Daniel,
Let’s step through this.
The Width setting in the Pipe Data dialog is there to give the mainline a visible width in Modelspace, without having to turn Lineweights on, or run a print preview.
Meanwhile, the schedule displays a block (LAFX-PIPE-MAIN), thus giving you full control of what is displayed. The only consideration in editing this block, is that it would be nice to be able to place the schedule into Paperspace or Modelspace.
So one option would be to simply edit the schedule block and make the displayed polyline 0.06” wide. This would merit a quick check that if placed into Modelspace, the width was correctly multiplied by the block scale.
So one may instead opt to just set the layer used in the schedule block to a color that will print at 0.06” — this has the added benefit of being able to be altered through the CTB.
The goal of course is to avoid any manual steps. There is no reason to consider manually placing pipe in the schedule. Since there is a single block used for the mainline in the schedule, the only consideration is in how to edit it.
