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.

Ok, first things first. We need reference image which will help us model this little bugger. So, please use this one, and position it on the background of Top viewport. Make it 40 units (make sure you’ve got your Snap turned on) in width.  Like so:

STEP 1

Then using Rectangle command create one rectangle like on the image (please note, if you followed the above intructions then you will have absolutely no problem aligning with using snap rectangle corners according to the image)

You can explode that rectangle into 4 lines with explode command, and then offset upper and lower ones by 2 units towards inside:

Now, create an Arc using Mid Osnap option  and position it like on the image. (you will have to turn off the snap option, and turn on the Ortho for moving the arc straight). After that trim off the lines you don’t need with Trim command.

Ok, lets get to the third dimension now Join all curves and lines, and extrude them with ExtrudeCrv command (make sure you have Cap set to yes). Extrusion distance is 5units:

Now, offset joint curve by 0.5 units, and move that offset curve upwards (from Front or Right viewport) by 0.5 units, and extrude it by 4 units.

Using FilletEdge command, set the fillet radius to 0.6 units, and fillet all edges (of both outer and inner objects).

Now, using Rectangle command (make sure you click on Rounded in Rectangle options before setting first corner) create rounded rectangle in Top viewport and position it like on the image below:

Copy it 5 times, and mirror those 5 so you get something like on the next image:

Using Project command, project those curves on both objects:

Trim the upper surface with upper curves like on the image, and inner curves with inner surface:

You’ll have to end up with something like this:

Now, isolate two curves like on the image. We will create surface between those two.

As you can see, there are actually couple of lines and couple of arcs combining these two curves. So, at each intersection of lines and curves, there is an end. So, using End Osnap option, and Perp we will create cross section lines.

Now, using Sweep2 create a surface using two curves as rails, and other cross lines as cross sections:

Copy and mirror to fill the rest of the gaps:

Join all surfaces, and using FilletEdge command fillet new edges (do not worry, you can select everything with your bounding box, as there is no other edge that can be filleted except the ones we need ) . Use 0.1 units as filet radius.

STEP 1

We will start from the bottom up. So, first we will model the bottom plate. Create two circles from the top viewport, one 11.9cm in diameter (if you see a diameter option in Circle command, click it so it turns into Radius – that means the diameter is on) and other 11.5cm.

Then we will need three more circles (you can make them anywhere, just make them concentric). Make them 0.3cm, 0.6cm and 0.8cm in diameter.

Now, using Mid, Quad and Cen options in Osnap, position these three little circles on the End (or Quad) point on the outer bigger circle. And move those three from right to left by 0.85cm.

Now we need three more groups of those 3 circles. So, we will use Arraypolar, and array them 4 times around the center of bigger circles (in my case that is 0,0 as I usually have my models in the origin).

Now, select the inner circle of two big, and outer circles of each three-group circles and move those circles up by 0.25cm (from front viewport):

Now, select and copy the inner circle of two bigger, and move it up by 0.55cm

Now, copy the outer circle, and move it up by 0.8cm:

Now, back to those 3-group smaller circles. Select the inner one (4 of them) and move up by 0.75cm. Then, copy those moved circles, and move the copied ones up by 0.2cm.

Now, pick one group of circles, and we’ll start making the boss. Create a surface between two smallest circles. I used extrude, but you can use Loft as well.

Now, the bottom one, I’ve extruded it to the bottom small circle (here, if you want to use loft, you need one more circle that is in the same construction plane as the bottom smaller circle).

And then, extrude the biggest circle to the upper small circle:

Now, we need to create the surfaces between inner and outer circles. We’ll do that with PlanarSrf.

Join those surfaces, and ArrayPolar like we did for the circles.

