INTRODUCTION

I really liked modeling this model, it turned out really good, and I must say that it was pretty easy to model it too. However, there is fairly enough playing with Osnap, but then again, when do we not use Osnap frequently? Anyway, to get you started, you first need to download some kind of blueprints I made for you out of this model. You just gotta love that Make2D command!!!

Blueprints reference

STEP 1

First things first, we need to setup our blueprints. Not only import them into Rhino, but also position and scale to fit the dimensions marked on them. First, go to Front viewport. You can expand it by double clicking it. Next, using PictureFrame command browse for blueprints you previously saved to your computer. Now, you don’t need to worry about how to position or how big you should make it. We will fix that in a bit, but just make sure your blueprints are not tilted. For that you can use Snap, or even better Ortho.

INTRODUCTION

Ok, this is another tutorial on modeling some ID product. I’ve tried to simplify this to the bare bone, and I hope I managed to do it. Actually, this is a method you could use on various other projects too. This is what it all comes down to, all you need is create a set of base curves right, after that it is all just music to the ears.

STEP 1 – creating the curves

In the images in this tutorial, you will notice I have 20×20 grid system. You can take a look at my previous tutorial on setting up and prettifying user experience by changing grid and other settings. That will give you an idea how to change your grid system. Basically it is just grid option Extents that is set to 10.

To start off, we will need 4 points. We will use those 4 points for creating a curve. So, go ahead and maximize your Front viewport and create 4 points with x and y coordinates as set: x=-17, y=1 / x=-5, y=-1 / x=9, y=-2 / x=22, y=-1.

create 4 points

Using Curve command, create a curve between those 4 points. To make it easier to snap to the points, just use Osnap option Point. Next, create a line horizontal with start at -17,2 and end at 22,2. We’ll need one more line with start at 7,3 and ending at 8,4. You can create them with Line command or just PolyLine.

two more lines

Next we will create one polyline and one line from Right viewport. Use PolyLine command and for 4 points of polyline use: -4,-5 / -2,-10 / 2,-10 / 4,-5. For the line use PolyLine or Line command and for the start and end use: -5,-8 / 5,-8.

creating some more lines

Using Trim command, just trim off polyline and line, leaving everything above the line. Once you do that, using PointsOn command, you simply show control points of two tilted lines and move the upper control points up by 1 unit.

trim and move control points

In perspective viewport Move (or Copy) that polyline from Mid of the middle (straight) line, and move it to the end point of the first curve we created (22,-1).

moving polyline

Go to Top viewport, and from there create a curve with Curve command (-4,10 / -10,0 / -4,-10).Note, it would be smart to disable Osnap for a second when you are creating this curve. You might get in trouble at middle point if you have some Osnap options on, so to avoid any possible problem, just disable osnap for this step.

just another curve

Move that curve 6 units left. So it just touches the grid. From front viewport move it up by couple of units i.e. 5. Using Rotate command and clicking on the Copy option in command line we will create one more instance of the curve but rotated by 90 degrees. Then, if you haven’t already, enable Osnap, and using Mid option move that curve to the first point of our first curve (-17,1). Use Osnap option Point to snap to that point. Otherwise if you want to input the coordinates, you would have to do it from the same viewport where you created that point, so from Front viewport.

Rotate & copy, move

Ok, this step might get a little confusing, so pay attention. We need to set that curve to face the curve perpendicular. Check the image to see what curves I’m talking about:

what to do

Now, we need to rotate vertical curve so it is perpendicular to the bottom curve. We’ll do that by first creating a line that is perpendicular to the curve below. So, start your beloved PolyLine command, and hover your mouse over the Osnap options, and while holding down CTRL key, you will reveal some more Osnap options. Click on the second one, PerpFrom. Now, you are asked to select the curve on which you would like to show the tracking, so select the lower curve. Now, you can move the tracker where you want to start your line from, and move it all the way to the left (Point Osnap option might help, or end).

PerpFrom osnap option

Now, we created a line that we will use for a rotation angle.

Now, just rotate from Front viewport the curve to fit the line angle.

