I've seen a bad situation where BrickLink can told to use a particular shipping
method but the parts does not fit with the method, because on the restriction
on the dimensions. The problem is due to the absence of dimensions of one part
in the catalog.
In the Inventory page, I am able to list all items missing the weight in the
catalog. It would be great to have an identical filter to identify items without
dimensions.
[...] I suggest you try the checkbox: Instant Checkout Unavailable on your My Inventory page to find these items. Jen (39 months ago, Mar 19, 2021, to Suggestions)
