Tip - scenes

Like all the commands and dialogs in SketchUp, the Scenes are
multifaceted, and very powerful in controlling your display. Scenes form
the backbone of our display controls. You can save not only a snapshot of
the model but also the following:

1. Layer states : For example, we can have a Scene for the structural steel

layers, the process equipment layers, all layers, or just the new project
layers. This is done by selecting only the Layer property checkbox in the
Scene dialog box. Then, we set up these Scenes with names starting in “L-.”

2. Scene: As you create sections that help you see within a model, you

should save them as Scenes. We name these Scenes using names
starting with an “S-.” We typically create Scenes at every level and at
many column lines.

3. Shadows: For solar projects, we always set up Scene for December

22 at 9 am and 3 pm . Transitions between these two Scenes allow us to
determine if solar panels are ever shaded.

Step 3: Equipment Selection and
Process Finalization

Goals : To be specific, to quote and select the process equipment for the
project and to complete the SketchUp model.
Inputs : The approved PFDs and preliminary proposed model of the project.
Tools : SketchUp 7.1, LayOut 2.1, and a word-processing program.

We select equipment based on the client's selection of a final process.
To do this, we must specify the equipment and request quotations from
equipment manufacturers. We take our basic equipment models from the
SketchUp project model and import them into LayOut for dimensioning
and labeling. LayOut 2.1 introduces a Dimension tool. We use a word-
processing program to write up specification and equipment performance
standards and then combine the documents. These specification docu-
ments are sent to vendors for quotation.

Once the equipment has been selected, we use SketchUp again in approving
vendor drawings. We again model the equipment. This time, the modeling
is done in much greater detail. The modeling process provides us with much
greater understanding of the equipment than that obtained from simply
reviewing the drawings.

This process is done for all the equipment in a project until everything is
approved for fabrication and their fit in the model is verified.

This step includes all subcontractor work. Our subcontractors provide us with
drawings and models that we incorporate into our project model.
