Before inventor 2018 we had some BOM problems with visibilty or invisibility of the same ipt .
Now we have to check a box , all is ok for this.
If we check a list of part column using substitution we can see that the problem is already here ! sorry elsewhere ^^
So if you want a total mass column or total lenght column using substitution your total will be wrong if you have some invisible itp.
Have you got the same problem ? have you got a quick solution ?
Is it possible to update this ? it's very embarrassing. We have to cut the inventor automatism to give a good part list !!
Thanks
