You now should have submodel files in the folder you specified in the
earlier steps. Repeat the steps until the main model is totally divided into
comprehensive submodels (components) and no free entities or groups are
left in the main model.
Step 4: Editing Component Definitions in Submodels
Goals
: Edit entities in submodels and modify component definitions.
Inputs
: Component files (submodels) created in the previous step.
Tool
: SketchUp's component instances.
Now you have several submodel files that are generated from the main-
model file. Whether it is a piece of furniture, a floor of a building, a whole
building, or a city block, try to break the main model completely into
comprehensive design units.
Info
When you open one of the submodel files they do not appear to be
components; there is no bounding box around the entities. This is because
you are already inside the component when they are opened; in other
words, changing anything in the submodels means that you are modifying
the component definitions.
The submodels created are just like any other components, and there is no
special knowledge required to edit these. You can push-pull faces, add details,
or apply textures to objects.
Attention
The only restriction of submodel editing is that in submodels, you
should not change the general positional relation of objects to their
SketchUp axis.
In the same way, you should not redefine SketchUp's axes and change their
original position in submodels. SketchUp's axes in submodels corresponds
to the component's axes of that component. Its position in the main model
is registered by the position of the component's axes to the original position
of main-model SketchUp axes; therefore, changing their positions will force
them to be positioned wrongly when reloaded (the next step). On the other
hand, changing the axes of the main model does not affect the positions of
components within the file.
