I am making the production drawings for the assembly and each part is a seperate page. One part's flat pattern will not flatten per say on the drawing for some reason. The model part when you suprress the flat patter unfold just fine, but will not do so in the drawing? Am I over looking somethin?
If you are saying you have different sheets for each part and they are part of an assembly drawing, I suspect that you are not selecting the individual part model that you want to "flatten" but rather the drawing thinks you are trying to flatten the assembly. If you have selected the proper view containing the model you want to show flattened, there is likely a "flat" version view available in the view pallet.
If you get a chance to search the discussion forum, there have been several threads concerning questions about multipart drawings. I would suggest individual drawings for each part to avoid some surprises. This also allows a part and it's drawing to be used more easily in other projects.
