This Knowledge Base article was created to provide an alternate method in removing the top rail on a Farmhouse sink:
Changes made on the part tab are "overrides", and those changes can lose their "cabinet intelligence".
Here is an alternative way to build it:
Try to save 'Part Tab' modifications for when the other tabs and big blue boxes won't work. (see red squares below)
From the face tab, you will want to first delete the interior sections to the left of the sink
Then delete the top rail
Next, turn the top section on the left side to Open and TYPE IN the Height Field: 0
(typing instead of sliding makes sure you get the center style set to the very top)
Resection the left section.
This will make you Face Tab look correct (it is the same view used on the assembly sheet)
And you will not need overrides on the part tab.
