Materials in Assemblies now shown as (Various) in BOM

[anders.blombergZUYWX]

I have an issue with drawings no longer show the material in the BOM in main assemblies. These are older files where this never has been a problem, the macro files have not been touched since they were created over a year ago.

this is the BOM for the main assembly, and item 5 to 9 suddenly does not have material appearing anymore, even no changes have been done in the sub-assemblies or parts.

in the sub-assembly drawing the BOM has not changed, and everything displays correctly.

All parts have the same material, but the assembly display (various) as material.

I have been using this file for over a year with no issues with the BOM, now suddenly most of my sub-assemblies have this issue. All parts have been set up with the same material.

what is going on?

Hi @anders.blombergZUYWX, thanks for posting.

When I checked some properties of your assembly I've noticed that some of the pieces have set a steel as physical material but PVC as appearance, please see the attached screenshot. Not sure if it will work, but make sure that all the components have assigned the same physical material.

Appearance only gives the look of the assembly or part of it. Physical material assigns properties in addition to appearance. The Properties option takes into account the assigned Physical materials. Probably assigning steel to some parts results in displaying Various values in Assembly Properties. This may happen for example when one of the parts was imported from somewhere.

Thank you for your reply, I have been messing around so much with the attached file so there may be errors.

I have found a solution, I had to remove all materials and re-apply them in the parts. There may have been two different versions of the PVC-U material that have appeared to be identical.

consider this issue to be solved
