‰

  3. leyla says:

    hey thanks alot for ur tutorials i reallyyy learned alot. but i just want to ask u a tinny favor …iz it possible to put the photos little bit big size. i know if i ckick i can see big size but when iam printing they became small:((( sorrri to asked alot

  4. GHaup says:

    Thanks a Lot Dude! It was very joyful
    Its impressive the way you make your tutorials… so detailed

  5. hokr says:

    thanks for your tuts!!!!

    great rhino tutorial, especially the shelling. i have a question: in a few places (e.g. third step on page 4) you do a trim that also seem to create fill surfaces. e.g. when you trim the three extruded rectangles through the shelled lamp head, you appear to be getting a solid result. When I do it, I have to creat the vertical fill surfaces by hand. Is this something you’re leaving out, or am I misunderstanding?

    thanks again, these are the best notes i’ve ever seen. i’d love to see pics & text of how you set them up, & how you measure the object for the modeling.

  7. Ivan Vuzem says:

    well, since we are extruding those three rectangles, and trimming the extruded surfaces with the shell, I suppose either you are doing something wrong, or you did something wrong πŸ˜‰ but keep trying

  8. michael says:

    Whenever I *trim* a solid with another entity (curve, surface, or solid) the result never seems to be closed; only if I do a *boolean subtract* is the result closed. E.g. make a cube and trim out a hole with an extruded circle: there will be two circular holes in the cube’s faces, but no interior cylindrical wall. If you send me an email address I’ll send you pictures of what I mean. But I really *want* it to work like you say! Thanks for any explanation…

    Bad Ass! Learned a lot during this tutorial!

  10. michael says:

    Oh, wait, I see what you’re saying: trim A to B then trim B to A and join…right?

  11. Ivan Vuzem says:

    well, boolean operations work actually the same as trim and join, but you do it in one step and one command and sometimes avoid unnecessary problems. I am just too much used to trim so I often forget to use boolean πŸ˜€

    teach me to know more about rhino.

  13. Flash Gordon says:

    It would be nice if the blueprints weren’t in pdf… ya know so you could actually use it maybe.. just a thought. It would be much easier to make the body shapes using profile curves from a bitmap but you can’t get a bitmap.

  14. Flash Gordon says:

    your tuts suck. I could getter better tuts from a retarded aspergers baby

  15. Ivan Vuzem says:

    You can look up on vector graphics on wikipedia if you can’t grasp how vector is more powerful than raster.

    And in case you didn’t know, you can export pdf-s into jpeg images which then you can insert into Rhino.
    With a little more “advanced” rocket science, you can actually import vector graphics as curves into Rhino, which is another reason why I provide vectors.

  16. A Rhino User says:

    Good tutorials – thanks! I agree with the presentation though – itΒ΄s difficult to keep flipping betweeen instructions and the images for clarification. Maybe you could use a plugin like Simpleviewer so that when you click on the image, it is overlaid over the current page at a large size.

  17. g.sahin says:

    another good tutorial!! thanks a lot again. but this time I had so much trouble with triming two surfaces in the 4th step. I can not trim just with one click, I mean after first trim there is still surfaces that I have to click on to continue triming. is it the only way or am I making a mistake? please give us some tips about triming…

  18. Luis says:

    Great tutorial.
    You can view my render in the forum πŸ™‚

  19. Alica says:

    Nice tutorial…:) Is there something like video of this?:)

  20. Michael says:

    Do you know if Rhino for OSX has the PlanarSrf command at this point. I am a newbie and cannot connect the surfaces making up the small circle to the big in part ten of step 1

  21. Paul says:

    Great tutotial.
    I can really use some steps for my next project, on which I now was stuck.
    Do you have also vids on YouTube?
    Best regards Paul

    what is Rhino OS X
    Is this a 3d software
