K-FACTORS

[BillRullan]

Anybody know how to obtain the K-FACTOR from a sheetmetal part in order to add it to a column in a family table? I have a generic part that can be made from a variety of materials, and I want to add a column to generate the appropriate developed lengths.

You can control the Y-factor and assign bend tables via material files. Then control the material (PTC_MATERIAL_NAME) in your family table. You will need to add each material to the generic part then specify it in the family table. This has worked well for me in the past and is our current practice. Rodney, WF3, M140

That's exactly what we tried in WF 4.0, but when we assigned material choice for each part in the family table, all parts in the family table re-generated to the most recent choice.

The way I control them (again, WF3 here, have not tried it on WF4) is thru relations. For example: IF MATERIAL==0 PTC_MATERIAL_NAME="SS" ENDIF IF MATERIAL==1 PTC_MATERIAL_NAME="AL6061" ENDIF IF MATERIAL==2 PTC_MATERIAL_NAME="STEEL" ENDIF IF MATERIAL==3 PTC_MATERIAL_NAME="BRASS" ENDIF Then I add the parameter "MATERIAL" in the family table. I would actually leave "PTC_MATERIAL_NAME" out of the table. If you have a flat instance you will need to ensure its values match the formed instance that you want. I will usually make a fomed and flat of each instance that I can verify. The drawback to that is it doubles your family table size. Hope this helps.
