Learn how to utilize the Sculpt workspace in Fusion to build a lampshade component for a lamp model. This tutorial guides you through every step of the process, from isolating specific components, selecting the appropriate plane, applying circular symmetry, and adjusting the form to ensure the lampshade fits appropriately.
Key Insights
- The Sculpt workspace in Fusion allows for the creation of complex components such as a lampshade by isolating individual elements and applying symmetry to ensure consistency.
- It's crucial to adjust the size and position of the lampshade in relation to other components such as the lampshade arm and the washer to achieve a realistic and functional model.
- When modeling in T-spline, care should be taken to avoid twisting the edges, as it could result in the form folding over itself, disrupting the model's integrity.
In this video, we will use the Sculpt workspace to build the lampshade for our lamp. I will scroll down in my data panel and open up Step 7, T-Spline Modeling.
When your file is open, you can close your data panel and let's begin. The first thing I would like to do is go right-click, New Component, and I will name this component Lampshade. Before I begin to model my lampshade, I would like to hide specific components to make it easier for me when I am modeling my lampshade.
I will unroll the import assembly and the arm assembly, and I will select Holding Control, the lampshade arm, lampshade, and rubber washer. Right-click, Isolate. In Fusion, we can isolate and un-isolate specific components instead of hiding individual components.
Notice that when I do an isolate, the rest of the components that were not selected have automatically been hidden. I can collapse these two components, and we can begin to model our lampshade. I will orbit so that I am looking at the bottom of my rubber washer, and I will go Create Form.
For our lampshade, go to the Create, drop-down, and find Cylinder. Just like when making solid modeling geometry, we need to select a plane. I will select the underside of my washer, and then find the center point of the circle, and click.

Don't worry about your size, we will change that in a minute. I will change the diameter to 30, the height to 150, and I will leave my diameter faces at 8, and I will change my height faces to 3. Before we hit OK, make sure to change your symmetry to Circular. We can apply our symmetry after we create our form, but it is easier to create it at the beginning.
I will hit OK, and now we can begin to edit our form. Notice that all of the vertical edges in my model are green, and this is because it has applied circular symmetry. We can go Edit Form, and begin to form our lampshade.
I will drag this out 60 millimeters to get the correct base size, and then I will go to the front view on my view cube, and begin to model more free form. You can see that I have left the lampshade arm on, and the washer on, so that I can get a good feel for how my lampshade should fit in between these arms. I'm going to leave a small gap on both sides, and when I am done, hit OK.
We can now see that our T-spline model is modeled and shaped the correct way, so whenever you are done placing your lampshade, hit Finish Form. One word of warning, if I select this point, right-click Edit Form, and move it in this direction, the lampshade will move outwards in the correct fashion, because it is symmetrical about the center, but my edges will twist. This is not a good workflow when working in T-spline modeling.
It increases the risk of our form folding over itself. If I hit OK, and go to Display Mode, Box, we can see that we have twisted our lampshade into this weird shape. I will hit Control-Z to undo, and this is what it looked like before.
If I go back to Display Mode, and toggle Control-Frame Display, we can see that our box and our lampshade are in appropriate shape. I will hit OK, and Finish Form. I will right-click on my lampshade, and go Unisolate.
I will activate my top component, and save my file. If we open our lampshade component, we will see that we have created a surface. This surface has no thickness, so in the next video, we will need to apply a thickness to our model.
I will see you in the next video.
