Final model

# Modeling a Garden Shovel

## STEP 2

In this step we will model a handle. With command create a point on the back of the handle part we have. Position it in the center by using Cen OSnap option:

Now, lets go to Right viewport and create two circles using that point we just created as center. If you haven’t already turn on the Point OSnap option. Make one’s radius 2.2 units, and the others’ 2.7 units:

Using command, we will create a line anywhere in the Right viewport

it with command, starting from the Line Mid point and move it to Quad point on the smaller circle.

Now, use Move command again on that line, and move it down by 0.35 units. Start Move command, select the line, input 0.35 in line command, press enter and move down. To move it perfectly straight down, use Ortho option in status bar:

that line with command. Use two opposite Quad points on either circle to form mirror line:

First, select all circles and lines, and start command. Start clicking on the parts we don’t need. The ones you don’t see in the picture below:

Don’t forget to all lines together. Move the polyline on the start of the handle like on the image below: Using command, fillet the corners with 0.2 units.

Extrude that closed curve by 0.75 units:

Using command, offset the edge by 0.2 units:

Move that circle by 13 units left like the curve before:

Move that circle right by 0.1 units. Why? Because right now it is right on the same position like the ring surface, and when we extrude this circle, we will have two surfaces on the same place, and that will lead to some problems in the future when using booleans.

So, extrude that circle with command by 18 units and using connect with the ring.

Offset the far left edge by 0.2 units towards inside:

With command, create a hole using this circle through the handle:

Now, using command select the edges on the ring part, and fillet with 0.05 units as radius;

Using command extract this surface:

the surface, and using move the inner edge by 0.2 units towards inside:

Now, using Cen OSnap option, place two points with Point command in the center of both circle edges:

With command, create a sphere with its center in the Point, and for the second point click on the end/quad of tube circle edge:

Using   we will split this sphere into half, and delete the inner half:

Do the same for the bigger edge.

Using Line command, create three lines like this:

Using Explode command explode the handle surfaces, and with the vertical line split outer tube surface:

Offset line to the left by 0.2 units, and using that offset line split the inner tube:

Now Offset the two horizontal lines towards the center of the handle by 0.2 units:

Again, with Split and/or Trim trim the parts for the holes:

Using PlanarSrf command “cap” the tubes:

Using FilletEdge with 0.25 units as radii, fillet the edges where you previously created two planar surfaces:

Using command, blend the two surfaces and fill the gap. Then with Join connect the surfaces:

With Move command, move the part from its Quad point, to the tube Quad point.

With command, create a rectangle 0.5 units wide, and position it like on the image below. For the height, use what ever as long as its upper part goes over the handle tube:

Now, with copy that rectangle along x axis by 1 unit:

Next thing would be the grips. So, use one of the existing circles, and offset it by 0.1 units outwards:

Isolate the outer shell of the handle, extrude with ExtrudeCrv command the offset circle:

Select everything, and using command, from Front viewport project the rectangles on two tubes:

Ok, now, where the projected rectangle is, the inner cylinder should be visible, and the outer cylinder should be trimmed:

And for the end, we need to create a surface to fill the gaps. We’ll do that with Loft command, and two curves that are on the edges of those holes:

Now, either or Array that surface to fill the rest of the gaps.

And for the better effect, we need to fillet the edges

And this is what you get in the end:

This is one of the worst tutorials I’ve ever worked through. Why would you put half of the model off the grid and then say “the proportions are crucial here.”? Pain in the ass to get through this thing.

2. Ivan says:

well, first of all, the grid is a representation of a plane on which you create your models, often called construction plane. Of course you can expand it to show more grid, but isn’t really necessary if you have and follow grid snaps. Because the grid is just showing you where will your cursor snap to, visually, while you can obviously see for yourself where your cursor is snapping when using Snap to Grid option.
Grid is just ONE modeling aid you can follow to model your way through, and most certainly is NOT the number one thing for modeling accurately and fast.

Thanks,but there‘re errors in this tutorial，some pictures don’t match the instruction.

4. Ivan says:

5. I got a problem with FilletEdge command. Can you help me? See the pic.
I remake it many times and nothing useful…

6. JTex says:

I found this tutorial frustrating as well. It was slow going up to the boolean join of the handle and spade at which point I have lost interest and will find a more detailed tutorial elsewhere. The extrude isocurve took a while to perform as I had difficulty selecting the center of the ellipsoid. Simply suggesting “use the quadrants” or whatever was not helpful. But, I finally got this done. Not a big deal, just where things started to get frustrating. Most frustrating was the boolean join. I could not get this to work. Even after reading in the FAQs about why booleans fail and attempting a step by step – Intersect, Split, Join, Delete – which did not work. I couldnt get the ellipsoid to split. Anyway, I find the video tutorials helpful as you can watch the actions being performed. I might try these again at a later time, but now I need a beer.

7. blip says:

What’s the environment map on that geometry?

8. Chris says:

Hi, thank you for sharing all your tutorials, they are very helpful when learning rhino!

I do agree that sometimes things aren’t explained clear enough for beginners, but I understand that it’s not that easy to write a tutorial as when you are an expert at something it’s hard to remember what is and isn’t simple.

