seems there are not many questions or things to discuss? Well one thing about the Vasari Plugin: Vasari still seems to be quite unstable and the API doesn't support many things. I'm stillw aiting for updates from Autodesk - so far nothing happens.

Dear CPA,

thank you for your feedback, the issue is caused by the SortCurves method in Revit so it might be an issue of unsupported geometries in the outline of a slab or sth similiar you are trying to send. please send me your gh file to support AT grevit DOT net.

Thank you

I am having similar issues. Is it a port or IP issue that could be causing this. See included screenshots for error message.

A transaction or sub-transaction was opened but not closed. All changes to the active document made by External Command will be discarded.

I give assistance.

Dear Grevit users,

the latest version automatically creates IDs for Grevit objects, the update mode is turned on by default and the Grevit client in Revit/ACA closes automatically after receiving data.

Dear Grevit Users,

thank you for all the great input i received via mail. i've been on vacation the last weeks, that's why there hasn't been any new release. The next release will support surfaces as an input for most of the elements and also a Family/Type loader to make it easier to select correct family names. And then moving the project Open Source because there are many great feature requests I cannot handle with my limited amout of time.

regards, Max

Really useful!

got a feedback that the current implementation supports a maximum of 22800 components per transaction (thanks to Luke).
