Modeling a Desk Lamp

STEP 3

In this step we are moving up. We will model that metal legs. I don’t know how to call them.

We need another circle. You can use one of the existing as a reference for center of our new circle. Make this new circle 0.62cm in diameter.

lamp_tut_73.jpg

You can move it down (from front viewport) just so it is under the opening of the tube hole. We don’t want to see the starting of our “leg” surface.

lamp_tut_741.jpg

Now, make a line (either polyline or line) starting from Quad point of our newly created circle. Make it 13cm long.

lamp_tut_75.jpg

Make two circles on that line, and make them 0.05cm in diameter. The distance is not that important, just position them like on the image below:

lamp_tut_76.jpg

Next, trim off the outer semi-circle, and fillet the corners with 0.05cm radius:

lamp_tut_77.jpg

Using sweep1 use the circle as rail, and this line as cross section curve.

lamp_tut_78.jpg

Now, you will probably run into some weird problems. Like, maybe if you try to Shade the viewport, you will notice that you can’t see the little holes you just made. Well, that isn’t your fault, it is just because the Meshing in Rhino is set to default, that is low quality, better performance. But if you go to Tools->Options and under Mesh select Custom, then you will get good Meshing, but somewhat slower performance.

Now, create another circle on top of our leg tube. Use Cen osnap option. Make this one 0.52cm in diameter.

Extrude that newly created circle by 11.5cm up and move that circle you used for extrusion up a little (from front viewport):

lamp_tut_80.jpg

Connect the circle and edge of extruded surface with . Turn on the control points, and edit the curve:

lamp_tut_81.jpg

Using sweep2 select edited curve as cross section, and circle and tube edge as rails.

lamp_tut_82.jpg

that lower leg, and move the original circle up:

lamp_tut_831.jpg lamp_tut_84.jpg

Now, copy and paste that circle, and move it down by 2.5cm from front viewport.

lamp_tut_85.jpg

Now, create another circle, this one needs to be 0.9cm in diameter.

lamp_tut_86.jpg

Position it like on the image below:

lamp_tut_87.jpg

it and move it up:

lamp_tut_88.jpg

Next, use loft on selected circles, and as a Style option choose Loose:

lamp_tut_89.jpg

On lower two circles use loft again:

lamp_tut_90.jpg

Make another loft between upper and lower circle:

lamp_tut_91.jpg

Now, make a rectangle 0.35cm in width, and make it long enough so you can trim the surface we just made (from top viewport):

lamp_tut_92.jpg

Extrude it just so it is bigger than the surface we are going to trim:

lamp_tut_93.jpg

Now, clearly, this extruded rectangle is still not positioned right, so we will move it towards inside so the trim goes well:

lamp_tut_94.jpg

Now, trim the hole in our surface πŸ˜€

lamp_tut_95.jpg

Now, join everything, and mirror:

lamp_tut_96.jpg

Now, create a line between those two parts. Quad osnap option would come in really handy here:

lamp_tut_97.jpg

Now we need to extend this line’s both ends:

lamp_tut_98.jpg

that line on both sides by 0.075cm. Then create two lines each connecting two ends of opposite offset lines:

lamp_tut_99.jpg

Extrude that closed curve (set cap to yes), and make it high as your two tubular surfaces.

lamp_tut_100.jpg

If you like, you can trim two tubular with this rectangle object.

Now, lets continue with the legs. We have one leg to mirror, so mirror it:

lamp_tut_101.jpg

On top of one leg create another circle, and make it 0.45cm in diameter and then you extrude it by 11.5cm.

lamp_tut_102.jpg

Now, we will create an between two legs (the upper one, and the one below it):

lamp_tut_103.jpg

Using sweep1 command, make a surface:

lamp_tut_104.jpg

Now, on top of the upper leg, create another circle 0.6cm in diameter. Extrude it upwards by 1.25cm:

lamp_tut_105.jpg

On top of that, create an arc for a semi-sphere cap (from front viewport):

lamp_tut_106.jpg

Using sweep1 select an arc as cross section curve, and circle edge as rail:

lamp_tut_107.jpg

Cap the two lower circular edges with :

lamp_tut_108.jpg

From right viewport create a circle 0.4cm in diameter. Extrude it so it goes out of your capped object:

lamp_tut_109.jpg

Now, trim off the inside of this tube, and the tube parts that go outside your leg :

lamp_tut_110.jpg

From top viewport create a rectangle, and make its width 0.2cm, and length just enough so it goes out of your leg:

lamp_tut_111.jpg

First, position it using Mid option in Osnap, then like on the image below:

lamp_tut_112.jpg

Extrude this rectangle (you should have cap set to yes, but if you don’t, set it to yes):

lamp_tut_113.jpg

, so you get the hole in your “leg” :

lamp_tut_114.jpg

Mirror the parts we didn’t mirror and you should have something like in the image below, meaning this step has come to an end:

    Congratulations!
    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,
    uros

  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!!!!

  6. michael says:

    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…

  9. Noah Phense says:

    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. http://en.wikipedia.org/wiki/Vector_graphics

    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
