In the past, I recall that there were max numbers for input sizes and numbers of inputs, however I can no longer find that info in the documentation. Do these limits still exist? The only mention I can find of them is in the Inventor release notes in the DA documentation: https://forge.autodesk.com/en/docs/design-automation/v3/change_history/inventor_release_notes/
The quotas page linked can't be found. https://forge.autodesk.com/en/docs/design-automation/v3/developers_guide/quotas/
There are no limits for max numbers for input sizes and number of inputs, etc. anymore. The quotas information can be found here.
