Okay,

I created an assembly and then created an a drawing with 3 sheets on it. The first sheet shows the assembly with a BOM and the following sheets show the detailed drawing for the parts withini the assembly. Looks good. Now the problem is that I had to modify the assembly by adding three more detailed parts and modify one of the original.  So I created the new parts and saved them. Then I modified the one and saved it with the same part number with a "b" on the end of it (Rev. B). Then I open the original assembly and "find and replace" the old part with the modified part and saved it as a Rev. B just like the part. I then opened the Assembly Drawing and the assembly on Sheet 1 is changed to show new parts and all. But sheet 2 is still referencing the original Unmodified part. All I need to do is have the drawing update on sheet 2 and add another sheet for the newly created parts. How do I do this without having to create and re-dimension the part on sheet 2 which only has 4 holes added to it. I tried looking for a way to change the part it is referencing to but just haven't figured it out. Is there an easy way to do what I want?
