To Create Pipeline Segments by Sketching
1. Click Follow > Follow Sketch. The Follow Sketch dialog box opens.
2. Select a sketch or click Define to create a new sketch. The Sketch dialog box opens.
3. Select references and click Sketch.
4. Sketch geometry, following a pipe centerline. Use the current sketching techniques. Remember to locate sketched geometry with respect to the assembly geometry to which the pipe placement references.
If the current corner type of the line stock is set to Bend, you can sketch arcs in addition to straight lines. However, you should use them to route pipelines around objects rather than to create bends in a pipeline. The system automatically creates bends in a pipeline at corners after you finish sketching.
5. Accept the sketch.
6. Position the sketch by setting the First End Offset and Second End Offset options.
◦ On End—Locates the point on the end of the sketch.
◦ Offset End—Locates the point the specified Offset distance from the end of the sketch.
◦ Offset Reference—Locates the point the specified Offset distance from the selected coordinate system or plane.
