when I do drawing for an assembly, sometimes the box around it is too big, and why it doesn't size automatic to the assembly borders ?
It generally does size to fit the assembly fairly closely, although I agree that it would be nice to be able to size them manually. Do you perhaps have a sketch that extends past the assembly components, even if it's hidden? Or maybe a sketch with an infinite length construction line? I don't use them myself, but I understand they can sometimes cause issues. Another possibility is a small part that's off in space. With your assembly open, if you go to Shift+C to center the model on your monitor, does it fill the screen, or is it off to one side?
there is nothing and it is really bothering me in the drawing since that empty space is overlapping on other views in the drawing.
A pretty easy solution is to draw a box the size you want the boundary and then form a crop view.
it seems good idea Jamil but I am wondering why this problem is happening and if it can solved without tricks.
I have found that if I have saved a sub-assembly in its exploded view state, the bounding box in the assembly it is used in will be as large as the bounding box needed to surround the sub-assembly's exploded state - even if the sub-assembly is not exploded in the current assembly.
So, I try to remember to save my assemblies in their collapsed state.
Hope this helps.
thanks Melissa but I don't have an exploded view, this problem happens not for all files though.
