thanks it works however it is very limited in resolution.
most slicers make 1000 to 2000 slices but slicer for fusion limits to 100 maybe as high as 150.
i found a way around that limitation by saving bigger slices say 1 inch thick then then making 1 millimeter slices of each big slice.
that is like segmenting a 100 meg zip file into 10 segments of 10 meg then segmenting each segment into 10 segments of 1 meg.
the only downside i can see immediately is that some of the parts are small in the assembly viewer that it will not highlight the small p
