We need a better technique for assembly cuts used in large fabricated weldments. In general I am against assembly features because of the large regeneration times.
In the past I learned to use the merge technique to create two different objects; the first is weldment assembly with no drilled holes and no tap threads (due to common beams used across the weldment structure).
The second object is a part (not assembly) that has all the structural beams merged into a single blob. Here we can apply features to a part, but the problem is that we lose the boundaries between all the touching models that were merged into one. It really looks wrong in drawing mode, when you cannot see these boundaries.
The problem with parts merged, is that you lose all the internal boundaries. The part now looks like a casted part containing the outer shape but with no boundaries for the drawing. There are no internal boundaries once merged - the object is now a single closed solid. The work around now is to manually draw curves in the new merged part to represent the lost boundaries.
I am requesting an enhancement to see the original boundaries that existed before the merge. There should be an option during the merge process to select “create component boundaries”.