Now, repeat this step for the other end of the curve and other section polyline:

repeat for this side as well

Introduction

Right, in this tutorial I will not go into depth of either VRay render options or materials. But I will go through creating your own materials rather than downloading them from internet. So, lets say this one is for real ultimate beginners.:P

Final Render

So for this tutorial, naturally, you will need a model of a bulb. So, you should first read and complete Modeling light bulb tutorial and create yourself a model. Oh, you’ve done it already? No you actually just took the finished model from the tutorial? Ah well, it is up to you actually.

If you haven’t already, download light bulb model here:

Final model

Ok, next step would be to set up your texture files. There is going to be some text written on the body of this bulb. So since I don’t have this kind of bulb at home, and I don’t know what is actually written on this one, I did some google searching and gathered some images. From Fresh2 website you can download some nice material like vector logo in .eps format and some images. And using some images from google I managed to recreate somewhat real looking textures. To save you some work, I will attach my finished textures here. You need one real texture that you will wrap around your model, and another called mask. It is basically black and white version of an original texture which tells our VRay where it will be transparent and where not. So, white color is marking the transparency, and black non transparency.

STEP 1

Ok, now that we have all our material, we can actually start. You can delete all layers except “default”. Now using SelCrv select all curves and delete them. We don’t need them anymore.

Rotate the bulb 90 degrees counter clock-wise in front viewport and using Line (or PolyLine) command make one line:

image 1

Again, using Rotate command rotate bulb from one line end to another as first reference point, and then using Ortho rotate so that line gets in a horizontal position. Then using Snap position it so the line is on the x axis like on the image 2:

Now, from the top viewport using SrfPt command create one surface. If you use Ortho and STrack it can help you create equal sizes surface.

image 3

Using Rotate (click on the Copy option in command line so it copies when rotating) create a copy of that new surface. Copy in right viewport:

image 4

Using FilletSrf fillet the two surfaces with around 100-200 units as radius. It depends how big surface you created. Ok, now we have created some simple scene for our model.

Next, we will start creating materials, but before that we need to set up couple of vray settings. Like output dimensions, you can set to 640×480 or 800×600 for testing purposes. In the Global Switches uncheck Batch render so you can work inside Rhino while rendering. Otherwise Rhino is “blocked”. You can hit the Render just to see the test. It is always a smart thing to do, to hit the render just to see the changes you’ve made to either materials or vray options.

Ok, now, instead of GI we will use HDRI for our scene illumination. To do so, go to Environment rollout and click on the small m next to GI (Skylight). A window will open, and there under Common, set the Type to Bitmap, and then on the right where it says Bitmap, File, browse for a HDRI map you have on your computer. If you don’t have one, use this one.

If the scene is too bright or too dark you can adjust it using multiplier just under the Bitmap drop down menu where you put the HDRI map.

STEP 1

Again, in this tutorial I have also skipped the blueprints setup.

First, create 3 outline curves in Front viewport with InterpCrv and bridge two upper with one line using polyline (good to have osnap Near option turned on)

Next, split those two bridged curves with that created line (bridge).

Create using InterpCrv outline for the handle section, and offset by 1 inside.

Trim the two curves and split outline curves.

Then, from right viewport, create three lines, and Fillet the corners with 1 unit. Offset that curve by 1 unit inside, and you will create another instance of this curve, but this one won’t have filleted corners.

Extrude those two curves and trim two newly created surfaces with the curves in Front viewport.

The two curves for handle section need to be positioned on the center of your base surfaces. I’ve done that by first creating the surface with Surface from 3 or 4 Corner Points command (SrfPt) and I positioned that surface on the middle of my model. I’ll use that surface for future centerings (I hide it when not needed).

When you moved those two curves to the center, extrude them according to image below:

Here, I’ve used BothSides option in Extrude command. Notice the Top viewport to see the extrusion distance.

Blend the edges of coresponding surfaces, check image below for reference…

Connect blend curves with lines on the mid

Using Network Surface command create surface out of two blend curves and one line.

Do this step for 3 other parts, and join the surfaces. Next, we need to blend the inner and outer surface… I used 0.5 for both sides blend bulge.

In the picture above you can see that I didn’t use blend for connecting the two network surfaces, instead I used Sweep2. Do that 3 more times for other surfaces.

And for the little 3 curved surface corners I used Sweep1:
