Controls the plotted leg lengths of elbows and fitting tees and crosses, and keeps the pipe length scaling proportional to the true length. This leg length control facility does not apply to fabricated (pulled) bends or set-on (stub-in) tees or crosses. Different connection leg depictions are allowed with multi-port components. You can display valve and instrument spindles in either flat or isometric projection.

Use the plotted leg length control with care. Long leg lengths take up more space on the drawing and can sometimes have an adverse effect on the finished isometric. The maximum value allowed is 18 mm, and the minimum value allowed is 6 mm.

Switch Settings

The following settings are available for Option Switch 95:

SWITCH POSITION 1

0

Set the standard leg length of 9 mm. This is the default setting.

SWITCH POSITION 2

Value

Set the required leg length in whole mm. For example, enter 12 for a leg length of 12 mm.

SWITCH POSITION 3

0

Use normal pipe scaling to determine pipe lengths.

1

Scale pipe lengths proportionally to actual true lengths.

SWITCH POSITION 4

0

Reserved

SWITCH POSITION 5

0

Use dotted connection lines on all multi-port fittings.

1

Generate dotted connection lines only when necessary for picture clarification, for example, where two or more ports are positioned on the same side with attached pipework running parallel to each other.

2

Do not show dotted connection lines.

SWITCH POSITION 6 - Orientation of Valve and Instrument Spindles

0

Show valve and instrument spindles as flat.

1

Show valve and instrument spindles in isometric projection.

SWITCH POSITION 7 - Display of Continuation Components at Split Points

0

Show the entire continuation component from the next sheet for bends, elbows, tees, and crosses. Show a single leg for all other component types. This is the default setting.

1

Show one leg as continuation for any component.
