Preface

Preface



S E C T I O N 1

ISOGEN contains a large number of variable features, such as isometric type and drawing size, dimensional units, line weight, BOM position on the isometric drawing, and so forth. These and other features are controlled by user-defined option switch settings. A total of 140 option switches are available, many of which have several positions or settings.

Option switches give you a high level of configuration that allows you to tailor both drawings and material lists to your exact needs, including control of:

Isometric type Fabrication and construction; fabrication only; construction only; individual spool isometrics; multi-pipeline system isometrics

Graphic output options DXF, DWG

Drawing size Metric A series, American ANSI sizes, or special sizes

Viewpoint orientation Indicated by a north arrow

Dimensions Standard string, overall, pipe supports, and to valve centers

Drawing frame User-designed or standard

Text Large, medium, and small

For many option switches, a switch detail sheet is available in the Appendix of this document. The switch detail sheet provides additional information regarding how a specific option switch setting impacts isometric drawing output. If a detail sheet is available, it is listed under Option Switch Detail Sheet.at the end of the option switch topic:

Option Switch 2: Cut Piece Numbering/List Type Controls the generation of the cut piece list and corresponding cut piece identifiers (numbers or letters) at appropriate positions along the plotted pipeline. An option to have cut piece identifiers (numbers or letters) starting at 1 or A on each isometric drawing as opposed to each pipeline is also controlled with this option switch.

Cut piece numbers can be output on the isometric drawing in a variety of alternative enclosure types which are controlled by switch positions 7 and 8.

There are two types of cut piece lists: the old style, which has limited information, and the new style, which has full information.

Finally, when using imperial units you have an option to list the cut lengths on the new style cut piece list in a decimal inches format. This option is in addition to the regular value in the LENGTH column.

Option Switch 6: Date Output Controls the date format that is output on the isometric drawing and printed listings in a 2- or 4-digit year format. By default, the actual date that the software outputs is taken from either the PDF (pipeline data file) that is created by the host 3D design software or the computer system at the time the drawing is generated.

There are three format options plus an option switch setting to suppress any date output, even though a date exists in the IDF.

Switch Settings


SWITCH POSITIONS 1 and 2 - Date Output and Format

0 1 2 3 10 11 12

Option Switch 7: Pipeline Splitting (User Control) Identifies the method used when splitting two pipelines into multiple isometric drawings. Two methods are available:

Automatic: This method automatically calculates the number of pipeline graphics that can be displayed on the selected drawing size, and then generates the exact number of isometric drawings that are required to contain the completed pipeline.

Fixed: This method requires that you specify the number of isometric drawings that are necessary to display the completed pipeline.

The setting in Position 1 is ignored if manual pipeline split points are present in the piping data file (PDF).

Since any option switch setting applies to all the pipelines in a run, it is recommended that you only use the fixed method in special cases for single pipeline runs.

An added option permits any drawing split points input in the 3D model by the user and present in the PDF to be ignored.

Switch Settings


SWITCH POSITIONS 1 and 2 - Various Controls

0 Value

Use automatic splitting to control the number of isometric drawings that are required. Set the number of isometric drawings that are required.

Option Switch 8: Dimension Line Standout Controls dimension line standout distances for the following:

String and composite dimensions that are normally plotted as the middle layer of multi-layer dimensions.

Dimensioned messages, support messages, and reference dimensions on the inner layer, but only when a standout distance in Option Switch 40 is not set.

Overall dimensions on the outer layer, but only when a standout distance in Option Switch 118 is not set.

Values that are less than or equal to 11mm are ignored by the software and substituted by the appropriate standard dimension line standout distance. When the option switch value is greater than 11mm, the software uses that value to set the dimension line standout distance for string and composite dimensions on the middle layer. The inner dimensioned layer for dimensioned messages, support messages, and reference dimensions are then set to be 0.5 times this distance, while the outer layer overall dimensions are set to 1.5 times this distance.

Dimension text and messages are placed along a section of pipe in isometric projection (oblique angle or slanted text).

This feature is only available for DXF format output styles generated using the piping object data (POD) interface.

Text oblique angle is adjusted to be parallel to the dimension standout direction.

When it is practical to do so, ISOGEN attempts to set a vertical dimension standout for horizontal sections of pipeline

Switch Settings


0 Value

Plot standard dimension line standouts. This is the default setting. Set the required standout distance (in whole millimeters), for string and composite dimensions on the middle layer.

The standard dimension line standout distances for the various drawing sizes are as follows:

Small-sized drawing text (Option Switch 4, Position 1)

String/composite dimension standout - 12mm.

Messages, support and reference dimension standout - 6mm.

Overall dimension standout - 18mm.

Medium-sized drawing text (Option Switch 4, Position 0)


Message, support and reference dimension standout - 7mm.

Overall dimension standout - 21mm

Large-sized drawing text (Option Switch 4, Position 2)

Option Switch 32: Drawing Output (Scaling) Allows the increase or decrease of the final plotted isometric size, and thus changes it from what is defined by Option Switches 14, 15, and 16.

Switch Settings


0 to 100 Value

Allows no change in scaling and generates an isometric drawing at the size defined either by Option Switch 14 or by a combination of Option Switches 15 and 16. Increases or decreases the final isometric size in the ratio of Value/100. For example, a value of 71 generates a drawing at 71% of the original size; a value of 120 generates a drawing at 120% of the original size.

Option Switch 34: Drawing Output (Picture Scale) Increases or decreases the scale of the pipeline picture part of the isometric drawing, while leaving the other parts, such as the drawing frame, material list, title block, and line summary areas, unaltered.

When you use this option switch, the whole of the pipeline picture and all text pointing to it may be re-scaled to make it larger or smaller.

Switch Settings


0 or 100 Value

Use normal picture scaling (100%). This is the default setting. Increases or decreases the scaling effect by the amount specified. For example, a value of 71 reduces the size of the drawing 71% of its original size.

Option Switch 35: Drawing (Reserved Areas) Creates two reserved areas across the bottom of the isometric drawing. One area stretches across the bottom part of the drawing region, while the other area stretches across the bottom of the material list. Once set, both areas are reserved on the drawing frame for related project/pipeline information, and ISOGEN does not automatically plot any information in either area.

You can use the frame text positioning facility to add information that is included in the pipeline input data file in these areas.

Switch Settings


SWITCH POSITIONS 1, 2, & 3 - Reserved Area within the Drawing Region

0 Value

Allow no reserved area. This is the default setting. Reserve an area equal to the depth of the required area along the bottom of the isometric drawing as specified, measured in whole millimeters up from the outer line of the drawing frame.
