Planning pharma and food plants with AutoCAD Plant 3D
Stainless steel, aseptic connections and slope down to the drain: in pharma and food plants, every line must be drainable and properly documented. With suitable piping specs and a checked template you model this in AutoCAD Plant 3D.
With us you will find solutions for your tasks.
Typical plants
- Active ingredient and fine chemicals plants
- Process and clean media plants (water, steam, gases)
- Dairy, brewery and beverages
- Supply of food production sites with steam, refrigeration and compressed air
Typical planning tasks
- Stainless steel piping specsPipes, fittings, aseptic and clamp connections in one piping spec – with material number and ordering text.
- Slope and drainabilityRoute lines with a slope and show the slope correctly on the isometric.
- Document weldsWeld list and bill of materials from the model – as a basis for fabrication and qualification.
- Extend the existing plantProduction running, cramped plant rooms: capture the existing plant by laser scan and continue planning on it.

A selection for orientation. Which regulations apply is determined by your project, your client and the permit. The short descriptions do not replace the standard.
Piping specs and catalogs
For pharma and food plants, the stainless steel catalogs are particularly suitable – including aseptic components and press fittings – as well as valves and instruments:
- Stainless steel – pipes & fittings – 5 catalogs
- Valves (DIN EN) – 12 catalogs
- Instruments (I&C) – 2 catalogs
All catalogs with contents: ASEING Piping Catalogs. Your own piping spec? Size it in the Piping Spec Calculator – preliminary sizing, not a piping design. Existing catalogs are checked by the Catalog Checker.

Questions from practice in training and support
- The slope triangle is dimensioned incorrectly on the isometric To the practice question
- The material number appears on the isometric as a number (14571.00 instead of 1.45711.4xxx – Material number, stainless steel Material number according to DIN EN 10027-2. Numbers 1.4xxx are stainless steels, e.g. 1.4301, 1.4404 or 1.4571. Background and sources ›) To the practice question
- The wall thickness shows “Varies” although a value is entered To the practice question
- Edit ordering texts and wall thicknesses in Excel and import them back To the practice question

Frequently asked questions
Can AutoCAD Plant 3D handle aseptic and clamp connections?
Yes, if the components are in the catalog and the connections are set up in the piping spec. The ASEING catalog “Aseptic components” contains aseptic connections, fittings, flanges and gaskets.
How do I model slope in AutoCAD Plant 3D?
You route the line with a slope; AutoCAD Plant 3D shows it on the isometric as a slope triangle. How the dimensions appear there is set in the iso style.
Does the model replace qualification?
No. The model, bills of materials and weld lists are a basis for the documentation. Qualification and validation remain the responsibility of the operator.
