"...wondering if i could imort the pz3 into the approximate samre spot..." When you say, "the pz3" I assume you mean the prop. I end up doing this little routine under similar circumstances quite a lot: 1 -- With the pz3 containing your 'old' prop open in Carrara, import your 'new' prop by whatever method you prefer. 2 -- With the 'old' prop selected go to the Motion tab of the Assemble Room and click on the "HP>obj" button. 3 -- Select the 'new' prop and do the same as step two. 4 -- Make note of the x, y and z coordinates of the 'old' prop (the topmost set of numbers in the "Transform" window of the Motion tab). 5 -- Select the 'new' prop and enter the values you noted in step 4. 6 -- Delete the 'old' prop. There are times when you won't want to mess with the hot point (the HP>obj button) but most of the time it probably won't matter. Make backups before you do anything, as always ;)