Now, we’ll make the bottom surface, so select outer circle, and 4 little ones and using PlanarSrf make a surface with 4 holes (just run PlanarSrf command and hit enter):

Repeat the same step for upper 5 circles:

Now, using the Loft command, make a surface out of outer circles (Use the straight sections in style option) :

Join those surfaces, and we’re done with the plate.Theres just one thing to do, that is fillet the edge. So, using FilletEdge and 0.1cm as radius, fillet the shown edge:

In this tutorial I will show you how to model a plastic bottle. To be more precise, this is a Domestos bottle. But the same method can be used to model any kind of bottle like shampoo bottle.

STEP 1

Ok, before I forget, the background image in top viewport is 208 units wide, and the one in Front viewport is 191 units wide. Ok, so after you set up your image references, we can start with the base of our bottle.

We will first make two lines with Polyline (or Line) command and make the second one go through the middle of the first one. You can either make the lines first, and then using Mid osnap option position the two lines in their middle, or you can make a longer line with Polyline and then using Line: From Midpoint (From lines menu) and start that line from the middle of the longer one…

The longer line is 92mm, and the shorter one is 60mm. If you use Midpoint line then input half, 30mm.

Next, create a circle of Radius 85mm anywhere in the top viewport. And then, using Quad option in Osnap move the circle to fit the end of the shorter line.

After you’ve done that, we need to mirror that circle over our longer line and then make two lines at each end and perpendicular to the longer line.

Trim the parts we don’t need, and fillet the corners with radius of 25mm.

Now make an ellipse 84mm wide and 54mm high.

STEP 2

Join all curves into one closed and extrude by 170mm upwards.

Next, make a line at the mid of our extruded ellipsoid.

With InterpCrv command make a curve and then using match command match that curve to be tangent to the line we just made:

In the Front viewport, from the start of curve make a line like on the image below and make it 50mm long, then from that line’s middle point, make another line 40mm long (it would be very helpful if you use Line: from Midpoint). Next, make another line perpendicular (use Perp option in Osnap) to those two lines, and make it long enough as the cap of this bottle is. Now move the 40mm long line along that perpendicular line so it fits the image.

Create two circles with center on the perpendicular line, and end point on the end of each line (the ones 50mm and 40mm). The easiest way to do this is from Perspective view. Mid and End options in Osnap are very helpful here.

Now on the other end make a small line as on the background image:

Now, make an interpolated curve between the upper end of this small line and bigger circle:

Using PointsOn command show the control points of that curve (that is still showing as a straight line – but not for long). Now move one of the control points to the left a little :

Fillet the curve and little line with 10mm radius.

Now, you can turn off the control points with PointsOff command.

With Sweep 2 rails (sweep2) command select two opposite curves as rails and the bigger circle and the surface edge as two cross sections:

Ok, first, sorry for delay, I’ve been meaning to write this one down for 4 days now.

I must say that I’m pretty happy with this one, it turned out very accurate and great. I really like it! And it is pretty easy to model it. So check it out:

STEP 1

Ok, first things first, so lets start with tubular part. The part where the motor and heater is. I’ve measured 120mm the length and make a line with Polyline or Line command (the length of our reference image is 190mm). We will make three circles two on the start and end of line, and one 30 or 40mm from the left circle. You need to offset them by 2mm, or simply make another circle. I made another circle, so in the end I ended up with 6 circles. Far two right circles are in radius 26 and 28mm. The far left two are 34 and 36mm, and the inner two are 35 and 37mm.

Using InterpCrv command make a line connecting three outer circles. (use Quad option in Osnap for easier snapping). Next, do the same step for 3 inner circles.

Using Sweep2 for first and second rail select outer two circles, and for cross section curve select Curve we made earlier.

Make an ellipse and position it like on the image below:

Next, from Front viewport use Project command to project that ellipse onto our tubular surface. You will get two curves on the surface, and we need only the front one. Using it, we will trim the surface and make a hole:

Now, we’ll move onto handle. I like jumping from one part to another, I guess you already found that out

From top viewport using reference image, outline outer edges with InterpCrv. Just to make sure, I made a straight horizontal line in Top viewport (using Ortho) and trimmed off the two curves. Now, we are sure those two curves has endings in the same cplane.

