You will need to open the latest version of Roblox Studio on a blank baseplate. Optionally, you can also download the needed plugins here:

One of the best use cases for solid modeling tools is that they provide you with the ability to quickly cut shapes and holes in any primitive part. To demonstrate this, we will create a sink with a faucet. However, rather than building around the sink extruded into the countertop, we will use the Negate and Union functions to cut a hole that is the shape and size of our sink.

How to do it…

We will begin by creating a simple sink cabinet and countertop using square parts. Then, we will create the shape of the sink and Negate a slightly smaller part inside of the sink, allowing us to create a hollow sink once we Union the two parts together. We will then position the sink, and use another negated part to create a pocket for the sink to sit in on the counter. We will then finish off by building a faucet. To do so, follow these steps:

1. Insert a square part on top of the baseplate.
2. Rescale the part to be the size of your desired cabinet, which we...

Smooth modeling tools are very useful for creating intricate shapes that would otherwise not be possible to make with regular primitive parts. In the following recipe, we will examine how to efficiently turn a sphere part into a bowl, and then we will use cylinder parts to fill the bowl with milk and create our pieces of cereal to fill the bowl with.

How to do it…

We will first create the bowl by negating a slightly smaller sphere inside of itself and using a square negated part, running through the middle of the sphere, to cut open the top, giving us the shape of our bowl. Then, we will place a cylindrical part representing the milk inside the bowl, scaling it to fit, and then we will create looped bits of cereal to fill the bowl with. To do this, follow these steps:

1. Insert a sphere part onto the baseplate where you want to build your bowl.
2. Rescale the sphere to make it larger and easier to work with, to a size such as 14, 14, and...

Detailing can be tricky, especially when you’re trying to engrave small details across a large area of parts. In this recipe, we will examine the step-by-step method to accurately transcribe details and even carve out a whole cylindrical set of stairs, leading from the center of what was a square block. By the end of this recipe, you will be left with a deeper understanding of how you can use the smooth surface modeling tools to heighten the level of detail in your builds.

How to do it…

We will first insert and rescale a square part to our desired size. Next, we will stack cylinders on top of one another, making the one above 2 studs wider than the one below it. After negating the cylinders and unioning them to the square base, we will create a border and details on the top surface of the platform. Lastly, we will move the detail pieces down until they extrude into the ground part, so when we negate and union the cylinders to the...

A great way to speed up your building and solid modeling process is to build the shape that you want to cut out separately from the part that you’re cutting from. This recipe will demonstrate a way of mastering this technique by first building a wall, and then building the arched shape of the separate entrance. We will then use the Negate and Union functions to carve our desired shape. Let’s see how we can do so next.

How to do it…

We will create a flat wall and then create the shape of the arch entrance using a square and cylinder part, rescaling the parts to extend them through both sides of the wall. Then, we will negate the entrance parts and union them into the wall, giving us our arch. To do so, follow these steps:

1. Begin by inserting a square block part into the baseplate.
2. Rescale the square part to be roughly 27, 34.5, and 3.75 studs. This will be the wall that we will cut the archway into.
3. Next, duplicate the wall...

In this recipe, we will examine the newly introduced Intersection tool, now available in the latest version of Roblox Studio. Unlike what happens when you union a negated part, where it cuts the shape out of the other block, the intersect tool instead takes the multiple overlapping parts and produces the shape of the inside volume, where all the parts overlap. We will use the Intersection tool to create the shape of a hole, which we will then attach to a brick wall, making it appear old or damaged.

How to do it…

After building a wall, we will add a top cap as well as side pillars to help define the wall. We will then create the shape of the hole on the front face of the wall and union the parts of the hole together. We will then duplicate both the wall and hole part, so we can use the intersect tool to create a solid hole piece. Then, we will duplicate the newly created hole piece so that we can negate and union it to the original wall, creating...

In this recipe, we will be examining a way to turn a standard square block and sculpt it into a low-poly styled rock. Just as we cut a hole through the block by unioning a negated part to a normal part in the Carving out Holes recipe, we will use the same method to shave chunks off the block until we are satisfied with the look of our stone.

How to do it…

We will begin by creating a large generic base shape for our rock. We will then position several negated parts, rotated at various degrees and angles throughout the base rock part. We will then union the negated pieces with the original rock, giving us our low-poly look. To do this, follow these steps:

1. Insert a part, preferably a square one, into the Workspace. This will be the rock base shape.
2. Rescale the part to make it into your desired shape. For this example, I am creating a tall rock with a size of 27, 41, and 25 studs. Remember that the inserted part can easily be rescaled later,...
