Explode Assembly

Does anyone know of a program that does a good job exploding an assembly and inserting trail lines or whatever you want to call them?
I have an assembly with hundreds of parts and doing it all manually is painful and I am already losing money on the project without spending all that time on it.
I've tried a few things (have fusion 360 don't know it very well, did an export-import that didn't work very well) looked for other solutions but have not found one, cannot afford to buy
another full-blown cad seat
I love onshape and I know they are working on this, but this project has to move forward now.
Any good ideas?

That said, you have some options.
1) manually draw them in the drawing view.
2) model them as solids (not recommended)
3) create them as 2d sketches in part studios and insert into the drawing view - I would start here

Some time ago I created a few exploded assemblies using the "manually explode assemblies" described in your video ...
https://www.onshape.com/videos/exploded-views-in-onshape
At the time I created these as separate assemblies.
Does the latest release of Onshape with Assembly Configurations now allow me to create a "Constructed Assembly" configuration and "Exploded Assembly" configuration within a common Onshape assembly?
Thanks
You can now configure mate offsets - this could be used to make exploded views.
Your might find reading this forum post exchange from ~ 2 yrs ago enlightening.

I revisited the creating exploded assembly subject now that "Assembly Configurations" are now possible.
This is what I have determined so far...
Things have improved. Assembly configurations can be used create and manage exploded configurations. However, the process is incredibly tedious and falls way short of what is need.
Here is what I currently do to create and manage exploded assemblies.
1. Create an assembly configuration where every assembly constraints is suppressed. I call mine "All Constraints Suppressed". This is necessary to give the person creating the exploded assy absolute control over freely positioning instances relative to one another.
This becomes complicated if the assembly contains instances of assemblies and has multiple configurations for the purpose of defining different products.
2. Create an new assembly tab and instance in the assembly to be exploded using the "All Constraints Suppressed" configuration. Using a different assy tab is highly recommended to separate product definition and design function configurations from "configurations" (alternate representations) that are documentation related. Some even recommend using different documents. Trying to keep everything in a single document, while technically feasible is not practical, from an human usage standpoint. Named Positions, Display States, and Named Views which are specific to the documentation process are separated out make it a lot easier to manage and use.
The ability of "Assembly Configuration" is huge improvement because it is now possible to create exploded assemblies were the user has maximum freedom to reposition instances and STILL have the assembly hierarchy linked to the real "design" assembly. Prior to Assembly Configurations one had to create an unliked copy with no constraints.
Hint: This would be so much more simpler if users had the ability to "override" configurations/constraints in a instanced (linked) assembly.
If anyone out there knows of a better way please share it.
