Deliverables
What we produce in CADWorx
Spec-driven modelling means the model knows what it is made of. Pick a line number and the wall thickness, rating, material and bolt set come with it — so isometrics and MTOs are generated, not drafted.
Scope your deliverablesSpec-driven 3D piping model
Every component placed from the project piping class, so the model carries rating, schedule, material and end preparation throughout.
Automatic ISOGEN isometrics
Fabrication and erection isometrics generated from the model with field welds, spool breaks, bolt lists and a material take-off on every sheet.
Piping GAs, plans & sections
Plot plans, equipment layouts, plan and section drawings with elevations, tie-in points and nozzle orientation marked.
Clash-free coordinated model
Checked against steel, equipment, civil and electrical models in Navisworks, with access, maintenance and insulation envelopes respected.
MTO & line schedules
Material take-off by line, area and spec straight from the model, plus line list, valve list and tie-in schedules exported to Excel.
Stress & support hand-off
PCF exports to CAESAR II on every critical line, with support locations fed back into the model once the stress run settles.
Interoperability
CADWorx file formats we work with
CADWorx runs on AutoCAD, so it talks to everything on site — and its PCF output is what makes the stress and isometric workflow automatic rather than manual.
| Format | Direction | How we use it |
|---|---|---|
| PCF | We deliver | Line-by-line export driving ISOGEN isometrics and the CAESAR II stress model from one source of truth. |
| DWG / DXF | Both ways | P&IDs, plot plans and vendor drawings in; model drawings, GAs and isometrics out in native AutoCAD. |
| NWC / NWD | We deliver | Published to Navisworks for federated clash detection and construction review. |
| Point cloud (RCP / RCS) | We import | Laser-scan data for brownfield tie-ins, so new routing fits the plant that actually exists. |
| STEP / equipment models | We import | Vendor pumps, exchangers and packages placed as real geometry with correct nozzle locations. |
| Excel / CSV | Both ways | Line lists in to drive modelling; MTO, valve and tie-in schedules out for procurement. |
| IFC | Both ways | Exchange with structural and building models where the project runs an open-BIM workflow. |

How we work
Our CADWorx workflow
Our process is built around catching problems before they reach your reviewer, so the checking stages are fixed, not optional.
- 1
P&ID & plot plan review
Line numbers, specs, insulation, slope and criticality extracted from the P&IDs and reconciled against the plot plan before modelling.
- 2
Spec & catalogue setup
Piping classes built or validated in the Spec Editor so every component placed is a procurable item, not a generic fitting.
- 3
Equipment & nozzle placement
Vendor equipment positioned to the plot plan with verified nozzle orientation, maintenance access and dropout areas.
- 4
Routing by line number
Lines routed for process requirement, supportability, flexibility and operability — valves reachable, instruments readable, drains at low points.
- 5
Clash & constructability review
Quality gateNavisworks clash cycle against steel, civil, HVAC and electrical, plus a walk-through for access, lifting and maintenance.
- 6
Stress loop
PCF to CAESAR II for critical lines; supports, loops and anchor positions fed back into the model and re-checked.
- 7
Isometrics, MTO & issue
ISOGEN isometrics generated, checked sheet by sheet, and issued with the MTO, line list and coordination model.
One stage is a formal quality gate — work does not move forward until a senior engineer signs it off, which is why revisions after issue stay rare.
Choosing a platform
When CADWorx is the right choice
The right software is the one that produces your deliverable with the least rework downstream. This is the call we would make on your scope.
Choose CADWorx when
- Process plant piping where a piping class library has to govern every component placed.
- Isometrics and MTOs are needed in volume and must regenerate cleanly after every model revision.
- The team already works in AutoCAD and wants plant intelligence without a new platform and database to administer.
- Stress analysis is in scope and you want the CAESAR II model built from the same geometry as the isometrics.
We would use something else when
Still unsure? Send the drawings and the deliverable you need — we will tell you which platform we would run it on, and why, before quoting.