Create another ellipse, this time one radius 15mm and other 13mm. Using End and Quad options in Osnap, position the ellipse between two curves, first move it to the end of one curve, and using PointsOn command, stretch the ellipse to fit the other curve’s end.

Copy that ellipse, and position it like on the image below. You also need to stretch it with moving control points so it touches both curves. I have also made this ellipse 4 points higher. So, select upper three control points and move them 4 units up, and then move lower three control points and move them by 4 units (mm) down.

Next, using that second bigger ellipsoid and two handle curves, we will make a sweep2.

Using DupBorder we will duplicate border of newly created surface. We will get two closed curves, and we need the little one only, as we already have the bigger one. So, now, delete the surface, and again create sweep2 rail between two rail curves, and using now three closed curves:

And now, we have a handle! Next, we will blend the two surfaces, so use BlendSrf command. Note that we need to check the Same height shapes option:

Hopefully you got something like on the image below:

Blueprints (required registration, but I think it is worth!)

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:

As you might notice, all these tutorials are pretty much the same. This is the method I use, and find very good. First, make the shape of the model, and then cut the details.

Well, this time we I won’t be showing you how to set the reference images in the background, as I think you have learned that from previous tutorials (I’ll add in tips & tricks section how to insert these, for future reference).

RESOURCES

STEP 1

We’ll make a rough outline trace for the speaker from Front viewport. Using polyline create 4 lines and position them using rotate like on the image below:

Then, using Trim command, trim off the parts we don’t need, so we have a closed curve. Fillet the left upper and lower edges with 12 units (I have set the resource image width to 83 units, just for the aspect ratio reference).

From top viewport, adjust the closed curve so it matches the angle as on the reference background.

Next, from the upper left corner (in top viewport) make a straight line 80 units in length. Using PointsOn turn on the control points for the closed curve, and using RemoveKnot command, remove two outer fillet knots on each round part.

And mirror that closed curve using this straight line’s mid point and Ortho option.

Using these two closed curves, create a surface with Loft command.

Close the objects both left and right sides with planar surface command (PlanarSrf) and join those three surfaces in one object.

Next, we need to make the back side curvy, so lets create a curve with Interpolated points (InterpCrv) like on the image:

Extrude the line (you can use Bothsides option to make sure it goes outside your object). Also, you will probably have to adjust the direction of extrusion, and you can do that by clicking on Direction option of Extrude command.

Trim off the parts of both extruded surface, and that object. After that, join the object.

Now, we will create a curve for splitting the base model. We are using the same method as for creating the rough outline trace as on the beginning of this tutorial…

We do this step again for top curve:

Using filletedge command fillet the two edges where our new curvy surface touches the flat surfaces.

From frot viewport, project the curve on the base model. You should get this:

Do the same for the top curve, but Project the curve on the object from Top viewport.

Copy the main object with Copy command, and paste it with Paste command (CTRL+C and CTRL+V works here). It is better to first copy, then trim the base object with one (either top or front curve) then paste that copied object and do the trimming with other (if you first trimmed with front curve, then now trim with top curve) curve.

Using earlier projected curves we will create cross sections between them with polyline command.

Mid and Perp options in Osnap toolbar are very helpful here. Near option is also needed here. Proceed with creating cross section lines until you get something like this (please not those lines need to be perpendicular to the curves).

Using sweep 2 rails (sweep2) command and set the yellow two curves from upper image as two rails, and other lines as cross sections. And tick the Closed Sweep option.

Unhide all the other parts, and join this surface with other two.

Now, you can explode that as we will be offsetting (offsetsrf – I have offset by 0.5 units) the main two surfaces and we’ll again create the cross section…

Using Duplicate border on the offset surfaces create the rail curves.

This is the same way of creating the object as few steps before, but this one is by 0.5 units smaller. I believe we could simply scale down the bigger part, but hey, this is me, and I’m making this…

Ok, so we made an alternative to non-existing shell command in Rhino3D v4 (rumor is that in v5 there will be shell command-yey!).
