A few months ago there was an occasion where a colleague needed to swap out some clamps that were product listed for a different size. The simplest method would have been to just do a swap in, but the problem with that method was that the clamps had unique spool names and custom data that would be overwritten if a swap in was performed. This made me decide to look into changing a Job Item product list line entry through the Fabrication .NET API. For more information about getting started with Fabrications Items through the .NET API see the post [Accessing Fabrication Items Through .NET]/posts/accessing-fabricaton-items-through-net/.
The code below has the user select some fabrication objects, then displays a dialog with a drop down of all unique Product List names within the user selection. The user then selects a name from the drop down and hits “OK”. The selected items that have that product list name entry are then updated. It should be noted that the items will not be dynamically stretched/relocated like they would if you used “revdesign” to updated items with Design Line, so you would need to go back through and make any adjustments where needed. The benefit would be the fact that unlike Design Line, all of the user imputed data like “Spool Name” will not be overwritten.
