What can I round in SketchUp?

At the beginning let's think about what objects can be rounded in SketchUp.
We can split this into two categories:

  1. Solid objects (Groups or Components)
  2. Edges

To make it simpler let say that rounding of solid objects is a 3D operation. Where round edges of a face is a 2D operation, although faces in SketchUp are placed in the 3d space.

You can also round bunch of edges placed in the 3d space.

What can I use to round corners?

Depending on what is your goal you can use:

  1. SketchUp native tools
  2. Plugins for round Solid objects
  3. Extensions dedicated for round edges corners

SketchUp is simple but the magic is hidden in the knowledge of the native tools usage.
You can create a lot using only build in features. Rounding of corners can also be done in that way.

To make solid operations, specific extensions can be used. Most popular tools for that are: Fredo RoundCorner, FredoCorner and Bevel from mind.sight.studios.

When it comes to work with bunch of edges in space or as a part of faces you should definitely check sketchup round edges extension.

It is specially useful when you:

  1. work with 2d faces
  2. need to add specific arc between bunch of connected edges
  3. creating a solid object and would like to have full control of the process
