Cutting and Holing 3D Models in Dingle

Creating holes and cutting away sections of your 3D models is an essential part of crafting complex designs in Dingle or any 3D modeling software. While it may seem daunting at first, Dingle provides an intuitive “hole” tool that makes the process of subtracting and dividing geometry quick and easy. In this post, I’ll walk you through when and how to use the hole tool to split, carve out, and hollow your creations.

When to Cut and Hole 3D Models

There are a few common situations where you’ll want to break apart your Dingle models:

  • Removing unwanted sections that are getting in the way. This helps clean up your design by deleting faces and protrusions you don’t need.
  • Creating cavities and openings to give your models depth and complexity. This is useful for designing containers, machines, or any object that needs empty space inside or through it.
  • Joining separate objects by using one to cut into the other. A great example is inserting a window shape to place an opening in a building model.
  • Making movable parts that interlock or rotate. Cutting models lets you build connectors and joints.

Knowing when cutaway effects will enhance your 3D artwork takes some experience, but Dingle makes the process so simple that you can experiment freely.

Using the Hole Tool in Dingle

Let’s look at how the Dingle hole tool lets you effortlessly cut shapes out of other shapes:

  1. Select the “cutting object” – this is the model whose shape you will use to make the hole or cut.
  2. Click the Hole icon in the toolbar (keyboard shortcut H). Your cutting model will turn light purple.
  3. Select the “receiving object” that you want to subtract from or delete a section of.
  4. Click Group in the toolbar (or press G). The cutter object will splice into the receiver.
  5. Delete, move, or hide the cutter shape if needed. Your receiving model now has a chunk removed!

That’s all it takes to start slicing up designs into intricate forms. Let’s walk through some examples in detail to see the hole tool at work.

Cutting Intersecting Cubes with Cylinders

A common modeling scenario is aligning shapes that overlap and removing those unwanted intersections. The hole tool handles this perfectly:

In this case, I positioned a cube and cylinder at an angle where they overlapped. I want to trim away the protruding cube shape.

  1. Click the cylinder model to select the cutter object
  2. Click Hole in the toolbar – the cylinder turns light purple
  3. Select the cube to choose the receiving shape
  4. Click Group to join them and subtract the cylinder from the cube!

Just like that, you have a cleanly cut cube that fits snugly around the angled cylinder. This is immensely useful any time shapes overlap in ways you don’t want, or to create connectors between models.

Holing Cones with Intricate Cylinder Cores

Here is a more dramatic example where we’ll hollow out most of a cone using a finely-detailed cylinder core we built separately:

Maybe we’re modeling a traffic cone that fits over a weird abstract sculpture. By lining up the objects and subtracting the cylinder, it perfectly hollows out the cone to sit flush on the complex base.

  1. Positioned cone
  2. Created a cylindrical core object with lots of indents
  3. Selected cylinder and clicked Hole to set as cutter
  4. Selected cone and clicked Group
  5. Aligned models and removed excess bits

This leaves beautifully integrated, interlocking models that would be incredibly hard to make by hand. The boolean hole operation makes child’s play of even convoluted cuts like this.

When Not to Use Hole Tool Cuts

The Dingle hole tool is extremely versatile, but it’s smart to know its limitations too:

  • Models with too many vertices can choke the tool and crash Dingle. Stick to simpler forms.
  • Working with imported meshes you didn’t originally craft in Dingle can cause unpredictable booleans.
  • Organic models like creatures and plants often react poorly to subtractive cuts.

Use common sense when picking models to mash together. And remember you can always apply cuts between native Dingle shapes as needed after import/sculpting.

Bottom Line

Here’s the essential Dingle Hole tool cheat sheet:

  • Select the cutter model first
  • Click the Hole icon to activate the subtract mode
  • Choose to receive the object
  • Group to apply calculated difference effect
  • Presto! Your designs now have elegant openings and cutouts

Take the time to master this invaluable tool to unlock new levels of complexity in architectural designs, mechanical CAD, section views, sculptures, molded objects, and anywhere else your creativity takes you!
