Hi Jon
It doesn't seem as though it's been designed to work for creating multiple exploded stages of one model. The timeline makes the process much slower when turning off newly added components to an assembly.
We create step-by-step style multi-sheet assembly drawings that start from basic components and work through to finished assemblies. In 2016 we would create the basic stages using representations in the IAM, then use those to create exploded views in the IPN. From then on it was very simple to drop each view on to the drawing.
If a new component was added? Simply turn it off in the IAM representations. Hotkey Visibility (can’t do that in IPN but we rarely needed to), and if it was a single screw buried within hundreds we could use the ‘show mates’ function to locate it. Simple.
If it was an older IPN that had un-associated exploded views in it – fine, we could still turn the parts on and off quite easily.
We don’t create animations or explode entire assemblies because we find that detailed drawings are a much, much clearer method of conveying detailed information. So forcing us to use a function that is primarily designed for animations and ‘sort of works for drawings’ isn’t really good enough.
To get this to work in 2017, I am:
- Opening the legacy IPN, finding that the exploded views have been converted to 'scenes' and each given a snapshot. The snapshot is associative if there were tweaks in the explosion, and independent if there were no tweaks.
2. In the scene, making invisible the newly added component to the assembly. This action appears in the timeline. Note at this stage in 2016, I would be finished with this process and the drawing would have updated itself with no further actions.
3. Expanding the timeline and finding the invisibility action on that part, and moving the slider backwards so the action happens before the snapshot position. This takes longer when several components are being turned off. So I’m essentially having to tell the software twice that I want to make something invisible. Great.
4. Hitting refresh on the snapshot.
5. Opening the snapshot, only to find that the components I wanted to disappear have not done so, but are still in view. This seems like a bug.
6. Closing the snapshot and wiggling the invisibility slider on that component again. The snapshot then wants to refresh again.
7. Refreshing and checking the snapshot, to find that the action has now been successful.
8. Creating a new drawing view? Can’t rely on the IPN view any more. The snapshot has to be updated, followed by clicking ‘update camera’, followed by having to select the snapshot view in the little dropdown menu in the drawing view options. This is much less intuitive than just setting the view angle in the IPN and letting that carry through straight onto the drawing.
Need to change the angle on an existing view? Clicking on the view-cube and using ‘custom orientation’ doesn’t take you back to the view in question any more – nope, it now takes you back to whatever scene happens to be open in the IPN which may or may not be the view you’re trying to alter. Impossible to accurately change the angle of a small sub-assembly.
Six extra steps, with the inclusion of a variety of independent and associative snapshots (do I change the scene, or the snapshot? Or both?), extra actions to perform to achieve something that only took 2 actions before.
Further, the snapshot thumbnails aren’t large enough to accurately show what that snapshot contains. The snapshot description text is cut short so you can’t see the entire description, meaning each snapshot needs opening to check that what you are about to drop onto the drawing is actually what you want. At least in 2016 you could see the name of each exploded view in the browser.
Multiply this by the hundreds of updates we perform to drawings day to day, and you’ve got hours and hours of our wasted time.
On top of this, there seems to be a problem with components appearing at random in the 'scenes' when a legacy IPN is opened, which is destroying the views on the drawing. I can’t work out if it’s related to the scene being associated to the IAM representation or not.
I currently have a legacy IPN with about 30 views in it – none are associated to the IAM, but some have retained their correct views and others have reverted to showing the entire model, every part visible which I then have to manually turn off again. Turning on and off the associativity to the model makes no difference, so I'm stuck with it. This apparently happens at random and not necessarily straight away when the IPN is opened.
I’ve sent datasets and various descriptions of the problem over recently to other Autodesk members and spent hours and hours of our time repairing broken IPN views. It’s crazy – I’m having to reference back to old revision drawings to repair the scene views that this software has broken!
So two different things here (sorry for the lengthy text). Some usability issues and some apparent bugs. I’m hesitant to believe that a few tips or tricks will make these changes any easier to swallow, really.
Cheers
