Option Switch 8: Dimension Line Standout - Isogen - Reference

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
