To Assign Insulation to Part of a Pipeline
1. Select the active assembly that contains the pipeline that you want to partially insulate.
2. Click Insulation. The Create Insulation dialog box opens. The Start option under Insulation Segment Points is selected by default.
3. Follow these steps to select insulation start and end points. Start and end points must be on the same pipeline:
a. Under Select Start Point, click and select a pipe segment to specify the insulation start point. Crosshair indicate the start point on the pipe segment, and the pipe segment ID is displayed in the Select Start Point box.
b. Click End under Insulation Segment Points.
c. Under Select End Point, click and select the insulation end point. Crosshair indicate the end point on the pipe segment, and the pipe segment ID is displayed in the Select End Point box.
4. Under Dimension, select one of the following to specify both start and end point placement.
 
* You must select Start and End under Insulation Segment Points to place the appropriate points.
—Specifies the distance of the start or end point from the pipe segment's upstream end.
—Specifies the distance ratio of the start or end point from the pipe segment's upstream end.
 
* In the above two cases, the reference location is from the start end of the pipe segment by default. Click to flip the location to reference to the end of the pipe segment. changes to to indicate the change in the reference location.
—Places a start or end point on the pipe segment perpendicular to that pipe segment.
 
* The pipe segment's start point must be perpendicular to the pipe segment's end point to make this option available.
—Places a start or end point from a specified datum plane. The datum plane must be perpendicular to the start or end point pipe segment. Piping creates a reference to the datum plane.
—Places a start or end point from a specified fitting. The selected fitting must exist in the same pipeline and in the same straight pipe piece. Click to flip the reference port.
5. Under Dimension, specify the point location parameters based on the selected placement option. Use the thumb wheel to move the point placement or enter a value in the thumb wheel box for exact placement.
If you clicked, , select a datum plane from the graphics window. Piping displays the datum plane name in the box under Dimension.
6. Under Insulation Parameters, select an insulation code to assign insulation between the specified placement points.
7. Click OK to assign the insulation to the pipe segment.
 
The following Specification Database files must be populated with insulation data in order to assign insulation to spec-driven pipelines:
The Insulation Directory file (Project Data file) must contain records for the insulation codes.
The Insulation MCAT file (Master Catalog file) that is assigned to an insulation code must contain insulation data.
Optionally, Spec-Driven Piping can create insulation quilts after you create pipe solids.
