Piping or not piping
This is the question
Prepared by Michal Mlynarcik

Questions
• Do you need it?
• Is it what you think it is?
• Are you willing to spend resources on it?
• Is there an alternative?

Needs
General space reservationo Create object which represents a
“space reservation” for one or multiple pipes, flexible, conveyer belts, walk ways, cable trays, cables, cable bundles, wires, beam pipes etc.
Piping Designo Creates object representation of
single route of a pipe transporting fluid
Michal Mlynarcik
Needs
General space reservationo Cross-section shape of the space
reservation may vary, is freely adjustable or exchangeable
Piping Designo One circular cross-section type of
a pipe with predefined standard diameters and bending rules
Michal Mlynarcik
Needs
General space reservationo Geometry representing
connected objects do not have to be predefined standard parts from a catalog and the assisted part placement mechanism is not defined
Piping Designo Placement of pipe parts and
standard parts according to methodology. Placement of valve parts only from dedicated catalogue
Michal Mlynarcik
Needs
General space reservationo No need for multiple
representationso Not to be integrated with any
other specialized workbench
Piping Designo Special valve parts with multiple
representationso Close integration with HVAC and
Equipment Arrangement workbench
Michal Mlynarcik
Needs
General space reservationo Eligible: pure mechanical
assembly, electrical models, integration models, any “fluid transportation” unrelated field
Piping Designo Eligible: cooling/heating
networks, hydraulic networks, fluid transportation pipes

Comparison example
Piping workbench• Special interface• Special training needed• Pipe diameters predefined• Only circular pipe section• Routing of runs• Predefined parts from catalog• Build in intelligence restrictions
and selection rules• Multiple representation of piping
parts• Insulation management
Part/Assembly workbench• Familiar interface• Regular or no training needed• Any size possible• Any section possible• Routing of 3D splines• Any parts• No intelligence rules or
restrictions• Part also can have multiple
representations• Manual insulation

Piping Workbench restrictions
Different interface from any workbench in CATIA Specialized training needed to work effectively Limited to predefined diameter of pipes Placemat of pipe part needed to receive full advantage of the workbench The ‘route’ of the pipe will be always assembled from straight sections and elbows
with diameter (not a spline or 3D curve) Only 1 circular section type of pipe profile available The workbench does not support constraints, the runs(pipes) are referenced to
absolute 0 of the product The pipe is not shown as hollow object (unlike real pipe) The placing of valves (piping parts) is managed by catalogue with limited content
(now only parts created by CV) The creation of parts must strictly follow dedicated methodology and will undergo
verification by CAD Support (not a simple CATPart) Limited support after November 2013

Alternatives
Part design– Ask us for Power Copy and knowledge templates help– Supported by CAD Support Service
If you insist: System Routing workbench– Routing of runs– Limited number of cross-section types– No part placement from workbench catalog catalog disabled– Unsupported
Or: Systems Space reservation– Routing of path reservation objects– Placing of item reservation objects “cubes”– No part placement from workbench catalog catalog disabled– Unsupported
There no other similar Equipment & Systems workbenches fully configured for now (HVAC and Equipment Arrangement coming in 2013)

Conclusions
If you still think Piping Design workbench is suitable for YOU then: Contact CAD Support service for further information– Dedicated work methodology is developed and available– Supported by CAD Support service– Is actively used by EN\CV-DOW which helped a lot to implement it
It is a highly specialized workbench, which is very useful if you use it correctly and in its scope.
