Equipment Modelling in PDMS

To start with Equipment Modelling, you should go to Equipment Application.

How to go to Equipment Application
Go to Design Menu then select Equipment from drop down.

Modelling Equipment in PDMS
In PDMS, Equipment can be modelled in Two ways 

1. Using Primitives

2. Using Standard Equipment Template

Before creating equipment, you must be at zone level in hierarchy. Optionally under Equipment, Sub-Equipment (SUBE) can be created to classify different parts of Complex equipment, which gives user flexibility to work on specific parts in later stage.

Let's see First Method....

Equipment Modelling using Primitives.

In this Method, Equipment will be modelled using combination of Primitives, which are arranged in such a way that they physically model the real life object to some degree.

Primitives are nothing but basic geometric shapes which forms part of Equipment.

Geometry of Primitives is totally user defined, there is no link with Catalogue database.

Primitives can be modelled under Equipment and Sub-Equipment.

Here is list of all Primitives available in PDMS

1. BOX

2. CYLINDER

3. CONE

4. SNOUT

5. PYRAMID

6. CIRCULAR TORUS

7. RECTANGULAR TORUS

8. DISH

9. SLOPED CYLINDER

10. EXTRUSION

11. SOLID OF REVOLUTION

Nozzles also form part of Equipment Modelling,unlike Primitives, Nozzles can be directly selected from Catalogues Available in Project. Nozzles takes thickness, diameter and Bolt settings from catalogue while height needs to be entered by user.

It is Completely User judgement which kind of Primitive should be used to Model equipment.

In general, Primitives shall be selected in such way that Equipment modelling becomes easier to create or Modify.

We will see each primitive in Detail in next posts.....

Design Module

Design Module is Main constructor Module in which Complete Chemical Process Plant is 3D modelled. User selects required components from available specifications and catalogues and positions them as per engineering design. 3D model data is stored in Design database for individual site created. Design Module provides facility to check elements for Clashes, Reporting to produce various design documents for quality checks, Material Takeoff and Preview of Piping Isometrics.

In Design Module, all the Functions related to specific discipline are grouped under Applications such as Equipment, Pipework, etc. User need to Select appropriate Application in order to work, so that relevant Functions for particular discipline will be made available.

Applications in Design Module 

1. General
This Application Provides Functions which are common to All disciplines, such as Creation of Site/ Zone, Copying or Deleting Elements.

2. Equipment
This Application Provides Functions which are Useful for Equipment Modeling, such as to Create, Modify Equipment or Primitives.

3. Pipework
This Application Provides Functions which are Useful for Pipe Modeling, Such as to Create, Modify, Connect Pipe or Piping Components.

4. Cable Trays
This Application Provides Functions which are Useful for Cable Tray Modeling, Such as to Create, Modify Cable Trays.

5. HVAC Designer
This Application Provides Functions which are Useful for HVAC Modeling, Such as to Create, Modify HVAC and its Elements.

6. Structures
Structures has Four Applications which are as follows :
I. Beams and Columns 
Provides Functions to Create or Modify Sections

II. Panels and Plates
Provides Functions to Create or Modify Panels or Plates

III. Walls or Floors
Provides Functions to Create or Modify Walls or Floors

IV. Access, Stairs and Ladders
Provides Functions to Create or Modify Access, Stairs , Ladders

7. Design Template
This Application Provides Functions to Create PDMS Element using Standard Design Template which already created by Administrator.

8. Cabling System
This Application Provides Functions to Create CableWays, Cables, Assigning Cable Material for Cables.

Before User starts creating or modifying any element, User must have read-write access to that element. if access not provided, user must request administrator for the same.
Following command maybe useful to find out this :

Q DBWRITE

if True  -  User Has read-write access to Database
if False - User do not have write access, User should request access to Administrator
