This workflow can be used to replace a placeholder component with a component added to a spec.
To modify piping components in a spec
Add and Remove Component Sizes in a Spec. Set Component Properties in the Spec. Update a spec with the changes made to the catalogs.
To add piping components from a catalog
Add a component to a spec that is currently a placeholder in the model. You can also modify an existing component in the spec.
To convert a block to a block based component
Assign one or more piping connection ports to AutoCAD blocks. Save the drawing that contains the custom piping component block definitions.
To create instrumentation and custom components
Substitute placeholder piping components in the model with a compatible component in the spec. You can create and add parts to a pipe line that are not in the pipe spec.
