PLANT DESIGN SYSTEM (PDS) TUTORIAL
You have to do basic settings in Micro station. 1. Mouse button assignments
Reset button
Tentative or Snap button
Data or Accept button
2. ‘Key-in’ pallet
If you didn’t find ‘key-in’ pallet in PDS, Go to-Applications-Micro station-Utilities‘Key-in’. Then you will get this ‘key-in’ pallet. It is used to give alphanumerical. 3. Setting of windows
Similar to Micro station we can set up to 8 windows based on our requirement. Always try to work in plan, front, left or right views for better identification of snapping points. Practice Basic Micro-station commands like update all, zoom-in, zoom-out, zoom window area, fit all,pan,view previous, view next etc.
4. View concept:
View concept is very important for any modeling software. In Front view (Look North) we can see East-West, Up-Down directions but cannot see North-South directions. In Plan View (plan North) we can see East-West, North-South directions but cannot see Up- Down directions In Iso (Isometric) we can see all directions
How to start PDS: •
Select Pdshell ICON from your desktop or start, programs (Task bar).
•
Select project in which you have to work ( After using user id and password if necessary).
In PDS there are 16 modules. All are controlled by Project administrator. Some Basics modules: Equipment modeling Piping designer Isometric drawing manager Drawing manager Pipe support designer Frame works
-Modeling of Equipments. -Routing between Equipments. -Isogen or Output of line. -Annotation and labeling purpose -pipe supports -civil and structural
•
Select option of Equipment Modeling, again same for select design area.
•
Select design area in which you have to work
•
Select Model in which you have to work.
•
Then you will get below screen.
•
Setting of pallets on screen as per your requirements from menu bar.
Always try to open windows 5,6,7,8 against each of windows 1,2,3,4 and wise versa for viewing TEE (Primary & Secondary axis) orientation in two windows at a time. Set Isometric view, Plan view, Left view, Front view etc. in respective windows as per your requirements using respective icons from viewing direction pallet.
Secondary axis
Primary axis
Place point
EQUIPMENT MODELING
Basically there are two ways of placing equipments i.e. Primitives and Parametric in which parametric shapes are usually used which is a good practice.
Primitives: Primitives are pre-defined 3D-Solids like cylinder, cones, dish and box. • •
Select Start from equipment manipulation pallet. Select parametric help icon.
Here you will get standard equipments like pump, exchangers, vertical and horizontal vessel, platforms, ladders, handrail etc. We can modify “equipments “as per client specification.

Let’s start with Complex vert cyl equip ( Tower or Vertical vessel ). Fill the form with values mentioned in the given sketch.

For any vertical equipments primary axis should be UP and secondary should be NORTH. And for any horizontal equipments primary axis should be PARALLEL to equipment axis and secondary should be UP for getting proper nozzle orientation. Here +E1, +E2 and +E3 indicates the types of heads (Dish-Ends)
NOZZLE MANIPULATION
Lets try to place below shown M1 nozzle on Complex vert cyl equip ( Tower or Vertical vessel ).

Fill the form as per Nozzle list and then select ACCEPT/RETURN icon.
You’ll found nozzle M1 added to your nozzle directory as shown.
Blind Flange For placing blind flange on M1 nozzle.
