Components

SketchUp Components are the basic building blocks used by OpenCutList to build a Parts List.

From Components to Parts

To ensure the most meaningful results, several assumptions have been made while developing OpenCutList. It is essential to follow these guidelines for best results:

  • Use components for modeling your project (scaled components are also supported), because only components will appear in the Part List. They may be nested in groups and even inside other components.

  • Label the definition and the instance of your components (optional). This information will appear in the Part List.

  • Correctly define the component axes to match the grain direction and/or the orientation of the part in the raw material. Usually length, width and thickness cannot be swapped in wood.

  • Apply SketchUp material to your components and configure its parameters through the Materials tab.

Bounding Box and Dimensions

OpenCutList uses the blue bounding box of a component (provided by Sketchup itself) to compute its length, width and thickness. This is done irrespective of whether the component has an irregular shape, holes, etc. (of course, there are some limitations to this approach). In the following example, OpenCutList will see the box below as a rectangular box, not considering the miter.

A component as seen by OpenCutList

By default, OpenCutList will consider the largest dimension of the component as the length, the shortest dimension as the thickness, and the last dimension as the width. This behavior can be changed on per-part basis.

It is also possible to configure OpenCutList so that it will never guess the dimensions, but always consider the dimension along the local red axis as length, the green axis as width, and the blue axis as thickness.

OpenCutList does not consider components with zero volume. Components must be Solid Components in SketchUp.
