Read the first 7 CAD & 3D Modeling for Piping flashcards as text

  1. In a 3D piping model, what does the term 'clash detection' refer to?

    Answer: Locating where two or more components physically overlap or interfere

    Clash detection identifies where components in a 3D model physically overlap or interfere, preventing costly field conflicts.

  2. Which file format is most commonly used for exchanging 3D piping models between different CAD platforms?

    Answer: STEP (.stp)

    STEP (Standard for the Exchange of Product model data) is the ISO standard neutral format widely used for 3D model exchange across platforms.

  3. What is the purpose of a 'P&ID import' function in a 3D piping CAD tool?

    Answer: To drive 3D model population and validation against the process design document

    Importing the P&ID into a 3D tool allows the software to validate that all instruments, valves, and lines in the model match the process design intent.

  4. In SmartPlant 3D or AVEVA E3D, what is a 'specification' (spec) used for?

    Answer: Restricting component selection to approved materials, ratings, and sizes

    A piping specification (spec) in intelligent 3D tools filters available components so designers can only select materials and ratings approved for each service.

  5. What does 'parametric modeling' mean in the context of 3D piping design?

    Answer: Creating geometry driven by editable parameters so changes propagate automatically

    Parametric modeling links geometry to parameters (diameter, length, rating) so changing a value automatically updates all related geometry.

  6. Which of the following best describes a 'line list' as it relates to 3D piping CAD?

    Answer: A tabular document listing each pipe line with its service, size, material, and design conditions

    A line list is a project document that catalogs each numbered pipe line with key engineering data used to drive spec and tag assignments in the model.

  7. In a 3D piping model, what is a 'nozzle' typically defined as?

    Answer: A connection point on equipment (vessels, pumps, heat exchangers) to which piping connects

    In 3D modeling, a nozzle is the modeled connection point on equipment that defines orientation, size, and rating where piping attaches.
