Creating a 3D model

In this tutorial, we will 3D model a mug. We will cover the most important and useful options, but we also encourage you to explore all the options of Modo, there are numerous tools that make 3D modeling very easy.


  • 2.1. Create the basic shape
  • 2.2. Smooth out the shape
  • 2.3. Designing the handle
  • 2.4. Results

Let’s start with a cylinder. You can either click on Basic and the cylinder icon in the top bar Geometry > Primitive tools > Cylinder. You can edit the measurements to get the perfect size on the left toolbar.  


Next, we want to delete the horizontal lines of the cylinder. To do that click on the Edges selection (marked in orange on top of the image). Or go in the top bar Select> Edges.  


With Shift add the rest of the edges perpendicularly.

At this stage, we will use a very useful option. Press L. Voila! Modo selected for you all the rings over your Cylinder.

Press Delete.


Now use the Polygons Selection tool and select the top of your cylinder.


To create a mug we need an extra surface which we can move inwards in the cylinder. To add that we used two options in the left sidebar. In Basic, click on the Scale (marked in orange on the picture), adjust it to be symmetrical and bring down with the move tool to have a flat top of the cylinder.


Tip: If you wish to see through the object, which is crucial for the next step, change to Topology view.


To create the bottom of our mug, we used the Bevel tool. You find it in many places, we used the one in the Basic section. Drag the selection down with the blue arrow. Make sure you leave space in between the bottom of the outside and inside of your mug (shown on the picture above).  

Now we will move on to creating soft edges on the bottom of the inside of the mug.

To do that we will also use Bavel. But instead of pulling on the blue arrow, we will adjust the red cube. If it’s not symmetrical, which has happened to us, go to Item> Transform> Freeze Scale.


Repeat this action by clicking in the middle button of your mouse. We create those extra edges to get a smoother angle.

To check how sleek are the angles press Tab. Modo will then automatically smooth out your model.

You need to scale down the last edge you create as much as possible.

Now, select all the vertices of the last circle created. Go to Vertex on the sidebar and click on the Join option. Modo will show a dialog window asking to join X number of vertices. Click Ok. We do that to make sure our 3D model is printable and smooth. 



Next, we will work on the bottom selection and we will use the same method. Select the bottom face of the 3D model. Use Bevel to create new edges, move and scale some to create the shape of the bottom of a mug.

Join the vertices of the last circle as we did on the inner side of the mug.

Now that we move on to finishing off the top of the mug. To do that Select all the edges by Selecting on pressing L.


To achieve a nice angle we will use the Loop Slice option in the Mesh Edit on the left bar. Set the Count to 2 (left bar) and set the percentage accordingly, we set it to 10% and 90% (top left violet line).


In the next step, we will create the handle of the mug. To prepare the object for that, we will again use the Loop slice. Select all the edges around the mug, click on the Loop Slice and change count to 4. Set the percentage as you wish, we had it set at 10%, 20%, 80%, 90%.


In this chapter, we will create the handle for the mug project using the Bridge tool.

Select two faces to work on.


Again, using Bevel extrude the polygons.




Create third extensions and adjust the angles accordingly with the rotate tool.


Once we’re satisfied with the shape, go to Basic > Bridge on the left sidebar. Set the Segments number to achieve the right angle.


See the results of smoothing your model by pressing Tab. If you’re not happy with some sharp angles, put more space in between the edges.
