To use an existing cost model, load it in the Cost Estimator tab in the tabular area for the active drawing. When you open a project or are in the process of creating one, by default the last used cost model is loaded. To load a different one, follow the procedure below.
To load a cost model
The cost model is loaded for the active drawing and can be used or edited.
IMPORTANT: Before loading a cost model in an actual project, make sure you have set a location where the parameter value modifications that you make during your work will be saved. Setting such a location allows you to use your modified data the next time you open the project. Modifying cost model data in a project does not affect a cost model's default parameter values; the next time you load the cost model into a project, you will see the default values.
