PDMS guide | Beginners: Interface, Settings, Modeling and Drafting

1 Interface

To be able to login to PDMS, user needs to select 1) Project, 2) Facility, 3) Sub Facility, 4) User Role, 5) Module (Design, Draft, etc.) and 6) Databanks (Design, Draft, etc.), see picture 1 below.

1.2 Main Windows

PDMS interface consist of three main windows: Graphical Window, Command Window and Draw List Window, which are shown in pictures 2, 3 and 4.

Graphical window is the main window used to create, modify, delete and view model elements.

Command window is used to key on different type of PDMS commands, such as, query attributes, moving elements, etc. Note that these commands can be also accessed from menu.

Draw List window is used to access elements in database hierarchy. Current element is highlighted in Graphical Window. Elements can be added or removed from the main window with different colors.

1.3 Settings

Settings- menu can be used to change various settings, such as, default colors (picture 5), representation (picture 6), size of aid CE arrow and visible on/off, pline rules (picture 7), tolerances etc.

All changes made through Settings- menu are valid only for the current session.

2 Modeling


2.1 Section Modeling


2.1.1 Create Section


Sections can be modeled by using “Create > Sections > Straight”- function, see picture 10 below. Make sure that the default profile specification has been set.

Section can be positioned by using Position Control. The first point picked will be the start of the section and the second one the end point. Section should be modeled pointing to either to north or to east. After picking the points, press “Dismiss”.

Check off “Secondary Nodes”- option, if section is not to be connected.



– Use always “round” numbers, for example, 1968 instead of 1968.37 when creating or modifying sections for drafting purposes.

– After creating the very first section, double-check the position of it by querying the start and end positions (Q POSS POSE) and then confirming them.

2.1.2 Modify Specification and/or Justification

Section specification can be changed by using “Modify > Sections > Specification”- function, see picture 11 below.

Select section(s) to be modified by using CE, List or Pick- method. After selection, press “Apply” and “Dismiss”.



– Make sure that Justification and Member lines are set correctly. (Both should be the same).

2.1.3 Extend Section

Sections can be extended (trimmed) by using either one of the following functions:

1) “Position > Extend > Through” (explicitly)

– Select pline > Apply > Dismiss

2) “Position > Extend > By” (relatively)

– Key in positive or negative distance > Apply > Dismiss
