I have a complex assembly that took a while for me to put together. Now that I need to do some final adjustments it is acting wonky.
I need to make the left door opening of the left cabinet of the assembly 1/16" larger but when I bring it into the FF editor it gives me some crazy opening measurements.
I found a couple of issues with various parts not wanting to play well with each other.
On the right cabinet, the left side couldn't be edited, kept getting errors.
On the left cabinet, I deleted the top and reinserted it and that seemed to get rid of that cabinets problem.
Now I have an issue that I can't get it to put a dado on the backside of the right and left sides of the left and right cabinets. That one is still unsolved.
Interesting situation. It took me a few minutes, but I have finally reproduced what you are seeing. If you take an assembly of cabinets (that have face frames) from the custom layout area to the cabinet editor, you will get these goofy looking FF section sizes. It appears to only do this when taken from the CL, loading the assembly directly into the cab/assm editor or from the batch will not present this anomaly. I will get this listed and fixed. For now, If you need to modify an assembly cabinet from the custom layout, you can regen the cabinet (select Construction Settings and then select OK) first and then go into the face frame editor and the section dimensions will show correctly.