One thing that i’m curious about and REALLY hope you can answer is that in your models, your same surfaces have the minimum amount of isocurves needed, but mine (following your instructions) have loads more isocurves. Is there a “regen surface isocurves” tool or something that gets rid of all the extra/unneeded isocurves?

Thanks a lot again.

9. kyla says:

i got lost at the trim part. it doesnt explain how to use it. the whole rectangle just lights up. if this tutorial was for beginners it would explain how to use the commands. it seems there ar very few good tutorials for this frustrating program T_T

10. Mark says:

Good tutorial. One has to know the basics to follow it (for those who criticized it). I learned a couple of good techniques from it. Thanks.

11. Ali says:

Great tutorial! I’ve learnt some good techniques from it as well

12. Ali says:

Just a question…why don’t we use offsetsrf and use the solid option to turn a surface into a solid right away? just seems more direct to me than blendsrf

13. Ivan says:

well, with blendsrf we blend and make a round section edge, if you know what I mean. With solid offsetsrf you get flat side surface which then you would need to fillet, and then you could get into more trouble than with this method

14. Nate says:

As someone who has never used Rhino before, I would have appreciated not having to scout through millions of commands to find the ones that you have mentioned. You ought to let the reader know where the to find the commands you mention. Also, when I made the ellipsoid, it did not appear as a solid shape only as 3 ellipses. Was there something that needed to be turned off or on to get a proper solid?

15. Ivan says:

the reason why I am not explaining where each command sits in which toolbar is simply because it is not needed. The commands are easily started from inputing the command names into command line.

And if you search for yourself all the buttons you need, then you can decide for yourself whether it is more handy to use buttons or just to type in the command name, not to mention that that way you will learn much better (but not quicker). In the end you will find yourself using all methods of starting commands, using toolbar buttons, command prompt, keyboard shortcuts, or drop down file menu. It is just up to you.

One more thing, under Help menu, you have command help, which updates automatically as you start commands, so I give you the command name, you type it in command line, the command help updates and gives you all info on the command, and you get “where to find” info on the command as well. So, really, I don’t think explaining where each button sits while you can edit your toolbars completely, is needed.

16. Ivan says:

and about the ellipsoid. Not sure what you’re saying, but it seems to me that you somehow missed the perspective view. When you start Rhino you should be presented with 4 views, three orthogonal and one perspective. The three orthogonal are actually views from top, right and front, while perspective represents your model in space in 3 dimensions. Normally if you look at the ellipsoid which is an object from either orthogonal view, then it would be presented to you as 2D shape, which in this case is ellipse or circle.

or, you just need to right click on the perspective label and click on shaded to get full 3D representation of your model. The default is set to wireframe, which is one of the standard 3D viewport representations.

17. FenderTalker says:

I like this tutorial, enough good described. Please, post more like this one. Thanks.

18. s2kslav says:

this has been a frustrating tutorial, Ive gotten to the part right before Offsetting the surface, but do not know how to make the “shovel” curve into a surface. It seems that step has been skipped. can you elaborate?

19. Ivan says:

If I’m not mistaken about the place you got stuck on, then everything is explained. There is one little lapsus in the text but that shouldn’t stop you from getting the right shape. So, you got your closed curve you made in your top viewport, and you got your ellipsoid solid object, you just need to project that closed curve onto the ellipsoid and cut the ellipsoid with the curves so you get your nice surface which then you can offset.

20. Ivan says:

p.s.
when projecting, you should project from TOP viewport like it was indicated, not from FRONT viewport, like it was suggested later. That was a lapsus.

21. Fuyi says:

Still working on this tut but it is quite a challenge. I don’t think total beginners can really follow this but to those people I would recommend reading through the tutorial pages in Rhino help and downloading the Level 1 Training manual from the Rhino site. Those should help you get more familiar with the basic commands of Rhino.

22. Dani says:

Hi.Thank for your helpful tutorial. I’ve problem in last section (image 56). When in filletedge command want to select edge, any edge couldn’t be selected

23. Ivan says:

you need to join the surfaces first. I might missed to mention that.

24. kevinxu says:

Done! I just finished my shovel. I followed your steps with no problems. Thank you so much.

25. Jason B says:

Great tutorial. For those having a lot of problems I suggest playing around with Rhino more. I have learned mostly by playing around and trying commands to see what they do. I actually trimmed the handle in half lengthwise and mirrored the grip and joined it back together for grip on the underside to improve grip look.
Remember, unless you are making a model for work or school, don’t stress and have fun!!!!

26. CDM says:

While this is a good model for a beginner, your steps can be a bit convoluted at times. For example images 25 through 30 don’t clearly reflect their associated steps.

“Using Offset command, offset the edge by 0.2 unit” – Which edge? One of the circles at the base of the handle or the 0.75 extrude.

You tend to jump in and out of saying ‘like the image below’ and giving concise measurements and actions. Stick to one or use both consistently.

Again, I’m not saying this is a bad tutorial. It’s free. I can’t complain about that! Only perhaps you should improve the steps a little as this is the first tutorial people come to and could deter people from some of your other (better written and more complex) tutorials.
